This tool stamps your chosen watermark text across every page of a PDF, with control over size, angle, and transparency, entirely in your browser.
How it works
- Add the contract PDF you want to mark.
- Choose the watermark text — DRAFT, COPY, CONFIDENTIAL, or your own wording.
- Adjust size, angle, and transparency so the text is visible without hiding the content.
- Download the watermarked PDF; keep your clean original separately.
Your privacy
Watermarking happens entirely in your browser — the document never leaves your device.
Nothing is uploaded, and nothing is stored after you close the tab.
Your documents are never used to train AI models.
Common use cases
- Mark an unsigned loan agreement as DRAFT while terms are still being discussed.
- Stamp COPY on duplicates so the signed original stays clearly identifiable.
- Label a contract CONFIDENTIAL before sharing it with an adviser.
- Add a recipient's name across a document so shared copies are traceable.
Limitations
- The watermark is stamped into the page content of the new file; keep the unmarked original if you will need a clean version later.
- A watermark is a label, not protection — it does not prevent copying or editing.
- Password-protected files must be unlocked first.
Frequently asked questions
Can a watermark be removed?
Someone with editing tools could reconstruct the page or crop around the text, so treat a watermark as clear labeling rather than security. It prevents honest confusion; it does not stop determined misuse.
Which watermark should I use for an unsigned agreement?
DRAFT is the convention. It tells everyone the terms are not final and stops a work-in-progress version from being mistaken for the signed contract.
Does a CONFIDENTIAL watermark make a document legally confidential?
No. Confidentiality comes from an agreement, such as an NDA, or from the relationship between the parties. The watermark communicates your expectation — it does not create a legal obligation by itself.
Will the watermark make the contract hard to read?
Not if you use the transparency control. A light, large, diagonal watermark is clearly visible while leaving the text underneath perfectly readable.
Should I watermark the signed original?
No — keep the signed original clean. Watermark the copies you send out, so the original remains the definitive version of the agreement.
