Free online JPEG→AVIF converter. Fast, private, no sign-up.
Going from JPEG to AVIF takes a couple of clicks: drop the file in, download the result. Drop in your JPEG file (a .jpg) and download a ready-to-use AVIF file (a .avif) — no software to install, no account to create, and no watermark on the output.
JPEG is the workhorse of digital photography: a lossy format that shrinks photos by discarding detail the eye barely notices. It has no transparency and softens text and sharp edges, but for photographs it is unbeatably small and supported everywhere.
AVIF, based on the AV1 codec, delivers the smallest files of the mainstream formats at a given quality, with transparency and HDR — at the cost of slower encoding and slightly less universal support than WebP.
The usual reason to convert JPEG to AVIF is file size or quality: AVIF fits the job better, whether that means a smaller download, a cleaner edit, or broader support. Under the hood the conversion runs on libvips and ImageMagick — the same libraries that power image pipelines across the web — so colour, transparency and metadata are handled correctly wherever the target format supports them.
Unlike JPEG, AVIF supports transparency, so it's a good target if you later need a cut-out.
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Privacy is the default here. Your JPEG file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
