AVIF is increasingly used by websites to keep images small. Saving one gives you an .avif file that current browsers display but that many photo viewers, editors, office programs and upload forms still reject. Converting to JPG trades some file size for compatibility.
Why AVIF files can be hard to use
How the conversion works
Your browser decodes the AVIF into pixels, and the converter writes those pixels as a JPG at quality 0.9. Two consequences follow:
- If your browser cannot display AVIF, it cannot decode it either, and the file will show an error. Current Chrome, Edge, Firefox and Safari can; older versions may not.
- Transparency is lost, because JPG has none. Transparent areas become white. For images that need it, convert to PNG with the WebP to PNG page, which accepts AVIF too.
Expect the JPG to be larger than the AVIF. That is normal: AVIF is the more efficient format.
Settings and output
- Quality: JPG is written at quality 0.9 where the format uses a quality setting. There is no slider on converter pages; use the Image Compressor if you want to choose the quality yourself.
- Size limits: images longer than 4096 px on either side are scaled down to 4096 px. If a converted file would be over 10 MB, it is reduced in steps until it fits.
- Batches: add several files; three are converted at a time. One file downloads directly, two or more come as a ZIP.
- Metadata: EXIF data (camera, date, GPS) and colour profiles are not carried into the new file.
Where the processing happens
Decoding and encoding happen in your browser; files are not uploaded.
Questions about this tool
I downloaded an .avif file and nothing will open it. How do I fix that?
Add it here, press Convert Images and download the JPG. JPG opens in any photo viewer, editor or upload form.
Why does my AVIF file show an error?
Your browser could not read the AVIF. The tool relies on the browser to decode it. Update your browser, or try current Chrome, Edge, Firefox or Safari.
Why is the JPG larger than the AVIF?
AVIF is a more efficient format, so the same picture needs fewer bytes. The JPG is larger but works everywhere.
My AVIF had a transparent background. What happens to it?
It becomes white, because JPG has no transparency. To keep it, convert with WebP to PNG, which accepts AVIF files too.
Can I convert many files at once?
Yes. Add several files and press Convert Images once. Three are converted at the same time. Download All gives you one ZIP file, or you can download each file on its own.
