What is an AVIF file?
AVIF (AV1 Image File Format) is an image format from the Alliance for Open Media, a group that includes Google, Microsoft, Apple, Mozilla and Netflix. Version 1.0 of the specification came out in 2019. It stores images compressed with the AV1 video codec inside a HEIF container.
The appeal is size: AVIF can make photos noticeably smaller than JPG, and even WebP, at similar quality. It also supports transparency, HDR and wide color. That's why more and more websites serve images as AVIF, and why you may find .avif files in your downloads.

Why some apps can't open AVIF
Current versions of Chrome, Edge, Firefox and Safari all display AVIF, so images look fine on the web. Outside the browser, support is uneven. Older photo viewers and editors, office programs, messaging apps and many upload forms don't recognize the format.
On Windows, the Photos app needs the free AV1 Video Extension from the Microsoft Store to open AVIF files, and even then other programs may not. Converting to JPG is the reliable fix: the file opens everywhere, no add-ons needed.
Your browser is what decodes the AVIF here, so use an up-to-date version. If your browser can't read the file, the tool tells you rather than failing silently.
Quality, size and transparency
- Expect the JPG to be larger than the AVIF. AVIF compresses better; that's the trade-off for compatibility.
- High quality is the default and right for most images. Use Maximum for printing, or Medium / Smallest file when a form limits upload size.
- JPG can't be transparent. If your AVIF has a transparent background, the Transparent areas option fills it with White or Black. To keep the transparency, save the AVIF as a PNG instead.
- HDR images are converted to a standard JPG, so very bright highlights may look flatter.
Going the other way
Building a website and want smaller images rather than bigger ones? JPG and PNG files can become WebP, which nearly every browser supports: try making web-ready WebP images.
Frequently asked questions
Is my AVIF file uploaded?
No. It's decoded and saved as JPG on your device, inside your browser, and never uploaded. The page itself loads code, ads and cookieless analytics like any website; your files aren't part of that. Learn how to verify it.
What is an AVIF file?
An image in the AV1 Image File Format, released in 2019 by the Alliance for Open Media. It gives very small files at good quality, which is why websites use it, but many desktop apps can't open it yet.
How do I convert AVIF to JPG on Windows?
Open this page in Edge, Chrome or Firefox, drop the AVIF files on the box, click Convert, and download the JPGs. No Microsoft Store extensions are needed.
How can I open an AVIF file?
Any modern web browser opens AVIF: just drag the file into a browser window. To use it in other apps, convert it to JPG or PNG.
Is AVIF to JPEG the same thing?
Yes. JPEG and JPG are the same format; the files you download use the .jpg extension.
Why is the JPG bigger than my AVIF?
AVIF is a newer format with far more efficient compression. A JPG of the same image needs more bytes. Lower the Quality setting if the size matters.
What happens to a transparent AVIF?
JPG has no transparency, so transparent areas are filled with White by default, or Black if you choose it. Convert to PNG to keep the transparency.
Does the JPG keep the AVIF's EXIF data?
Not by default. Metadata is set to Remove, so camera details, location and dates are left out. Choose Keep to copy the EXIF and XMP data into the JPG.
