About These Formats
Converting PNG to WebP gives you everything PNG offers, full alpha transparency and lossless mode, while typically cutting file size by 25 to 50 percent. WebP supports a true alpha channel just like PNG, which means logos, icons, product cutouts, and UI screenshots remain crisp with no halo around transparent edges. The savings are largest on graphics with broad uniform color regions and gradients, which PNG compresses inefficiently using DEFLATE while WebP handles with smarter intra-frame prediction. Typical use cases include shrinking PNG sprite sheets used in web apps, optimising product images with transparent backgrounds for e-commerce, replacing oversized hero PNG illustrations on landing pages, and packing app icons for cross-platform PWAs. You can choose lossless WebP for graphics where every pixel must be exact, or lossy WebP at quality 90 to 95 for further size reductions that remain visually identical for most viewers. WeLoveConvert converts entirely in your browser, so even folder-sized PNG batches stay private and process without any server roundtrip. For best results on logos with gradients, prefer the lossless mode at default settings.
