View and export
SVG files on Windows
SVG Explorer adds native SVG support to Windows Explorer — thumbnails, previews, and file properties — plus a dedicated app for viewing and batch-exporting your SVG files to any image format. It can also register SVG across Windows (administrator required), so thumbnails, previews, and file properties show even when another app is your default.
Installation
SVG Explorer is distributed through the Microsoft Store as a single package that installs both the desktop app and the Windows Explorer shell extensions.
No configuration needed. After installation, SVG thumbnails and the preview pane will work automatically in Windows Explorer. Just navigate to a folder containing SVG files.
What gets installed
SVG Explorer App
A desktop app for opening, viewing, and exporting SVG files. Accessible from the Start menu.
Shell Extensions
Background components that power SVG thumbnails, the preview pane, and file properties in Windows Explorer. These run automatically — no action needed.
The Interface
SVG Explorer has a simple left-hand navigation with four pages. You can open SVG files by clicking Open SVG File, dragging a file onto the window, or launching it from Windows Explorer.
Opening a file is required before the Images and Export pages become usable. The Home page always offers an Open SVG File button to get started.
Opening a file
There are three ways to open an SVG file in the app:
- Click Open SVG File on the Home or Images page and pick a file from the browser dialog.
- Drag and drop an SVG file from Windows Explorer directly onto the SVG Explorer window.
- In Windows Explorer, right-click an SVG file and choose Open with → SVG Explorer. The app opens and goes straight to the Images page.
Windows Explorer Integration
Once SVG Explorer is installed, Windows Explorer gains three new capabilities for SVG files — no extra steps required.
SVG Thumbnails
SVG files display their actual graphic content as a thumbnail in Explorer's icon view. You can see what's inside each file without opening anything.
Preview Pane
Select an SVG file and press Alt+P (or use View → Preview Pane) to see a live, zoomable preview directly inside Explorer — no app launch needed.
File Properties
The SVG's dimensions, and any title, description, author, copyright, and keywords embedded in the file, appear in Explorer's Details pane, the info tooltip, and the file's Properties → Details tab. Add them as columns in Details view too.
An optional Better Shell Integration (administrator required) registers SVG thumbnails, previews, and file properties, and makes them appear even when another app is your default for .svg. Turn it on from Settings → Shell Integration — see Better Shell Integration.
Using the Preview Pane
The preview pane renders your SVG at full quality. Here's what you can do inside it:
| Action | How |
|---|---|
| Zoom in / out | Hold Ctrl and scroll the mouse wheel |
| Scroll the image | Use the scroll bar or scroll the mouse wheel |
| Pan | When zoomed in, drag the image with the mouse |
| Change background | Right-click the preview for a list of background colours (white, grey, black, checkerboard, and more) |
| Reset view | Right-click and choose a background colour to reset the zoom or choose (Unset) to reset to default background. |
The preview is drawn in the background, so Explorer never freezes on a large file. While a big SVG is being drawn, or redrawn after a zoom, the previous image stays on screen, scaled to the new zoom. A small spinner appears in the middle of the pane once you stop zooming or panning and the drawing is still running.
Checkerboard background: right-click the preview and choose Checkerboard to display transparent areas as a grey-and-white grid — useful for checking how your SVG looks with transparency. It's also a common standard for representing transparency in image editing software, so it can help you spot any unintended transparent areas in your design. Also its size is fixed at 10x10 pixels, so it gives you a sense of scale when zooming in and out.
Thumbnail background
By default, SVG thumbnails have a transparent background, so the Windows Explorer background shows through. You can change this in Settings → Explorer Integration → Thumbnails background, which offers three modes:
- Transparent — the default. The Explorer background shows through.
- Fixed colour — fill every thumbnail with a colour you pick.
- Adaptive — per image, add a light plate behind dark artwork or a dark plate behind light artwork, so the thumbnail stays readable on any Explorer background. Colourful artwork is left transparent.
Adaptive is handy if you keep dark, monochrome icons that would otherwise vanish against a dark Explorer background. Its thresholds and plate brightnesses are adjustable with sliders (under Adjust…), and because the backing is chosen from the image itself rather than from your Windows theme, thumbnails stay correct in both light and dark mode without regenerating on a theme switch.
