About the PNG to WebP Converter

WebP supports transparency, so an alpha channel survives the conversion intact - usually at a fraction of the PNG size.

For logos and screenshots, lossless WebP is typically 25% smaller than PNG; for photographs the saving is far larger.

Conversion happens entirely in your browser through the canvas API, so the image never leaves your device and the result appears as fast as your machine can decode and re-encode it.

Questions people ask

Is my image uploaded anywhere?

No. The image is decoded, processed and re-encoded by your own browser using the canvas API. You can watch the network panel while it runs, or disconnect from the internet after the page loads - the tool keeps working.

Is your image uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your image never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
