AVIF or WebP: what should you compare?

Compare AVIF and WebP on the images you will publish. Check image quality and app support as well as file size.

Check	What to do
Visible quality	Compare edges, texture and gradients at the intended display size.
File size	Measure the actual exported files.
App support	Try the file in the app or website where it will be used.
Conversion cost	For a batch, measure processing time with the settings you intend to use.

Keep the comparison controlled

Use the same original, dimensions and intended color appearance. Do not assume that matching quality numbers produce matching results.

The examples list their export settings. Different images can give different results.