Windows caches thumbnails, so changing the thumbnail background won't repaint existing thumbnails right away. Use Settings → Explorer Integration → Reset Thumbnails to have Windows rebuild its thumbnail cache and pick up the change.
When the trial has ended. Once the free trial is over and the app is not licensed, Windows no longer starts SVG Explorer at all. File Explorer then shows the file type's plain icon instead of a thumbnail, the preview pane stays empty, and the file properties SVG Explorer adds are not shown. With Better Shell Integration installed you see a small Trial expired placeholder and a trial notice in the preview pane instead. Opening a file with the app shows an error, see File system error (-2143322102). Get the app from the Microsoft Store to restore everything. Your files are never changed.
Why a few thumbnails still show. With the trial over you still see real thumbnails here and there, mixed in with the plain icons. Two things produce them. Windows keeps a thumbnail cache of its own, so pictures made while SVG Explorer was licensed stay in the folders you have already visited, until that cache is rebuilt. And with Better Shell Integration installed, the first files a fresh Explorer session asks about can still be drawn, because SVG Explorer answers Explorer straight away rather than hold it up while the Store confirms the licence, and those few are cached as well. A mix of icons and thumbnails is expected, it does not mean the trial is still running. The leftovers go away on their own as Windows rebuilds its cache.
Better Shell Integration (administrator required)
SVG Explorer can register its SVG handlers with Windows itself. This turns on SVG thumbnails, the preview pane, and the Explorer file properties for all .svg files. Because it changes the machine, Windows asks for administrator approval when you turn it on or off.
This is optional. The SVG Explorer app itself works without it. Turn it on when you want SVG thumbnails, previews, and properties in File Explorer even when another app is the default for these files.
It works even when another app is your default. If you open SVG files in another program (say a graphics editor) and keep it as your default, SVG Explorer still supplies the thumbnails, previews, and properties. Windows uses them as a fall-through when your chosen app doesn't provide its own, and your default app for double-click stays exactly as you set it.
For your account, not everyone on the PC. Installing it needs an administrator, but it only works for a Windows account that has SVG Explorer installed and licensed. If the app is uninstalled, the thumbnails, previews, and file properties stop working too, even while the integration is still listed.
Install, update, uninstall
Everything is done from Settings → Shell Integration. The card shows the current status and the matching action button, and each action prompts for administrator approval (a standard Windows UAC dialog).
| Status | Meaning | Button |
|---|---|---|
| Not installed | SVG Explorer's handlers are not registered with Windows on this PC. | Install |
| Installed | Registered on this PC and current. | Reinstall / Uninstall |
| Installed, update available | A newer build ships with this app version than the one registered. | Update / Uninstall |
Listed in Windows. It also appears in Settings → Apps → Installed apps as "SVG Explorer Preview Shell Integration", and can be removed there at any time, independently of the SVG Explorer app.
Give it a minute. After you install it, thumbnails can take a while to appear. Windows caches how it resolves thumbnail handlers, separately from the picture cache, so a folder may show the old icons for a bit. Wait a little, or run Reset Thumbnails (see Settings) and press F5.
Why it needs administrator, and why updates are separate
Windows resolves thumbnail, preview, and property handlers from a location that only an administrator can write. That is why this integration asks for approval. It's copied to a stable folder outside the app package, so it keeps working across app updates. Because it lives outside the app package it doesn't update itself, so a newer app version flags update available and one click refreshes it.
Viewing SVGs
The Images page is SVG Explorer's main viewer. It renders your file at high quality and lets you zoom and inspect it in detail.
Large files are parsed and drawn in the background, so the app stays responsive. When loading or redrawing takes more than a moment, a Loading… spinner appears over the image.
Fit
The three fit buttons in the toolbar size the image to the viewer, always keeping its proportions:
| Button | What it does |
|---|---|
| Fit to window | Shows the whole image, as large as the viewer allows. |
| Fit width | Makes the image as wide as the viewer. Scroll or drag to see the rest vertically. |
| Fit height | Makes the image as tall as the viewer. Scroll or drag to see the rest horizontally. |
The fit you pick is remembered, and applied to every file you open. It also follows the window when you resize it. As soon as you zoom by hand, the fit is released for the current file, click a fit button again to get it back.
