How to open AVIF files on Windows
By EditItAll · Updated
Convert the AVIF to JPG. Every Windows version opens JPG in Photos, File Explorer, and the browser. Some Windows 11 PCs already show AVIF in Photos. Many Windows 10 PCs do not, until optional codecs are installed, and those installs are easy to get wrong. A file that still will not open is not a corrupt photo.

Convert AVIF to JPGWhy Photos will not open the file
AVIF is a modern photo format. At similar quality it is smaller than JPEG, and desktop support is uneven. Some Windows 11 PCs open AVIF in the Photos app. Many Windows 10 PCs do not, until optional codecs are installed, and those installs are easy to get wrong.
If Photos, Paint, or File Explorer shows an icon or an error, the picture can still be fine. A file that still will not open is not a corrupt photo. Read the format notes on AVIF, then convert it to a format Windows already opens.
Convert AVIF to JPG
The durable fix is to convert AVIF to JPG. Every Windows version opens JPG. Open that page, drop the AVIF on the converter, and set the quality slider. You can also set an optional max-dimension cap if you want a smaller pixel size. There is no target-file-size field.
The results list shows the original size and the new size, each rounded to a whole KB. A readout of 20 KB can be 20.4 KB. Conversion runs entirely in your browser and works offline after the page loads. The file is processed right on your device. It is never uploaded. No account and no watermark.
When to use PNG instead
JPG is the file you send when the other person just needs to open the photo. AVIF to PNG keeps more detail and the file is larger. Use PNG for a graphic, a screenshot, or a photo you will edit again. Use JPG for email, chat, and older PCs.
Both converters use the same controls: a quality slider and an optional max-dimension cap. Drop the file on the exact convert page. The AVIF format page explains what the format is. It is not a drop zone.
What to do after the download
Save the JPG, then double-click it. Photos should open it on Windows 10 and Windows 11. If you still need the original AVIF, keep that file. The converter does not replace it.
- Open Convert AVIF to JPG.
- Drop the AVIF file on the page.
- Move the quality slider. Set a max dimension only if you want fewer pixels.
- Download the JPG and open it in Photos.
Skip optional codec installs when the goal is simply to see the picture. Codec packages are easy to pick wrong, and a file that still will not open afterward is still not a corrupt photo.
