Convert AVIF to JPG without installing anything
AVIF files are everywhere now: websites send them to save bandwidth, and when you right-click and save an image you often end up with a .avif file that your photo viewer, Word document or upload form refuses. This converter turns it into a standard JPG in a few seconds.
The conversion uses your browser’s own AVIF decoder and its JPG encoder. According to caniuse.com, AVIF is fully supported in Chrome 85+, Firefox 93+, Safari 16.4+ and Edge 121+. To learn more about the format itself, read What is an AVIF file?. Because no server is involved, it is fast even for a batch of files, and private by design.
Quality and background settings
- Quality (50–100%, default 92%) controls JPG compression. At 92% compression is hard to see on photos. Go down to 80% for smaller files to email; go up to 100% only if you plan to edit the image again.
- Background for transparent areas matters for logos, stickers and icons saved as AVIF with transparency. JPG cannot store transparency, so those pixels are filled with this color. Pick a color that matches where the image will appear.
When you convert several files, each gets the same settings and you receive a single ZIP containing every JPG with its original name.
AVIF vs. JPG at a glance
| AVIF | JPG | |
|---|---|---|
| File size at similar quality | Smaller | Larger |
| Transparency | Yes | No |
| HDR | Yes | Not in a standard JPG |
| Opens in every app | Not yet | Yes |
| Best for | Websites | Sharing, printing, editing |
If you need transparency kept, convert to PNG — for WebP files see WebP to PNG. For iPhone photos, use HEIC to JPG; for WebP images saved from the web, use WebP to JPG.
Troubleshooting
- “This browser can’t read” message: your browser is too old to decode AVIF (for example Safari before 16.4, or Edge before 121). Update it, or try the latest Chrome or Firefox.
- Animated AVIF: only the first frame is converted, because JPG is a still-image format.
- Colors look slightly different: HDR or wide-gamut AVIF images are drawn on a standard canvas before being saved as JPG, so very bright or saturated colors can look a little flatter.
What the JPG keeps and what it drops
The converter keeps the full pixel size of the AVIF: a 2400 × 1600 image comes out as a 2400 × 1600 JPG, never resized. What it does not copy is metadata. The image is redrawn on a canvas and saved by the browser’s JPG encoder, so EXIF data such as the camera model, date taken or GPS position is not carried over. Images downloaded from websites rarely contain any, but AVIF photos exported from a camera app or editor may. If you need the date or location kept, write it down with the EXIF Viewer before converting.
After converting, you can shrink the JPG further with Compress Image or check its dimensions with Check Image Size.
