Convert AVIF to JPG
AVIF in, JPG out, in a second or two — processed on your device, nothing uploaded.
Output format
What this tool does
It decodes your AVIF file and re-encodes the pixels as JPG at the quality you choose (92% by default — visually identical for photos). Your browser decodes AVIF natively (Chrome, Firefox and Safari 16.4+ all do), so no extra download is needed. The file is read, converted and offered back as a download without touching the network.
About AVIF
AVIF is the newest mainstream web format (2019), built on the AV1 video codec by the Alliance for Open Media. It compresses even harder than WebP — often half the size of JPEG — with transparency, HDR and wide colour, and is royalty-free. It is good for websites that want the smallest possible images and can serve fallbacks; less good for anything that leaves the web: most desktop programs, printers, e-mail clients and upload forms still do not recognise it, and encoding it is slow. Chrome 85+, Firefox 93+ and Safari 16.4+ display it; support outside browsers is still thin in 2026.
About JPG
JPEG (files end in .jpg or .jpeg — they are the same thing) is the 1992 lossy photo format that every camera, phone and website understands. It throws away detail the eye is bad at seeing, which is why a photo can be 10× smaller than as PNG while looking identical at normal viewing sizes. It is good for photographs and anything photo-like, email attachments, marketplaces and forms that demand .jpg, and situations where compatibility matters more than anything; less good for text, line art, screenshots and logos (the compression smears sharp edges into visible "ringing"), and anything that needs transparency — JPEG has none. Universal, and the safest choice when a form, portal or older program insists on a specific format.
What changes going from AVIF to JPG
- Transparency is lost. JPG has no alpha channel, so transparent areas are filled with white. If that matters, convert to PNG or WebP instead.
- Animation is dropped. JPG is a still format; you get the first frame.
- Quality: JPG is lossy. At the default 92% nothing is visible; lower the slider for smaller files.
- Size: Roughly 50% smaller than JPEG and 20% smaller than WebP at matched quality vs. typically 100 KB–4 MB for a phone photo depending on quality; re-saving a JPEG loses a little more quality each time.
- Metadata: EXIF (camera, date, GPS) is not carried over — the browser decodes pixels, not tags. That is a privacy plus for sharing and a minus if you rely on dates in the file.
Why AVIF files end up on your disk
Because modern sites serve AVIF to modern browsers, and "Save image as…" gives you whatever was served. JPEG is the compatibility target: much larger, accepted everywhere. Transparency becomes white. Your browser decodes the AVIF itself — this needs Chrome 85+, Firefox 93+ or Safari 16.4+.

Frequently asked questions
Is my AVIF file uploaded?
No. The page is static and has no upload endpoint; your browser does the work on your own device and the result is saved straight back to your disk. The site's Content-Security-Policy only allows it to talk to its own origin, so it cannot send your file anywhere even by accident. Load the page, disconnect from the internet, and it still works.
Does AVIF to JPG lose quality?
JPG is a lossy format, so strictly yes — but at the default 92% quality the difference from the AVIF is invisible at normal viewing size. Lower the slider only if you need a smaller file.
Will transparency survive?
No — JPG cannot store transparency. Transparent pixels become white. Use PNG or WebP as the target if you need it.
Is it free? Any limits or watermark?
Free, no account, no watermark, no daily quota. Because nothing runs on our servers there is nothing to meter. The only limits are your device's memory — anything up to roughly 50 megapixels is fine on a modern phone or laptop.
Can I do several files at once?
One file at a time at the moment — drop the next one as soon as you have downloaded the first. Batch processing with a ZIP in and out is planned.
Does it work on my phone?
Yes — iPhone, iPad and Android browsers all run it. AVIF decoding needs Safari 16.4+ or any recent Chrome/Firefox. Large files take a few seconds longer on a phone than on a laptop.
