AVIF Converter
Convert images to AVIF, the next-gen format smaller than WebP.
Converts JPG, PNG, GIF, BMP, and most other image formats to AVIF directly in your browser using canvas encoding, with a quality slider to trade file size for visual fidelity. AVIF typically produces smaller files than WebP or JPEG at the same visual quality, making it a good choice for web performance in browsers that support it.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
Which browsers can encode AVIF?
Recent versions of Chrome, Edge, and Firefox support AVIF canvas encoding. If your browser doesn't, you'll see an error - try updating or switching browsers.
Is my image uploaded?
No - conversion happens entirely in your browser using the Canvas API.
Use this from your code
This tool is also a REST endpoint, so you can run it in a pipeline instead of by hand. Each call costs 2 credits and needs an API key. See the API reference for every parameter.
