Universal compatibility
JPG opens in every browser, editor, CMS, email client and print service on earth, so an AVIF that a legacy tool refused becomes a file that simply works.

Overview
About the AVIF to JPG Converter
Convert AVIF to JPG free online — turn a modern AV1 image into a compact, universally supported JPG with a flatten colour and quality slider. Batch, no upload.
When a modern format meets old software
AVIF is the most efficient mainstream image format today, but efficiency does not help if the program you need to open it in was released before AVIF existed. Print bureaux, older desktop editors, some content management systems and plenty of upload validators still expect JPEG. Converting AVIF to JPG bridges that gap with the one format literally everything can read.
The flatten decision and the quality slider
Two things define the output. First, JPG has no transparency, so if the AVIF carried an alpha channel you choose what it flattens onto — white, black or light grey. Second, the quality slider decides how aggressively the JPEG compresses; because the source is already lossy, keeping it at 90% or above avoids stacking visible artefacts while still producing a small file. The result is a compact photograph that opens anywhere.
Batch conversion, privately
Up to twenty files convert in one run, each up to 25 MB, processed one at a time so memory stays predictable, with a summary strip totalling size before and after. Each result is named after its source with a .jpg extension. Nothing is uploaded: the decode, the re-encode and every download happen inside the tab, with no account and no watermark, because there is no server on the other end.
Step by step
How to use the AVIF to JPG Converter
Drop one or more images onto the upload area — an .avif or any other format, which is detected automatically.
Set the quality slider; 90% and above stays visually close to the decoded AVIF.
Choose what transparent pixels flatten onto, since JPG has no alpha channel.
Press Convert to JPG — each file is decoded and re-encoded locally, one at a time.
Read the result row for the size change, then download each JPG or the whole batch.
Why use it
Benefits and common use cases
What this tool is good for, and what it deliberately does not try to do.
Stays compact
JPG keeps the file small, which matters when the AVIF is going somewhere with an upload limit or into a page where bytes affect load time.
You choose the flatten colour
Because JPG has no transparency, any alpha in the AVIF is composited onto a colour you pick — white, black or grey — so the backdrop is never a surprise.
Private by construction
The decode and re-encode run in the browser's own image pipeline, so nothing is uploaded and no copy is stored.
Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
Why convert AVIF to JPG instead of PNG?
When the goal is a small, universally openable photograph, JPG is the better target. PNG would be lossless but several times larger. Choose PNG instead only if you need transparency or bit-exact pixels for further editing.
Is converting AVIF to JPG lossy?
Yes. AVIF is already a lossy format, and JPG applies its own compression at the quality you set. At 90% and above the added loss is very hard to see; keeping the slider high avoids compounding the two codecs' artefacts.
What happens to transparency?
JPG has no alpha channel, so any transparent areas in the AVIF are flattened onto the colour you choose. Pick white for a normal page background or black for a dark one; the rest of the image is unchanged.
Can every browser decode AVIF?
Chrome, Edge, Firefox and Safari 16 and later decode AVIF natively, which covers nearly all current users. On a much older browser that cannot, the file fails to decode and the result row reports it rather than producing a broken JPG.
Are my files uploaded to a server?
Never. There is no upload endpoint. The decode, the re-encode and every download happen inside your tab, and each result uses a local object URL released shortly after the click.
