Take the stamp off.
Keep the document.

Unstamp finds the DRAFT, CONFIDENTIAL or SAMPLE mark on a scan, a PDF or a Word file, removes only that, and hands the file back in its own format.

Nothing is uploaded until you confirm. The confirmation is recorded with each upload; the file and its name are not.

No account. Your file goes into private storage that only this app can read, and is deleted once it has been processed. The cleaned file can be downloaded for one hour, and a daily sweep deletes it, with anything left unfinished, within about 26 hours. The models run inside this app. House rules

Our own test page. We stamped it, and the code that runs this site cleaned it. Not retouched. Drag to compare.

On a scan the stamp is part of the picture. That is the hard case, so we built for it.

Unstamp reads how far the stamp darkened the paper, measures its cover pixel by pixel, and reverses exactly that. Letters under the stamp keep their weight, and the rest of the page is not touched.

Remove a stamp from a scanned PDF

  1. Word

    The watermark is its own object in the file, so it is deleted outright. Your text stays text.

  2. PDF

    Watermark layers, annotations and repeated overlays are removed. Text and fonts are kept.

  3. Pictures

    The mark is found for you and the picture is restored under it. You see both versions before you download.

  4. Refused

    Stock agency marks and AI generator labels are read and refused, never removed. House rules

Before you upload

Which files does it take?

Word documents (.docx), PDFs with real text, scanned PDFs, and pictures (PNG, JPG, WebP, TIFF, BMP), up to 25 MB each. Every file comes back in the format it arrived in.

What does it remove?

The marks people put on their own paperwork: DRAFT, CONFIDENTIAL, SAMPLE, COPY, INTERNAL USE ONLY and the like, whether they sit in a Word header, a PDF layer, or across a scanned page. You can also type the exact phrase to remove.

What does it cost?

Nothing at the moment. Finding the mark, seeing the result and downloading the clean file are all free while Unstamp is being opened up.

Is my file kept?

Not for long. Your upload goes into private storage that only this app can read, and is deleted once it has been processed. The cleaned file can be downloaded for one hour, and a daily sweep deletes it, with anything left unfinished, within about 26 hours. The models run inside this app, and nothing is used for training.

Can I use this on a document that is not mine?

No. Unstamp is for documents you own or have permission to edit, and it asks you to confirm that before anything is processed. It refuses stock agency marks and AI generator labels outright.
