Mark a document as a draft, protect a design you are sharing with a client, or brand a price list with your logo. Type any text (Hindi, Punjabi and emoji work too) or upload a logo, choose diagonal, centred, repeated or a small corner mark, and set how see-through it is. Everything runs on your device.
loading toolHow to add a watermark to a PDF
- Choose your PDF.
- Type the watermark text or choose your logo, then pick the layout, size and strength.
- Press Add watermark and download the marked PDF.
Good to know
- Around 20–30% strength keeps the page readable while the mark is still obvious.
- A PNG logo with a see-through background looks best.
Questions
Can someone remove the watermark?
A determined person with PDF editing software can remove or cover any watermark. A repeated (tiled) watermark is much harder to crop out than a single one, so use it for sensitive previews.
Can I watermark only some pages?
Yes. Type pages such as 1-3, 7 in the Pages box. Leave it empty to mark every page.
Will my text stay sharp?
English and other Latin-alphabet text is added as real PDF text, sharp at any zoom. Other scripts and emoji are added as a high-resolution picture so they always display correctly.
My PDF says it is password-protected. What now?
If you know the password, open it with our Remove PDF Password tool first, then come back. We cannot (and will not) break passwords you do not have.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
