You received an AVIF image, double-clicked it on your Windows PC, and instead of a photo you got an error or a blank icon. This is a common frustration. AVIF is a newer format, and while Windows is gradually adding support, many setups still cannot display it out of the box. The good news is that you have several reliable ways to open AVIF on Windows, from installing a codec to a quick conversion that works on any machine.

This guide covers every method, from the built-in options in Windows 10 and 11 to the foolproof fallback of converting the file. If you just want the image open right now without fiddling with system settings, the browser-based AVIF to JPG tool is the quickest route. Let us start with why Windows sometimes struggles.

Why Windows Sometimes Can't Open AVIF

Windows relies on installed codecs to decode image formats. JPEG and PNG support has been baked in for decades, but AVIF is recent enough that the decoder is not always present. On Windows 11 and recent Windows 10 builds, Microsoft offers an AV1 Video Extension that also enables AVIF images in the Photos app and File Explorer thumbnails. If that extension is missing, AVIF files will not display.

The situation is improving with each Windows update, but you cannot assume every PC has the codec. That is why a conversion fallback is valuable: it works regardless of what is or is not installed on a given machine. To understand the format itself, our overview of what is an AVIF file provides helpful background.

Method 1: Install the AV1 Video Extension

The official path to native AVIF support is Microsoft's AV1 Video Extension, available free from the Microsoft Store. Once installed, the Windows Photos app can open AVIF files directly and File Explorer can render thumbnails. This is the best option if you regularly receive AVIF images and want them to behave like any other photo.

Steps to install the codec

  1. Open the Microsoft Store. Search for AV1 Video Extension.
  2. Install the extension. Click Get or Install; it is a small, free download from Microsoft.
  3. Restart File Explorer or your PC. This ensures thumbnails refresh.
  4. Double-click an AVIF file. It should now open in the Photos app.

Note that this enables viewing, not necessarily editing. Many photo editors still will not import AVIF even with the codec installed, so for editing you will likely still need to convert.

Method 2: Open AVIF in Your Web Browser

Every modern browser on Windows, including Chrome, Edge, and Firefox, can display AVIF images natively. If you just need to see the picture, this is the fastest no-install option:

  1. Open a new browser tab. Use Chrome, Edge, or Firefox.
  2. Drag the AVIF file into the tab. The browser decodes and shows it instantly.
  3. Right-click to save or copy. You can save the displayed image in another format from some browsers.

This works because browsers ship their own AVIF decoders independent of the Windows codec. For details on which versions support it, see our guide to AVIF browser support.

Method 3: Convert AVIF to JPG (The Universal Fix)

The most reliable method, working on any Windows PC regardless of codecs or browser, is to convert the AVIF to a format Windows has always understood. Converting to JPG gives you a file that opens in Photos, Paint, Office, and every editor without any setup:

  1. Open the converter. Go to the AVIF to JPG tool in your browser.
  2. Add your AVIF file. Drag it in or browse to select it.
  3. Pick a quality setting. Around 85 percent keeps photos sharp.
  4. Convert and download. Save the JPG and open it in any Windows program.

Because the conversion runs in your browser, your image never uploads to a server, which keeps private photos private. If your image has transparency you need to keep, convert to PNG with the AVIF to PNG tool instead, since JPG cannot store transparent pixels. Our step-by-step how to convert AVIF to JPG guide explains the quality settings in detail.

Which Method Should You Choose?

Each approach suits a different need:

  • Install the codec if you frequently receive AVIF files and want them to open natively in Photos without conversion each time.
  • Use a browser when you only need a quick look and do not want to install anything.
  • Convert to JPG when you need to edit, share, upload, or print the image, or when you are on a locked-down PC where you cannot install software.

For most people who occasionally encounter an AVIF, conversion is the simplest answer because it produces a file that works everywhere, forever, with no dependency on what is installed. To decide between JPG, PNG, and WebP as your target, our AVIF vs JPEG comparison lays out the trade-offs.

Troubleshooting AVIF on Windows

If you installed the AV1 extension but AVIF still will not open, restart your PC to let the codec register fully. If thumbnails appear blank in File Explorer, clear the thumbnail cache via Disk Cleanup. If a specific editor refuses the file even with the codec present, that program simply has not added AVIF import support; convert the file first. And if an AVIF opens but looks washed out or colors are off, the original may use HDR or wide-gamut color that the viewer is not handling, in which case converting to JPG normalizes it.

Keeping AVIF for the Web, JPG for Everything Else

A practical workflow is to keep your AVIF originals for any website you run, since they load faster, while converting copies to JPG whenever you need to use the image in desktop software. This gives you the best of both worlds: lean files online and universal compatibility offline. If you later want to go the other direction and create AVIF files from your photos, the JPG to AVIF tool handles that, and our guide on converting JPG to AVIF explains when it is worth doing.

Conclusion

Opening AVIF on Windows comes down to three reliable options: install Microsoft's free AV1 Video Extension for native viewing, drag the file into any modern browser for a quick look, or convert it to JPG for guaranteed compatibility in every program. When in doubt, conversion is the universal fix that never depends on your system setup. Stuck with an AVIF that won't open? Head to the AVIF to JPG converter, drop in your file, and get an image Windows opens instantly.
