Clean up PDFs privately, in your browser
Delete watermark objects, cover content on selected pages, and rebuild a document, all on your own device. Your file is not uploaded, and there is nothing to sign up for.
Three things this does
Watermark objects
Scan the file, see which watermark layers and annotation marks were found and why, then delete the ones you choose.
Remove a watermark →Content on a page
When a mark was drawn into the page itself, place a solid white box over it. The tool says plainly that this hides rather than deletes.
Open PDF whiteout →A fresh document
Copy every page into a brand-new PDF locally with MuPDF WebAssembly: the step that makes edit-restricted files workable.
Rebuild a PDF →How it works
- Choose a PDF. It is read straight into your browser's memory. There is no upload step, and nothing is kept after you close the tab.
- Read the scan. The tool lists the watermark objects it can prove are there: each entry names the actual object and says where the evidence came from. You decide what to remove.
- Download the result. Open it and check two things: the mark is gone, and your own content is intact. Every tool in this category can hand you a smaller file; only your eyes confirm the right change.
Where your file actually goes
- You choose a file on your device
- Your browser reads it the page's own code, already downloaded
- A PDF engine in the browser does the work pdf-lib, and MuPDF compiled to WebAssembly when a rebuild or preview is needed
- You download the result written by your browser, from memory
What it supports, and what it does not
| 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 |
Every tool on this site states its limits next to the tool itself, rather than in small print. If a watermark cannot be handled honestly, you will be told which kind it is and what the alternatives are: usually this guide explains why.
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
Does my PDF get uploaded?
No. The file is read into your browser's memory and processed there. There is no upload endpoint, no server-side processing and no stored copy. The page's Content-Security-Policy restricts it to loading files from this domain (that is what fetches the PDF engine when you ask for one) and blocks every other origin, so there is nowhere for a document to be sent. You can confirm it in your browser's developer tools: every request is a plain GET for one of the site's own files, and none of them carries your file.
Is an account required?
No. You never create an account, and nothing asks you for a password. Open the tool, choose a file, download the result. There is nothing to sign up for, and therefore no email address to collect.
Does this work offline?
Yes, once the page has loaded. The processing code is a normal part of the page. If you want to use it on a flight, load the page first, and if you plan to rebuild a protected file, trigger that once while online so the browser caches the PDF engine.
What PDF watermarks can be removed?
Watermark layers (a form object placed over the page by a typical 'add watermark' feature) and annotation watermarks such as stamps and free-text marks. These are deleted from the file, not hidden. Marks that were drawn directly into the page content are a different case: there is no separate object to delete, so the honest option is covering them.
Can it remove scanned-image watermarks?
Not currently, and the site will not pretend otherwise. When a stamp is part of a scanned image it exists only as pixels; removing it means guessing what was underneath. That is image inpainting, and nothing on this site does it.
Can I process encrypted PDFs?
Partly, and the distinction matters. If the file opens without a password but restricts editing (the permissions case, often called protected or locked), this site can rebuild it locally into a normal PDF and then work on it. If the file demands a password just to open, it is refused: that is access control, and this tool does not break it.
