JPG to AVIF Converter

Last reviewed: 2026-07-25

Convert a JPG input into a AVIF output - one step, in the browser. The picture is read and encoded on your device, so nothing is uploaded to a server.

Typical use: when your downstream platform accepts AVIF but not JPG.

Key features

Draws your JPG to an in-browser HTML5 canvas and encodes it to AVIF with a WebAssembly engine running on your device.
Returns the AVIF as a downloadable blob with no server round-trip.
Builds the preview link for the output entirely client-side.
Output sizing and quality are set from the option fields above the file picker; the defaults match the most common downstream use.

Privacy

The tool does not store your input or output beyond the page session and does not send your picture to any analytics or tracking service. No account or signup is needed.

Good to know

The encoder is single-threaded WebAssembly, so a very large image can take a few seconds; 10-bit and 12-bit HDR encoding are not offered. To convert to or from other formats such as PNG, JPG, or WebP, browse the image conversion tools hub.
