What AVIF is and why you are seeing it
AVIF stores a still frame of the AV1 video codec in a HEIF container. Websites adopt it because it often beats WebP and JPG on file size, especially for photos with smooth gradients.
| Property | AVIF | JPG |
|---|---|---|
| Codec | AV1 intra-frame (2019) | JPEG (1992) |
| Compression | Lossy or lossless | Lossy |
| Typical size at similar quality | Often well below JPG and WebP | Baseline |
| Colour depth and HDR | 8, 10 or 12-bit, HDR capable | 8-bit, SDR |
| Transparency | Yes | No |
| Animation | Yes (image sequences) | No |
Compression gains depend strongly on the image and encoder settings.
Saved from websites
Image CDNs and frameworks increasingly send AVIF to browsers that accept it, so "Save image as" hands you an .avif file.
Exported by newer apps
Some cameras, phones and editors can export AVIF. The recipient may not be able to open it.
Converting a young format to the oldest one
AVIF is technically ahead of JPG in almost every way. You convert purely for compatibility, so keep the AVIF original if you can.
Convert for editors and office apps
Older image editors, document tools and many desktop viewers show an error or blank preview for AVIF.
Convert for uploads
Marketplaces, forms and older content systems often whitelist JPG, PNG and maybe WebP, but not AVIF.
Keep AVIF for your website
If you publish images, AVIF with a JPG or WebP fallback is the faster option. Don't replace it site-wide.
What the JPG copy can't carry
The visible picture converts cleanly. Features beyond what JPG supports are flattened.
HDR and 10/12-bit colour
The image is converted to 8-bit standard range. HDR highlights are tone-mapped by the browser's decoder and may look flatter.
Transparency
Transparent areas are filled with white or a colour you choose. Use a PNG output if you need the alpha channel.
Animation and file size
Animated AVIF becomes its first frame. And expect a larger file: JPG needs more bytes for the same look.
AVIF support in browsers and apps
All major browsers now decode AVIF. Beyond browsers, support is still arriving.
| Browser or app | AVIF | JPG |
|---|---|---|
| Chrome | Yes, from version 85 | Yes |
| Firefox | Yes, from version 93 | Yes |
| Safari | Yes, from 16.4 (with some limits on older macOS) | Yes |
| Edge | Yes, from version 121 | Yes |
| Windows Photos | With the AV1 Video Extension | Yes |
| Office, older editors, print services | Often no | Yes |
Support checked September 2026.
Why this page can read AVIF
Your browser's own AVIF decoder does the work, so conversion needs no extra download and nothing is uploaded.
Older browser?
If your browser predates AVIF support, the file won't decode here. Update the browser, then try again.
AVIF to JPG: questions
How do I open an AVIF file on Windows or Mac?
Modern browsers open AVIF directly. To use it in other apps, convert AVIF to JPG here and open the JPG anywhere.
Is AVIF better than JPG?
For file size and features, usually yes: AVIF supports HDR, transparency and more efficient compression. JPG wins on compatibility, which is why converting helps.
Will AVIF to JPG conversion make my images look worse?
At quality 85–90 the difference is minor, but HDR or wide-colour AVIFs are flattened to standard 8-bit JPG, which can look slightly less vivid.
Why is my JPG several times bigger than the AVIF?
AVIF's AV1-based compression is far more efficient than JPEG. Lower the quality slider if you need a smaller JPG.
Can I convert animated AVIF?
Only the first frame is converted to JPG. The animation is not preserved.
Does conversion keep the photo's EXIF data?
No. Metadata is stripped when the JPG is written, including location and capture date.
