WebP offers smaller file sizes compared to PNG or JPG while maintaining similar quality. It's great for improving website loading speed.
The two real changes are that transparency disappears and the file gets much smaller. JPG has no alpha channel, so transparent areas are filled with white or your chosen background colour, and its lossy compression is great for photographs but leaves halos around text in logos and screenshots.
Yes — drop a HEIC file in and it is decoded in the browser and exported as JPG, PNG or WebP. Windows PCs and older software often refuse to open HEIC, so converting to JPG before you paste photos into a document or send them to a print shop removes the compatibility headache.
At the same visual quality AVIF is usually 20-30 % smaller than WebP, but it encodes more slowly and still fails to open in very old browsers and some in-app viewers. Pick AVIF when page speed is the priority and WebP when the file has to open reliably wherever you paste it.
