Does converting PNG to WebP lose quality?

It depends on the mode. WebP lossless mode preserves every pixel exactly — zero quality loss, but still 26% smaller than PNG. WebP lossy mode at 80% quality is visually identical to the original for photos but cuts file size by 70–80%.

Does WebP support transparency like PNG?

Yes. WebP fully supports alpha channel transparency. Your transparent PNG will convert to a transparent WebP with the same sharp edges and full alpha support.

Will WebP work on all browsers?

All modern browsers — Chrome, Firefox, Safari (since 2020), Edge, and mobile browsers — support WebP. The only gap is very old versions of Internet Explorer.

Can I convert multiple PNGs to WebP at once?

Yes. FileCrisp accepts multiple files in a single batch. Drop all your PNGs, set the format to WebP, and download all converted files as a ZIP.

Can I convert WebP back to PNG?

Yes. FileCrisp converts in both directions — PNG to WebP and WebP to PNG. Just select PNG as the output format.

Is PNG to WebP conversion free?

Completely free. No account, no daily limit, no file size cap. FileCrisp processes everything locally in your browser.
