Why Convert PNG to WebP?
WebP lossless mode produces files 26% smaller than PNG — and unlike JPG, WebP fully supports alpha transparency. Convert PNG to WebP to get smaller files for web use without sacrificing the transparent backgrounds your logos and UI assets require.
About PNG
PNG is the lossless standard for logos, icons, UI screenshots, and design exports. It supports full alpha transparency and preserves every pixel exactly, but produces larger files than modern formats.
About WebP
WebP supports both lossless and lossy compression plus full alpha transparency. WebP lossless files are 26% smaller than equivalent PNGs. All modern browsers support WebP natively, making it the best choice for web-served images.
