About converting WebP to AVIF
WebP and AVIF both store a grid of pixels, so nothing is redrawn: the image is decoded once and written straight back out. What changes is how it is compressed, which is why the file size can move sharply in either direction. The quality setting is yours before you start.
How to convert WebP to AVIF
Add your WebP file
Drag it onto the box above, click to browse, or paste it straight from your clipboard.
Check the settings
AVIF is already selected. The defaults suit most files, and you can open Settings if you want to change the quality or size.
Download the AVIF
Most files are ready in a second or two. Larger ones convert in the background while you watch the progress.
