Hold it to the light.See who leaked it.
Send the same document to everyone. Watermark makes every copy silently different, so a leak points to exactly one person.
Every copy carries a mark you can't see.
One document. Forty different files.
Upload the leak. Get a name.
Your deck, exactly as you sent it.
A watermark has proved where paper came from since 1282. Watermark proves where your file went.
You cannot stop someone from forwarding a file. You can make sure that forwarding it has their name on it.
Every recipient gets their own original
Same layout, same content, same file name. Underneath, no two copies are identical.
Marks survive the way leaks actually happen
Forwarded files, screenshots, printouts, and photos of a screen. Two independent layers today — one in the file, one in the pixels — so a forwarded file or a screenshot still carries a name. Photos and printouts go to assisted review.
Nothing changes about how you send
No portals, no login walls, no expiring links. Download the copies and send them however you already do.
Upload once
Drop in the PDF you were going to send anyway. Watermark never asks you to change the document.
Add your recipients
One name per line, or paste a list. Each line becomes a file that belongs to exactly one person.
Two layers go in
Per-copy identifiers in the PDF structure, and a sub-perceptual pixel pattern rendered into every page. Different leak paths destroy different marks, so the two are independent.
Find out whose copy it was
Upload the leaked file or a screenshot and you get a name back, usually in seconds. Photos of a screen and printouts go to assisted review, where we do the reading for you.

Security
Watermark exists because documents leak. Here is how we make sure we are never the weak link.
Marked, then forgotten
Originals are deleted after marking. Deleting a document destroys its identifier mapping for good.
No PII in your files
Each copy carries an opaque random identifier — never a name or an email. The mapping from identifier to person lives on our servers, and only you can query it.
Encrypted throughout
Files are encrypted in transit and at rest, and processed in isolated environments. Enterprise plans add private deployment and data residency.
Still unsure? Write to us — a human reads every message.
A tool that makes one uniquely marked copy of a document for every person you send it to. If the document leaks, the marks tell you whose copy it was.
Mark your first three documents free. No card, no portal, no change to how you send.
