Can I make a separate watermarked copy for each person?

Yes. Paste the names, one per line, and use {name} in the watermark text, for example "Prepared for {name} · {date}". You get one PDF per person in a ZIP, plus a list of which file went to whom.

On top or behind the content?

On top is visible on every page and, with the blend mode used here, keeps the text underneath readable. Behind looks like Word's watermark and never covers anything, but it disappears on scanned pages, because a scan is one opaque picture.

Q: Can a watermark be removed?

A determined person with PDF editing software can remove a visible watermark. It deters casual sharing and shows where a copy came from, but it is not copy protection.

Stamp CONFIDENTIAL, DRAFT, your own text or a logo across a PDF, or make one personalised copy for every person you send it to.

One copy per recipient

Sending a document to several people? Paste their names, one per line, and put {name} in the watermark, for example "Prepared for {name} · {date}". Every person gets their own copy, the ZIP includes a list of who received which file, and if a copy turns up where it shouldn't, the watermark shows whose it was.

On top or behind

On top is drawn over everything with a multiply blend, so it tints the page instead of covering it, and text underneath stays readable. Behind is how Word places watermarks: under the text and pictures, so it never hides anything, but it is invisible on scanned pages, which are one opaque image.

Small files, any page layout

The watermark is stored once for each page size and reused on every page, so a 500-page PDF only grows by a few kilobytes. Rotated, landscape and mixed-size pages get an upright, centred watermark, and PDFs with editing restrictions are handled. Signed PDFs get a warning, because any change invalidates the signature.

Is my PDF uploaded?

No. The watermark is added in your browser tab and nothing is sent anywhere.
