About this tool

AVIF to WebP keeps an image web-friendly and compact while widening where it can be used. WebP is supported by every current browser and far more apps, CMSs and upload tools than AVIF, while still compressing much better than JPG or PNG. It is the practical middle ground when an AVIF is rejected somewhere. Files usually come out somewhat larger, the price of wider support. Both formats are lossy, so convert from the original each time rather than back and forth, and transparency carries over.

How to use this tool

  2. Convert to WebPEach AVIF is re-encoded once as WebP, keeping transparency.
  3. Upload the WebPsDownload them and upload to the platform that rejected the AVIF.

Choosing WebP over AVIF

AVIF usually produces smaller files at the same quality, but encoding and support lag behind. WebP has been supported across browsers for longer and is accepted by most website builders and social tools. Converting a single image adds a small amount of compression loss, so convert from the AVIF once rather than repeatedly.
