Questions and answers
How do I add a watermark to a PDF for free?
Drop your PDF into the tool at the top of this page, type the watermark text, set the opacity and download. It’s free, with no sign-up.
Where does the watermark go on the page?
In the center of every page, or tiled across the whole page. You choose the angle, the font and colour, and the opacity slider decides how strong it looks.
Will the watermark cover my text?
It sits on top of the page at the opacity you choose. Around 20–30% keeps the text underneath easy to read.
Can I use an image or logo as the watermark?
Yes. Choose Image as the watermark type and pick a PNG or JPG, such as your logo. It’s placed in the center or tiled, with the same angle and opacity controls.
Can I remove the watermark later?
The watermark is drawn into the page, so it can’t be switched off like a layer. Keep your original file if you might need a clean copy.
Can I watermark a password-protected PDF?
Yes, if you know the password. Pagestro asks for it and opens the file in memory. The stamped copy has no password, so run it through Protect PDF if it needs one.
Is my PDF uploaded?
No. The watermark is added by your browser on your own device, so the file is never sent to Pagestro.

What you get
A clear mark, without the fuss
Stamped on your device
Your browser draws the watermark into the PDF. Drafts, offers and private records are never uploaded.
Any words you need
DRAFT, SAMPLE, COPY, a client name or a date.
Readable underneath
Set the opacity low and the page text stays easy to read.
Works on your phone
Stamp a file from your mail app without waiting for a laptop.
Text stays text
The stamp sits on top. Words underneath can still be searched and copied.
Password-protected files
Enter the password and the file opens in memory first. The stamped copy has no password.
Free to use, as often as you like
No sign-up and no daily limit. Pagestro never adds its own logo to your pages.
Private by design
Mark the draft before it leaves you
A watermark matters most on the files you’d rather not upload anywhere: a contract still in review, a salary offer, a set of proofs. Pagestro adds the stamp inside your browser, so the only copy is the one you download.
- No upload and no server copy
- The same stamp on every page, in one go
- Close the tab and nothing is left behind
On the go
Stamp a PDF from your phone
Someone asks for the draft while you’re out. Open Pagestro in your phone’s browser, type DRAFT, and send back a marked copy in a minute.
- Works in mobile Safari, Chrome and Firefox
- No app to install
- The stamped PDF saves straight to your phone
