Remove watermark from PDF

Scan the file, see exactly which watermark objects were found and where the evidence comes from, then delete the ones you select. Nothing is uploaded, and nothing is kept.

What happens when you press the button

The tool reads the PDF's internal structure and looks in two specific places: the page resource dictionary, where an overlay watermark lives as a form object, and the page's annotation list, where stamps and free-text marks live. For every candidate it reports the object name, how many pages it appears on, and why it looks like a watermark. You tick the ones you want gone.

Then it deletes those objects from the file: the object is removed from the dictionary, and the drawing call is stripped out of the page content stream. That matters: a mark that is merely switched off is still in the file and still comes back when someone else opens it with different software. Deleting is not hiding.

What it can and cannot remove

Where the watermark lives	What this site does
Page overlay layer: a form object in the page's resource dictionary, added by an "add watermark" feature	Deletes the object
Annotation: a stamp, note or free-text mark placed on top of the page	Deletes the object
Drawn into the page content: raw drawing commands with no separate object	Cover only (PDF whiteout)
Inside the scanned image: a stamp on paper that was later scanned	Not supported
Protected file: opens without a password, but content is encrypted and editing is restricted	Rebuild locally first, then delete
Password-protected file: will not open without a password	Refused by design: no password cracking

If the tool finds nothing

That is a real answer, not a failure. Plenty of watermarks were never separate objects: a printer, a scanner or a report generator drew the mark straight into the page content. There is no object to delete, and no reliable way to tell such a mark apart from the text around it; a tool that "auto-detects" one usually either deletes your content along with it or does nothing at all. In that case this site points you at PDF whiteout instead, which covers the area you choose and tells you it did exactly that.

Edit-restricted files

If a PDF opens without a password but refuses to let you edit or copy, its page content is encrypted. Working on a file in that state produces garbage, so removal stays disabled until the document has been rebuilt locally into a normal PDF. Details are on the protected PDF page.

What this will never do is open a file you are locked out of. If a password is needed just to view the document, that is access control, and this tool does not break it.

Check the result yourself

A watermark removal tool can always hand you a smaller file. That proves something changed, not that the right thing changed. Open the download and confirm the mark is gone while your own text, tables and images are still there. The tool asks you to do the same thing when it hands you the file, because it is the only verification that counts.

Timing, measured in Chrome on a desktop: a 20 MB, 60-page file is scanned in 0.22 s and cleaned in 0.64 s; a 73 MB, 400-page file takes 1.2 s to scan and 2.4 s to clean. Time is rarely what stops you: memory is, because the peak is about three times the file size.

What this does not do. It does not remove a watermark that is part of a scanned image, and it does not guess. There is no OCR pass and no image inpainting here: those are different problems, and a tool that claims to solve them on any file is usually showing you a demo rather than your document. Covers on this site hide content visually; they do not make it unrecoverable.

Use it on documents you are entitled to change. Your own files, documents you have a licence to edit, material you have been given permission to modify. Removing someone else's copyright notice, or making a document look like it came from somewhere it did not, is not what this was built for.

Questions

Why does it ask me to tick boxes instead of removing everything it finds?

Because detection is evidence-based, not magic. Some candidates are certain: a form object literally named /Watermark, present on every page. Others are plausible but not certain, and deleting the wrong object can take page content with it. You see the evidence and decide.

Does removing a watermark break anything else in the file?

Only the objects you tick are touched; the rest of the page content stream is copied through unchanged. That said, always check the result: PDFs are produced by thousands of different tools, and a file that is already malformed can behave oddly no matter what edits are made.

Can it remove a watermark from every page at once?

Yes, and that is the usual case: an overlay watermark is typically the same form object reused across all pages, and the scan result says how many pages it appears on. Where several objects are listed, you can select all of them.

Do you keep the file or the result?

Neither. Nothing is uploaded, so there is nothing to keep. The result exists in your browser's memory until you download it, then it is gone when you close the tab.
