Convert JPG to AVIF
The smallest files of any format browsers can show.
About this converter
JPG is the universal lossy photo format, supported by essentially every device and application ever made. AVIF is a modern AV1-based format with the best compression of the mainstream options.
An AVIF 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 AVIF 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 AVIF supported everywhere?
Every current web browser reads AVIF, but many desktop apps and phone photo apps still do not. It suits a website, and not a file you need to send to someone.
Do my JPG files get sent anywhere?
No. Everything happens on your own device, so your pictures never leave it.
