Frequently asked questions

Does WebP to PNG preserve transparency?

Yes — PNG supports full alpha transparency, so transparent WebP images convert cleanly. PNG is lossless, so no image quality is lost either; files just get larger, since PNG compresses less aggressively.

Why is my PNG bigger than the WebP was?

Expected: WebP is a newer, more efficient format. You’re trading file size for universal compatibility and losslessness. If size matters more than compatibility, keep WebP.

Are my images uploaded to a server?

No. Conversion runs entirely in your browser using its built-in image engine — files never leave your device, which also makes it faster than upload-based converters and safe for private photos.
