Frequently Asked Questions

Why convert PNG to WebP?
WebP with lossless compression produces files 26% smaller than PNG on average, while lossy WebP can be 50-80% smaller. This dramatically improves web page load times.
Does WebP support transparency like PNG?
Yes, WebP supports both lossy and lossless compression with alpha channel (transparency). You get the same visual result with a smaller file.
Is my data private during conversion?
Yes. All conversion happens in your browser using WebAssembly. Your files never leave your device and we have zero access to them.
Will I lose quality converting PNG to WebP?
Not necessarily. WebP supports lossless compression that preserves exact quality while reducing file size. Even lossy WebP is often visually indistinguishable from the original PNG.
What browsers support WebP?
All modern browsers support WebP: Chrome, Firefox, Edge, Safari (14+), and Opera. Global support exceeds 97%.
