Convert PNG to WebP
PNG is the go-to format for crisp graphics, logos, and screenshots, but its DEFLATE compression leaves room for improvement. WebP matches PNG transparency pixel-for-pixel while shaving 20-30% off the file size. For lossless conversion — where every pixel stays identical — the savings come purely from better compression of the same RGBA data.
Usage Scenarios
- Replacing oversized PNG logos and icons on high-traffic landing pages
- Optimising sprite sheets — fewer bytes means fewer network round-trips
- Screenshots with large uniform areas compress exceptionally well in lossless WebP
- UI mockups delivered to clients where every kilobyte affects download willingness
Tips
- ▸For sharp-edged graphics like logos and icons, lossless WebP is pixel-identical to PNG but smaller
- ▸Lossy WebP with alpha quality set to 100 gives even more savings while keeping transparency crisp
- ▸If the PNG is already optimised (e.g. through pngcrush), lossless WebP still saves 15-20% on top
