Convert JPG to AVIF
Turn JPG photos into AVIF and cut their weight by a third to a half without a visible difference. Drop your .jpg or .jpeg files below, check the live size, and download — the conversion runs in your browser and your photos are never uploaded.

The conversion pays off most on photographs you publish: product shots, blog images, portfolio pictures. These are the files that visitors download over and over, so a 40% saving repeats on every page view and shows up directly in loading time.
It pays off least on photos you only keep. An archive of holiday pictures gains little from a second lossy pass, and JPG still opens in every program ever written. Convert the copy you publish and keep the JPG original.
What to check before you replace your JPGs
Every current browser displays AVIF, but some older software does not: email clients, certain office suites and a few upload forms still expect JPG. If the picture is going anywhere other than a web page, test one file first.
Re-encoding a heavily compressed JPG can make its blocky artefacts more visible, because the new encoder treats them as detail worth keeping. If the source is already rough, raise the AVIF quality a little or start from a better original.
Frequently Asked Questions
For a typical photo, expect 30–50% less at a quality that looks the same. A 2 MB phone JPG usually lands between 1 MB and 1.4 MB, and much lower if you also reduce the dimensions.
No. The JPG has already discarded detail, and AVIF cannot bring it back. What you gain is file size: the same picture stored more efficiently.
AVIF numbers run lower than JPEG numbers for the same look. Around 55–65 matches a JPEG at 80–85. Start at 60 and compare with the before/after slider.
Creating AVIF files in the browser currently works in Chrome and Edge. Safari and Firefox can display AVIF but cannot encode it here, so switch to a Chromium browser for this conversion.