Zoom
Use the Zoom dropdown in the toolbar to jump to a specific zoom level: 10%, 25%, 50%, 75%, 100%, 125%, 150%, 200%, 400%, and more. You can also type a custom percentage into the box. 100% is the size defined in the SVG itself.
While looking at the image, hold Ctrl and scroll the mouse wheel to zoom smoothly. The zoom is centered on the mouse pointer, so the point under it stays in place, and the Zoom box follows the current level.
Pan
When the image is larger than the viewer, scroll bars appear. You can also move around with the mouse:
Performance on large drawings
SVG Explorer only draws the part of the image you can see, at the current zoom, so zooming deep into a big drawing costs about as much as viewing it whole. What takes time is the drawing's own complexity: the number of shapes, filters, and embedded images it contains.
| Situation | What happens |
|---|---|
| Zooming or panning | The previous picture stays on screen, scaled and moved to the new view, while the sharp one is drawn. The viewer never goes blank. |
| Zooming quickly | Only one drawing runs at a time, and the most recent view always wins, so a burst of wheel zooms does not pile up work: the app goes straight to where you stop. |
| A drawing that takes a while | A spinner appears once drawing takes more than a moment, and the app stays responsive the whole time. |
The File Explorer preview pane works the same way. It draws in the background, so Explorer never freezes, even on a very complex SVG. While you keep zooming with the wheel, it waits for you to stop before drawing, so a quick burst of zooms is drawn once, where you land.
Background colour
Click the Background Colour button (top-right of the Images page) to open a colour picker and set the background shown behind the SVG.
| Option | What it does |
|---|---|
| Checkerboard toggle | Shows transparent areas as a grey-and-white grid. When enabled, the colour picker is disabled. |
| Colour picker | Choose any colour including alpha (opacity). Your choice is remembered when you reopen the app. |
| Transparent button | Resets the background to fully transparent (no colour fill). |
This is the same setting as Settings → Explorer Integration → SVG background colour — change it in either place and both stay in sync. Your choice is remembered, and it is also the fill for exports made with Preserve Transparency off.
Image information
Below the page title, SVG Explorer shows the intrinsic dimensions of the file — the width and height as defined in the SVG itself (typically in pixels). This is the "native" size of the artwork, independent of how you've zoomed the viewer.
SVG is a vector format, so you can zoom to any size without quality loss. The intrinsic dimensions are only relevant when you export the image.
Exporting Images
The Export page converts your SVG into raster images (PNG, JPEG, etc.) or PDF. You can export at multiple sizes in a single click — great for producing icon sets or assets at standard dimensions.
The navigation menu has two entries for it:
| Entry | What it does |
|---|---|
| Export as images | Exports image files, in the format chosen in the Image format list. |
| Export as PDF | Exports one PDF document per size. There is no format to choose. Each document carries its metadata, filled automatically: the title is the SVG file name, the author is your Windows user name, and the creator and producer name SVG Explorer and its version. |
Export settings
| Setting | Description |
|---|---|
| Output Folder | Where exported files are saved. Defaults to Pictures\SVG Explorer. Click Browse to pick a different folder, or Open Folder to view the current destination in Explorer. |
| File Name Template | Controls how exported files are named. Uses tokens like {name} and {size} — see the token reference below. A live preview shows what the file name will look like. |
| Image Format | The output format when exporting as images: PNG, JPEG, BMP, HEIC, and others. See the full list below. Hidden when exporting as PDF. |
| Overwrite | When on, existing files with the same name are overwritten silently. When off, existing files are skipped with a warning. |
| Preserve Transparency | When on, the exported image keeps transparent areas. When off, the export is fully opaque: transparent areas are filled with the background colour of the Images page, laid over white, so a transparent background gives white and a semi-transparent one a lighter shade. Only available for formats that support transparency (PNG, PDF, BMP with alpha, etc.), the others, like JPEG, always get this fill. |
Export sizes
Each row in the size list represents one output file. The number is the pixel size — the SVG is scaled to fit within a square of that size. Default sizes are 16, 32, 48, 64, and 256 pixels.
