SVG thumbnails and previews in Windows File Explorer

When File Explorer shows SVG files as plain icons, a folder of cut files or logos has to be opened one file at a time to find the right one. Microsoft’s answer is PowerToys, its free set of utilities for Windows 10 and 11. Its File Explorer add-ons draw SVG files as thumbnails and show them in the preview pane. Turn on two switches and the folder shows the pictures.

This page follows Microsoft’s PowerToys documentation as it stood in October 2026, when release 0.101 from August 2026 was the current one.

What you need

Microsoft lists these minimum requirements for PowerToys:

• Windows 11, or Windows 10 version 2004 (build 19041) or newer.
• A 64-bit processor, x64 or ARM64.

On an older build of Windows 10, update Windows first. The extension described further down is the other choice, though its page does not say which versions of Windows it supports.

Install PowerToys

Microsoft recommends installing from GitHub or the Microsoft Store.

• Microsoft Store: search for PowerToys and install it.
• GitHub: on the Microsoft PowerToys releases page, open Assets and download the PowerToysSetup file for x64 or arm64, then run it.
• WinGet: in a terminal, run:

winget install --id Microsoft.PowerToys --source winget

There are two kinds of installer, one for the current user only and one for every user of the computer. Either works for this.

Turn on SVG thumbnails

1. Open PowerToys Settings and go to File Explorer add-ons.
2. Under the thumbnail previews, find SVG and set it to On.
3. Open a folder of SVG files in File Explorer.

Microsoft’s note on this: “A reboot may be required after enabling the thumbnail previewer for the settings to take effect.” If nothing changes, restart the computer before trying anything else.

The same list covers PDF, STL, G-code and QOI files, each with its own switch.

Turn on the preview pane

The preview pane is the part of a File Explorer window that shows the contents of the selected file. It is a different feature from thumbnails, with its own switch.

1. In PowerToys Settings, under File Explorer add-ons, set the SVG entry in the Preview Pane section to On.
2. In File Explorer, show the pane. Microsoft’s instructions are the same for both versions of Windows: go to View and select Preview pane.
3. Click an SVG file. It is drawn in the pane.

If the pane stays empty, Microsoft points to a Windows setting that can block it: in File Explorer choose Options, open the View tab, and make sure Show preview handlers in preview pane is ticked in the list of advanced settings.

Expand the Scalable Vector Graphics section in PowerToys to find one setting for the previewer, Checkered shade, which sets the background shade behind the drawing. In Microsoft’s words, “this helps visualize transparent areas in SVG images.”

Things that go wrong

What you see	Cause, from the documentation	What to do
No thumbnails after switching on	A restart may be needed	Restart Windows
Thumbnails in some folders but not in OneDrive	“Thumbnails might not appear on paths managed by cloud storage solutions like OneDrive, since these solutions may get their thumbnails from the cloud instead of generating them locally”	Copy the files to an ordinary local folder
A white logo shows as a blank preview	“It isn’t possible to change the background color of the preview pane, so if you’re working with transparent images with white shapes, you may not be able to see them”	Try the Checkered shade setting, or open the file in a viewer with a dark background
Another program’s preview stopped working	“Enabling the preview handlers will override other preview handlers already installed”	Switch off the PowerToys previewer for that file type
The preview pane is empty for every file	Preview handlers are turned off in Windows	Tick Show preview handlers in preview pane

For white or pale artwork, the SVG viewer has a dark background switch and a checked background that makes transparent parts obvious.

The other add-on: SVG Explorer Extension

An older tool for the same job is SVG Explorer Extension, a project by Tibold Kandrai with its source and installers on GitHub. Its installer files are named svg_see. Its project page describes it as an “extension module for Windows Explorer to render SVG thumbnails”.

What its own page says:

• Download the installer from the project’s Releases page on GitHub and run it. No further setup is needed.
• Pick the right one for your system. “The 32 bit installer will run on a 64 bit system, but the extension will not function.”
• If thumbnails do not show, open File Explorer Options and, under the View tab, make sure Always show icons, never thumbnails is unticked.
• If they still do not show, Windows may be holding old cached thumbnails. Open Disk Cleanup, tick Thumbnails, and click OK.

The latest release on that page is version 1.1.0, from May 2020, and the page describes thumbnails only, not the preview pane. PowerToys is maintained by Microsoft and its latest release is recent, so it is the better first choice on any computer that meets its requirements. There is no need for both.

Without installing anything

On a work computer where you cannot install software, there are still ways to look at an SVG:

• Drag it into a web browser. Every modern browser draws SVG.
• Open it in the SVG viewer. It shows the picture, the size and viewBox, and a count of what is inside, and the file is not uploaded. It opens one file at a time, so it does not replace thumbnails for a whole folder.
• Keep a PNG beside each SVG, as a picture of it that any image viewer opens. SVG to PNG makes one at any size. Files from our free SVG library each come with a PNG as well.

Questions

Does this change my SVG files? Nothing in Microsoft’s page or the extension’s describes the files being changed. Both describe drawing a preview or a thumbnail of the file, and the extension’s page speaks of Windows keeping thumbnails in a cache of its own.

Will thumbnails show the true colours and fonts? They show what the previewer draws. Text set in a font that is not installed falls back to another font, as it does anywhere an SVG is drawn. Converting text to paths in the drawing program avoids that.

What opens an SVG for editing? A vector editor such as Inkscape: open the file from inside the program. A web browser only shows it. What is an SVG file lists what opens one.

Does it work on Windows 7 or 8? Not with PowerToys, which needs Windows 10 version 2004 or newer.
