Frequently asked questions

Does PNG to WebP preserve transparency?

Yes. Transparent pixels are preserved when the browser can decode and encode the image correctly.

Is the PNG sent to a server?

No. Conversion runs locally in your browser.

Will WebP always be smaller than PNG?

Not always. WebP is often smaller, but output size depends on image content and browser encoding.