Add Size
Adds the next standard size (16→32→48→64→256). If all standard sizes are already added, it doubles the largest existing size.
Clear All / Remove
Click Clear All to remove every size, or click Remove next to a single row to delete just that size.
You can also edit the size number in any row directly — click on it and type a new value, or use the up/down arrows. Sizes are always sorted smallest to largest.
Running an export
- Open an SVG file on the Images page first.
- Choose Export as images or Export as PDF in the navigation menu.
- Set your Output Folder, Format (images only), and Sizes.
- Click the blue Export button. A toast notification confirms how many files were saved.
The Export button is disabled if the output folder path is invalid, the file name template is missing {size}, no sizes are listed, or no format is selected. A red message explains what needs to be fixed.
File name template tokens
Customise how exported files are named using these tokens in the File Name Template field:
Example template: {name}_{size} produces files like icon_16.png, icon_32.png, icon_256.png. The {size} token is required — the Export button won't activate without it.
Recent Files
The Recent page keeps a list of SVG files you've opened before, so you can jump back to them quickly.
| Action | Description |
|---|---|
| Click a file link | Opens that SVG file in the viewer, navigating to the Images page. |
| Clear Recent | Removes all entries from the history list. You'll be asked to confirm if the list isn't empty. |
| Remove Missing | Scans the list and removes entries for files that have been deleted or moved. |
The recent files list stores up to 100 entries by default. You can disable it entirely in Settings if you prefer not to track recently opened files.
Settings
The Settings page groups its options into Appearance & behavior and Explorer Integration. Some configuration still happens in context too — for example, zoom on the Images page and export options on the Export page.
Appearance & behavior
| Setting | Options | Description |
|---|---|---|
| Theme | Light Dark System | Controls the app's colour scheme. System follows your Windows light/dark mode preference. |
| Recent Files | On / Off | When turned off, SVG Explorer stops recording recently opened files. If you turn it off while the list has entries, you'll be asked whether to clear them or keep them. |
Explorer Integration
These options control the background used behind the in-app preview and the way SVG files are rendered inside Windows Explorer.
| Setting | Description |
|---|---|
| SVG background colour | Sets the background shown behind the SVG in the in-app viewer, and the fill used for exports. The flyout has a Draw checkerboard toggle, a full colour picker (with alpha), and a Transparent shortcut. This is the same setting as the Background Colour control on the Images page — changing it in one place updates the other. |
| Thumbnails background | The background used when generating SVG thumbnails in Windows Explorer, chosen from a drop-down: Transparent (the default), Fixed colour (pick a colour), or Adaptive (a light or dark plate added per image so artwork stays readable on any Explorer background; thresholds and plate brightnesses are adjustable with sliders). Because Windows caches thumbnails, run Reset Thumbnails after changing it to see the effect. |
| Reset Thumbnails | Asks Windows to rebuild its thumbnail cache so changes to thumbnail-related settings take effect across Explorer. You'll be asked to confirm before it runs. You can also clear the cache with Windows' built-in Disk Cleanup tool: press Win+R, run cleanmgr, tick Thumbnails, and click OK. |
| Shell Integration | Installs, updates, or removes the registration that makes SVG Explorer's thumbnails, preview, and file properties show even when another app is your default for .svg. Each action needs administrator approval. See Better Shell Integration for the full walkthrough. |
Each colour setting shows a small preview swatch next to Choose colour that reflects the current colour. Transparent or semi-transparent colours show a checkerboard through the swatch, and the SVG background swatch shows a full checkerboard while its checkerboard option is turned on.
Some settings are saved automatically as you use the app and don't have their own control on the Settings page — your last-used export folder, file name template, image format, and export sizes. Together with the options above, they're all stored in a settings.json file in your local app data folder.
Supported Export Formats
SVG Explorer can export to all image formats registered on your Windows system, as well as PDF. The list below shows the most common ones. Formats marked with a green dot support transparency (alpha channel).
