How this works
There is no reliable way to detect an arbitrary watermark automatically, so you mark it once by drawing a box over it. We then paint over that same box - either by sampling the colour around it and blending a patch in (best for a logo or text stamp on a plain or lightly textured background), or by heavily blurring the area (safer for a busy photo, though the outline may still be faintly visible).
This is a practical "cover it up" approach, not content-aware inpainting - there is no way to reconstruct exactly what was behind the mark, only to make it unobtrusive.
Which tool should I use?
- PDF tool - for documents, invoices, certificates and scans. You mark the watermark once and the same area is covered on every page, which suits stamps or "DRAFT" text that sits in the same place throughout.
- Image tool - for a single JPG, PNG or WebP photo, screenshot or graphic, where you can choose between blending the area into its surroundings or blurring it.
Getting the cleanest result
Draw the box just slightly larger than the watermark itself. Results are best when the watermark sits on a plain or evenly coloured area such as a white page margin, a sky or a wall. Over detailed areas like faces, text or patterns, the covered patch will be more noticeable - blurring is often the better choice there.
Use it responsibly
Only remove watermarks from files you own or have permission to change - for example your own document with an old "Draft" stamp, or a photo you licensed. Removing a watermark to use someone else's copyrighted work without permission is not allowed.
