How to convert AVIF to JPG
Drop your AVIF image onto the box above, or click to choose one. The tool shows the original size and dimensions, converts in your browser, and shows the JPG size before you download. There is no upload, no queue and no account. If your browser is current, the whole job takes a second or two, because AVIF decoding is built into the browser itself.
Why AVIF files keep causing trouble
AVIF is one of the best image formats ever shipped: at the same visual quality it is routinely a third smaller than JPG, with better handling of gradients and dark scenes. Websites adopted it quickly to speed up pages, and some phones and screen capture tools now save in it too. The problem is the long tail of everything else. Older photo editors, office suites, content systems, printers, ID and application portals, and plenty of Windows software either never added AVIF support or hide it behind a paid codec. So files saved from the web or exported from new tools bounce off the systems people actually have to submit them to, and the fix that always works is converting back to JPG, the one image format every device and form on earth accepts.
How the conversion works
Unlike HEIC, AVIF decoding is now built into every major browser, so no heavy decoder download is needed. Your browser reads the AVIF file into pixels, this tool paints those pixels onto a canvas over a white background (JPG has no transparency, so see through areas need a base), and encodes the canvas as JPG at 92 percent quality, a level where photos show no visible difference from the original. Metadata such as camera details and location tags does not carry across the re-encode, which is a small privacy bonus when sharing images publicly. All of it happens locally: the image is never uploaded to a server.
Quality tips for AVIF to JPG
- Expect the JPG to be bigger. AVIF's whole advantage is efficiency, so the same picture as JPG commonly weighs 30 to 50 percent more. That is normal, not a failed conversion.
- Convert from the AVIF original each time. Repeated lossy conversions stack up damage; always start from the best copy you have.
- Keep the AVIF for your own website. If the file is yours and your site supports it, AVIF is the faster choice there; convert only the copies headed for forms, email and other people's software.
- Check anything with fine text. JPG softens sharp edges slightly. Screenshots and diagrams survive well at this quality, but zoom into the preview if every letter matters, and consider PNG via the Image Converter for those.
A worked example
A shop owner downloads her product photos from her own website to send to a marketplace, and finds they are AVIF files the marketplace upload form rejects with a plain "invalid format" error. She converts each one here in seconds, uploads the JPGs without a fight, and keeps the AVIF versions live on her own site where they load fastest. One format for her website's speed, one for everyone else's compatibility, and no photos uploaded to a conversion server in between.