* HEIC/HEIF requires the HEIF Image Extensions package from the Microsoft Store or any third-party codec that registers HEIC/HEIF support on the system. If it's not installed, this format won't appear in the list.
* PDF saves one PDF file per export size. Each PDF contains a single page with the SVG rendered at the specified dimensions. Transparency is supported if your PDF viewer supports it (Adobe Acrobat, Edge, InkScape and others do; some viewers may not).
Best for icons: use PNG with Preserve Transparency on. PNG is widely supported and produces pixel-perfect icons at any size with full alpha channel support.

Tips & Tricks
Producing a complete icon set
- Open your SVG in SVG Explorer.
- Go to the Export page. The default sizes (16, 32, 48, 64, 256 px) cover the standard Windows icon set.
- Choose PNG format with Preserve Transparency on.
- Use the template
{name}_{size}so files are namedmyicon_16.png,myicon_256.png, etc. - Click Export. All five sizes land in your output folder in one go.
Checking transparency before exporting
On the Images page, turn on the Checkerboard toggle (inside the Background Colour flyout). Transparent areas of your SVG will show as a grey-and-white grid — a quick way to confirm the artwork has the alpha you expect before exporting.
Keeping the recent files list tidy
If you move or delete SVG files, their entries remain in the recent list. Go to Recent Files and click Remove Missing to clean up any broken links automatically.
"File system error (-2143322102)" when opening a file
If double-clicking a file, or choosing Open with → SVG Explorer, shows a message with the file's path and File system error (-2143322102), your free trial has ended. Windows refuses to start an app whose Store licence is no longer valid, and that number is the Store's licensing error, 0x803F800A, which Windows shows without an explanation. Nothing is wrong with the file.
Get SVG Explorer from the Microsoft Store and the files open again. Until then you can open them with another app, or make another app the default for them in Windows Settings → Apps → Default apps.
Thumbnails or previews don't show (another app is the default)
Windows 10 is the strict case. On Windows 10, whichever app is the default for a type owns its thumbnails and preview outright, so those appear only once you make SVG Explorer the default for the type, or install Better Shell Integration.
Windows lets only one app provide thumbnails and the preview pane for a given file type: the app currently set as the default for that type. If another installed program also handles SVG files and is set as the default, Windows uses its thumbnails and preview instead, so SVG Explorer's may not appear. You have two ways around this: turn on Better Shell Integration, which registers SVG Explorer's handlers with Windows so they show up regardless of the default (a one-time, administrator-approved setup), or set SVG Explorer as the default for the extension with the steps below.
- Open Windows Settings → Apps → Default apps.
- Find and click SVG Explorer in the list (type its name in the search box if needed).
- For the
.svgfile type, click the current handler and choose SVG Explorer as the default.
Thumbnails and previews always follow the file type's default app. After changing the default, run Settings → Reset Thumbnails if Explorer still shows old cached thumbnails.
Preview stays blank for files downloaded from the internet
Starting with Windows 11 25H2, Microsoft blocks the File Explorer preview pane for files that carry the "Mark of the Web" — files downloaded from the internet, or coming from a location Windows considers unsecured. This affects every file type, not just SVG, and it is a Windows security decision: there is nothing SVG Explorer can do at its level to override it.
How to restore the preview: right-click the file → Properties, tick Unblock at the bottom of the General tab, then click OK. To clear many files at once, PowerShell's Unblock-File cmdlet does the same in bulk.
Microsoft has acknowledged this behaviour. For the full explanation and more ways to re-enable previews, see this Windows Latest article — in particular its "How to unblock previews in File Explorer" chapter.
Dark mode
SVG Explorer follows Windows theme settings by default. If you prefer a fixed theme regardless of system settings, go to Settings and choose Light or Dark explicitly.
Single instance: SVG Explorer runs as a single window. If you open it from Explorer while it's already open, the existing window is brought to the front and the new file is loaded — you don't get two windows.
If SVG Explorer has earned a spot in your workflow, a quick rating on the Microsoft Store helps other people discover it, and it means a lot to our small team. It takes less than a minute.
