How do I convert WebP to AVIF?

Upload your WebP file above. It is converted to AVIF automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting WebP to AVIF lose quality?

AVIF is lossy by default, so some fine detail is discarded to make the file smaller. Raise the quality or switch on lossless in Settings for a closer copy.

Will the AVIF keep the transparent background?

Yes. AVIF supports smooth, partial transparency, so transparent areas stay transparent.

Will the animation be kept?

Non. Le format AVIF ne gère pas l’animation : un WebP animé est donc enregistré avec sa première image.
