PNG to WebP Converter
Convert PNG images to WebP with transparency intact and dramatically smaller files — free, in your browser, no upload. Free to use right here — nothing to install, no account needed.
Convert PNG images to WebP without losing transparency. WebP supports alpha channels just like PNG but compresses far better — logos, UI screenshots and graphics often shrink by 50% or more, which makes a real difference to page load times.
Everything happens in your browser: drop the PNG in, download the WebP, and your image never touches a server.
Frequently asked questions
Does WebP keep PNG transparency?
Yes — WebP fully supports alpha transparency, unlike JPG. Transparent logos and icons convert cleanly.
Lossy or lossless WebP for PNG graphics?
For logos, icons and screenshots choose "WebP (Lossless)" — pixel-perfect and still much smaller than PNG. For photographic PNGs, lossy WebP at 85–90% quality is dramatically smaller.
How much smaller will my PNG get?
It varies with content, but 40–70% savings are common for graphics converted to lossless WebP, and more for photos converted to lossy WebP.
