When to use what

WebP for the web
Photos and banners on a site or e-shop. Noticeably smaller than JPG at the same look.
PNG for logos and screenshots
Keeps sharp edges and transparency. Not for photos, the file gets large.
JPG for email and print shops
Opens everywhere. No transparency, so flatten the background first.
AVIF when size matters most
Smallest files. Check that the destination accepts it, older tools may not.

Conversion runs in your browser. Files never leave your computer.
