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.
Why this approach, and not AI-based removal
Modern AI inpainting tools can sometimes reconstruct a genuinely plausible guess at what was behind an object, but that technology works best on natural photos with lots of surrounding visual context to learn from, and it can introduce its own visible artifacts or outright invented detail that was never actually there. For a watermark - typically a stamp, logo, or repeated text sitting over otherwise unrelated content - a straightforward sample-and-blend or blur approach is both more predictable and more honest about what it's actually doing: covering the mark cleanly, not fabricating a guess at hidden content.
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.
Choosing between blend and blur
The blend mode works by sampling the colours immediately surrounding your marked box and generating a patch that matches that surrounding area, which looks genuinely seamless when the background is simple and consistent - a solid colour, a gentle gradient, plain paper. The blur mode instead heavily softens the marked area itself, which doesn't try to match the surroundings at all but reliably obscures the watermark's content regardless of how complex the background underneath happens to be, at the cost of leaving a visibly softened patch rather than an invisible one.
Why a single marked box applies across every page in a PDF
Many watermarks - a "DRAFT" stamp, a company logo, a confidentiality notice - sit in exactly the same position on every page of a document, since they're typically added by the same tool or process that generated the whole file. Marking the position once and applying that same coverage to every page saves you from repeating the same marking step for a potentially long document, while still working correctly for the common case where watermark placement is genuinely consistent throughout.
Who actually needs this, and why
Businesses covering an old "Draft" or "Sample" stamp on a document that's now finalized and ready for distribution. Photographers and designers removing a placeholder watermark from their own work before final delivery to a client who has already paid for the unwatermarked version. Anyone who's licensed a stock photo or document template and needs to remove a preview watermark that the license already entitles them to clear.
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.
Privacy
Your file is processed on our servers over an encrypted connection and deleted automatically after processing. There's no account required and no additional watermark added to the result.
What happens with a semi-transparent watermark
Many watermarks are deliberately semi-transparent, letting the content underneath partially show through - a common technique for stock photo previews and document drafts specifically meant to be replaced once licensed or finalized. Both the blend and blur approaches handle this the same way as a fully opaque watermark: they cover the entire marked box regardless of how transparent the original mark was, since the goal is making the watermark unobtrusive, not selectively treating different opacity levels differently.
Working with a repeated pattern watermark
Some documents use a repeated, tiled watermark pattern across the whole page rather than a single stamp in one spot - in that case, marking just one instance won't cover the others, since each repeat sits in a different position. For a tiled pattern like this, you'd need to mark each visible instance separately, which works fine for a handful of repeats but becomes impractical for a very dense pattern covering most of the page's visible area.
Checking your result before relying on it
After processing, it's worth a quick look to confirm the covered area blends in reasonably well at normal viewing size - a patch that looks slightly off up close is often completely unnoticeable once viewed at a normal distance or printed at typical size, so judge the result the way it will actually be seen rather than at maximum zoom level.
Redoing a box if the first attempt isn't quite right
If your first attempt at marking the watermark doesn't produce the result you expected - the box was slightly too small, or blur would have worked better than blend for that particular background - simply redo the process on the original file with an adjusted box or a different mode, since there's no limit on how many times you can reprocess the same source file while getting the final result exactly right for whatever you actually need it for.
