Open ConverterWebP typically produces files 25-35% smaller than PNG. That means faster page loads without visible quality loss.
Unlike JPEG, WebP supports alpha transparency just like PNG. Your transparent backgrounds stay transparent.
97% of browsers support WebP now, including Safari (since version 14). It's safe to use for most projects.
At 80% quality (our default), the difference is imperceptible. You can adjust the slider if you want more or less compression.
For the ~3% of users on older browsers, use the <picture> element to serve PNG as a fallback.
No. Everything happens in your browser using WebAssembly. Your files never leave your device.
