AVIF is an image format based on AV1 image coding. It can store photographs and graphics efficiently, including transparency and high-dynamic-range information in supported workflows. The practical problem is compatibility: a modern browser may open the file while an older editor, CMS, messaging app, or desktop workflow does not.
Do not rename .avif to .jpg
Changing the filename extension does not convert the encoded image. A program that checks the actual file contents will still see AVIF data. Use a real decoder and export a new file in the required format.
Choose the destination format deliberately
| Export | Use when | Tradeoff |
|---|---|---|
| JPG | Broad compatibility for photos | No transparency; lossy |
| PNG | Transparency or sharp graphics | Can be much larger for photos |
| WebP | Modern web workflow | Compatibility can still vary in older software |
Open and convert an AVIF in the browser
- Open File OpenerGo to Fitabyte File Opener and choose the AVIF file.
- Confirm the image rendersAVIF decoding depends on the browser. If the preview appears, the browser can read the file.
- Choose PNG, JPG, or WebPSelect the format accepted by the destination rather than the smallest format by default.
- Download a converted copyKeep the AVIF source separately so you can create a different export later.
If the converted JPG or PNG becomes too large for an upload limit, use Compress on the new copy. For format tradeoffs, see WebP vs JPG vs PNG.
