How to convert WEBP to AVIF

  1. Add your .WEBP file - drop it in the box above or click to browse.
  2. Convert it to .AVIF in a few seconds.
  3. Download your new .AVIF file.

What to expect

  • WebP uses the VP8 codec and AVIF uses AV1 - they are fully re-encoded, not rewrapped; a second lossy encode adds visible artifacts if the source .webp is already lossy.
  • Transparency is preserved: both formats support an alpha channel, so transparent .webp images convert to transparent .avif correctly.
  • Animated .webp files are not supported by most converters - only the first frame is typically exported.

Frequently asked questions

Does converting WebP to AVIF lose quality?
If your source .webp is lossy, re-encoding to AVIF adds another round of compression loss. Use high quality settings (75-90) to minimize visible degradation.
Is AVIF smaller than WebP?
Usually yes - AVIF typically achieves 20-50% smaller file sizes than WebP at similar visual quality, though exact savings depend on image content and settings.
Can I convert animated WebP to AVIF?
Most converters export only the first frame of an animated .webp. Full animated AVIF conversion requires advanced tools like ffmpeg with libaom.
Do all browsers support AVIF?
AVIF is supported in Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+. For older browsers or non-browser apps, .webp remains the safer choice.
