AVIF Converter

AVIF encoding runs through a WASM module (libavif) right in your browser — nothing gets uploaded. The first time you use it, the module (about 1–2 MB) needs to download and compile, which can take a few seconds.
Click or drag & drop an image (JPG, PNG, WebP)

Frequently asked questions

Do all browsers support AVIF?

All current versions of Chrome, Firefox, Edge, and Safari support AVIF. For very old browsers, it's worth keeping a JPG or WebP fallback.

Why does encoding take a few seconds?

The AVIF encoder (a WebAssembly module called libavif) downloads and compiles right in your browser the first time you use it — every conversion after that is faster.
