Convert AVIF to WebP
Roughly a third smaller than JPG at the same quality.
About this converter
AVIF is a modern AV1-based format with the best compression of the mainstream options. WebP is Google's format offering roughly 25-35% smaller files than JPG at comparable quality, with transparency and animation support.
A WebP is for delivering a picture rather than keeping it: it is what a website serves to a visitor, and what an app bundles.
Frequently asked questions
Will converting to WebP reduce the image quality?
A little, in exchange for a much smaller file. The conversion runs at a high setting where most people cannot tell it apart from the original. If it is the file size you care about, Compress Images lets you name the size you want.
Is WebP supported everywhere?
Every current web browser reads WebP, as do Windows, macOS and recent Android. Older software and some phone photo apps still refuse it.
Do my AVIF files get sent anywhere?
No. Everything happens on your own device, so your pictures never leave it.
