Convert to WebP — smaller files, faster pages
Every current browser supports WebP. It is about 25-35% smaller than JPEG at the same quality and dramatically smaller than PNG for images with transparency, which makes it an easy win for Core Web Vitals. Upload several files and convert them all in one pass — or, if you want the smallest result possible, convert to AVIF instead, which goes smaller still.
- Keeps PNG alpha transparency fully intact
- Animated GIF converts to animated WebP
- AVIF available when you need the smallest possible file

Frequently asked questions
WebP or AVIF — which should I choose?
AVIF makes smaller files but encodes more slowly. Use WebP as the safe default, and reach for AVIF when file size matters more than anything else.
