Convert PNG to WebP
Cut image weight for faster websites: a WebP is usually much smaller than the PNG it came from.
What happens when you convert PNG to WebP
WebP applies modern compression that PNG's format, designed in 1996, cannot match. For the same visible image it commonly lands 30-70% smaller. Transparency is fully supported, so alpha channels come through intact — unlike JPG. This converter uses quality 0.92.
Good for
- Cutting page weight and improving Core Web Vitals on a website
- Storing large libraries of graphics without filling a disk
- Serving logos and UI assets that need transparency but not PNG's size
Worth knowing
- This is a lossy encode at quality 0.92. For pixel-exact archival masters, keep the PNG.
- Every current browser supports WebP, but some older desktop software and printers still do not open it.
- Very small images with few colours occasionally come out slightly larger than the PNG, since PNG is efficient for flat colour.
