Converting a JPG photo to AVIF
This JPG to AVIF converter re-encodes a JPG photo as AVIF, a newer format that typically stores the same picture in noticeably less space. Choose a JPG, set the quality slider, and download the AVIF. Use JPG to AVIF when you are preparing images for a modern website and want smaller files without giving up much visible quality. It needs no installed software.
A good fit for modern websites
Choose AVIF output for web images viewed in current browsers, where AVIF support is now standard. Keep the JPG original as your master copy, since some older apps, editors and platforms still cannot open AVIF files when you need to share them elsewhere. That keeps one master file for every future use.
Good to know
AVIF encoding is done by your browser, and only browsers that support encoding AVIF can complete the conversion. If yours cannot, the tool shows a clear message explaining the limit instead of producing an empty or broken file. Try a small test image first.
Frequently asked questions
Why does the converter not work in my browser?
Writing AVIF files requires browser support for AVIF encoding, which not every browser has yet. Reading AVIF is more common than writing it. Try a current version of Chrome or Edge if you see the support message.
Will the AVIF look worse than my JPG?
AVIF re-encodes the pixels your JPG already has, so it cannot add detail back. At the default quality the result looks very close to the JPG while usually taking less space; lower quality shrinks it further.
Is my photo uploaded to a server?
No. Your JPG is encoded inside your browser and never sent to this site's server. The AVIF is created on your device, which suits personal photos and client work alike.

Limitations
AVIF encoding is only available in browsers that support it; otherwise a clear message explains the limit. Files are processed in your browser and never sent to the site's server.
