Why does it save as PNG rather than WebP?

To avoid a second lossy pass. WebP in, PNG out means the only compression your image has been through is the one it arrived with.

Does animated WebP work?

No. Only the first frame is read. This is a still-image editor.

Is WebP transparency preserved?

Yes. The alpha channel passes through untouched, and PNG carries it out.

The file will be bigger: is that expected?

Yes, PNG is lossless so it is larger than WebP. Re-encode it afterwards if size matters more than fidelity.

Remove a watermark from a WebP

Open a WebP image, paint out the watermark, and download the cleaned result as a lossless PNG at the original resolution.

The short version

WebP is what most modern sites serve, so it is often what you end up with after saving an image from the web. The editor decodes it natively and hands the result back as PNG, which avoids stacking a second round of lossy compression on top of the first.

How to do it

Drop the WebP file in.
Paint over the watermark.
Remove, and download as PNG.
