Drop AVIF files here to convert to JPG
AVIF in, JPG out — up to 20 files, 50.00 MB each. Nothing is uploaded. Transparent areas are filled with white, because JPG has no alpha channel.
Why AVIF files are hard to open
AVIF is built on the same codec as AV1 video and is the most efficient image format in wide use: the same picture is typically about half the size of a JPG, and still smaller than WebP. Browsers have handled it for years, but the rest of the software world has not caught up — desktop photo editors, office documents, chat apps and upload fields routinely refuse an .avif file.
This converter works in your browser, so the image is never sent anywhere. Everything runs on the device you are already using, which is also why it is instant: no upload, no queue, and no second download of a processed copy.
AVIF or JPG: what you gain and lose

Where it wins
AVIF
The smallest files and it keeps transparency — ideal when you deliver the images yourself.
JPG
Accepted everywhere. Larger files and no transparency, but it opens in anything.
Frequently asked questions
Which browsers can decode the AVIF files I drop in?
Chrome 85+, Edge 85+, Firefox 93+ and Safari 16.4+. Older browsers cannot decode AVIF at all — if yours is one of them, the tool says so plainly instead of producing a broken file.
Does the quality change?
AVIF is already lossy, so the picture is re-encoded a second time. At the default 90% the difference is not visible at normal viewing size; use 100% for images with fine detail or small text.
What happens to transparent AVIF images?
AVIF supports transparency and JPG does not, so transparent areas are filled with white before the file is written. A cut-out subject therefore gets a white backdrop. Use a PNG if the alpha channel has to survive.
Will the JPG be bigger than the AVIF was?
Almost always, often two to four times bigger. AVIF compresses far more efficiently than JPG. The reason to convert is compatibility, not file size.
Are my images uploaded to a server?
No. Your browser decodes the AVIF and re-encodes it as JPG inside a Web Worker on your own device. There is no upload step, so no copy of the image exists on our side.
Can I convert several AVIF files at once?
Yes — up to 20 files per run, each up to 50 MB, processed one after another on your device.
