Guides
JPG, PNG or WebP?
JPG is the most compatible and lightweight for photos. PNG keeps transparency and is better for logos and screenshots. WebP is the smallest of the three and works in browsers and most apps.
Saved an image as WebP?
Many websites serve images as WebP, which some programs can’t open. Convert them to JPG or PNG here.
