WebP to AVIF
Drop in a WebP and download an AVIF. AVIF typically produces files 20–40% smaller than WebP at the same visual quality, with excellent support for transparency and HDR. Note: AVIF encoding via Canvas requires a recent Chromium-based browser (Chrome 85+, Edge 121+, Opera 71+). Firefox and Safari can decode AVIF but cannot encode it via Canvas — try Chrome if you hit an error. Conversion runs locally in your browser — files never leave your device.
