Convert AVIF to JPG
AVIF gives websites remarkable compression, and gives everyone else a file that will not open. This tool decodes AVIF with your browser and writes an ordinary JPG that Windows, macOS, Office, printers and upload forms all accept. Requires a browser that can display AVIF, which all current ones can.
How to use the AVIF to JPG
- Drop the .avif files you downloaded or were sent.
- Leave the quality at 90 unless you specifically need a smaller file.
- Choose a background colour if the AVIF has transparency, which JPG cannot store.
- Convert and download, one by one or as a ZIP.
What AVIF is
AVIF is a still image format built on the AV1 video codec, standardised by the Alliance for Open Media. It routinely beats JPEG by around 50% at matched quality and also beats WebP, which is why image-heavy sites adopted it quickly. It supports transparency, wide colour gamut and high dynamic range — capabilities JPEG simply does not have.
Why you might still need a JPG
Browser support is good: Chrome from version 85, Firefox from 93, Safari from 16.4 and Edge from 121 all decode AVIF. Everything else is slower. Many desktop photo editors need a plug-in, some office suites will not embed it, print shops and photo kiosks generally reject it, and a great many upload forms accept only JPG, JPEG and PNG. Converting to JPG trades file size for the ability to actually use the image.
How this tool decodes AVIF
There is no AVIF decoder shipped with this page. The file is handed to your browser's own image pipeline, exactly as if it were displayed on a web page, and the decoded pixels are then encoded as JPEG. That keeps the page small and the decode fast, but it means a browser that cannot display AVIF cannot convert it either. If you see a decoding error, open the page in an up-to-date Chrome, Edge, Firefox or Safari.
What changes
| Property | In the AVIF | In the JPG |
|---|---|---|
| File size | Reference | Usually 2–3× larger |
| Transparency | Supported | Flattened onto your chosen colour |
| Colour depth | Up to 12-bit, wide gamut | 8-bit sRGB |
| HDR | Supported | Tone-mapped by the browser to SDR |
| Metadata | EXIF/XMP possible | Not carried over |
Quality guidance
Because the source has already been compressed, keep the JPG quality at 85 or higher. Going lower adds JPEG blocking on top of the AVIF's own smoothing, and the two together look worse than either alone. If the resulting JPG is too large for what you need, compress it separately with a target size rather than dropping the quality here.
Frequently asked questions
Why does my browser say it cannot decode the AVIF?
The decoder belongs to the browser, not to this page. Use a current version of Chrome, Edge, Firefox, or Safari 16.4 and later.
Will the JPG be bigger than the AVIF?
Almost certainly — usually two to three times. AVIF compresses roughly twice as efficiently as JPEG at the same quality.
Does an AVIF with transparency convert cleanly?
The transparent areas are filled with the colour you choose, because JPEG has no alpha channel. Convert to PNG instead if you must keep transparency.
What happens to an HDR AVIF?
The browser tone-maps it to standard dynamic range while decoding, so the JPG will look flatter than the original on an HDR screen.
