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.
