Frequently asked questions
How do I convert PNG to WebP?
PNG screenshots and design exports are often far larger than they need to be for the web — WebP's lossy mode typically holds visual quality close to the PNG source at a fraction of the file size, which is why most modern sites serve WebP instead of PNG for anything that doesn't need to be pixel-perfect.
Is this PNG to WebP converter free?
Yes — completely free with no signup, no watermarks, and no file limits. The tool is open source and will stay free.
Do my PNG files get uploaded to a server?
No. Conversion runs entirely in your browser using WebAssembly. Your PNG files never leave your device, which also makes it faster than upload-based converters.
Will converting PNG to WebP lose quality?
WebP is a lossy format, so some compression is applied — you control the trade-off with the quality slider (default 80%). At 85% or above the difference is rarely visible.
Can I convert multiple PNG files at once?
Yes. Drop as many PNG files as you like — they convert in batch and you can download the results individually or as a single ZIP.
Is this lossy or lossless WebP?
Lossy, controlled by the quality slider (default 80%). For screenshots and UI mockups with large flat-color areas, 80% or higher is usually indistinguishable from the PNG source at a fraction of the size.
