Add a watermark to a PDF

Stamp CONFIDENTIAL, DRAFT, your own words or a logo on all or chosen pages. Your file stays on your device.

Drop a PDF, or click to choose

You will see the watermark on your pages as you set it up.

Need to write on the pages too? The PDF editor adds text, signatures and highlights.

How to add a watermark to a PDF

  1. Open your PDF. Drop the PDF on the page or click to choose it. The first page appears with a sample watermark straight away.
  2. Set up the watermark. Tap a word such as CONFIDENTIAL or DRAFT, or type your own, or choose a logo. Pick diagonal, centre, a corner or tiled, then set the size, opacity, rotation and colour.
  3. Choose the pages. Keep all pages, pick odd or even pages, type a range, or click pages on the grid.
  4. Download. The preview is the real result. Download saves the watermarked PDF.

Text or a logo, wherever you need it

Text that stays text

Latin text is written into the PDF as real text in a standard font, so it can be selected and searched. Text in other scripts, such as Chinese or Arabic, is added as a sharp picture of the words, drawn with your device’s fonts.

A logo with transparency

A PNG keeps its transparent background; a JPG works too. The image is stored once in the file and reused on every page, so the PDF stays small.

Diagonal, corner or tiled

Diagonal runs corner to corner at the angle of each page. Corner places it at any of nine points. Tiled repeats it across the page with the spacing you choose.

Right on every page

The mark is placed as each page is shown, so it sits the same way up on portrait, landscape, turned and odd-sized pages.

Your file stays on your device

The watermark is added in your browser. Nothing is uploaded, so it suits contracts, statements and drafts you would rather not send anywhere. The rest of the PDF is left as it is: fillable form fields keep working, links still jump, and bookmarks stay.

Watermarking a photo instead? Use watermark an image. To add a signature or a note as well, open the result in the PDF editor, and to lock the file afterwards use Protect PDF.

Common questions

How do I add a watermark to a PDF?
Open the PDF here, tap a word like CONFIDENTIAL or type your own, choose where it goes and how strong it looks, then download. The preview shows the real result.
Can I watermark only some pages?
Yes. Choose odd or even pages, type a range such as 1-3, 7, or click the pages you want on the page grid.
Can I use my logo as the watermark?
Yes. Choose Logo and pick a PNG or JPG. A PNG with a transparent background keeps it.
How do I make the watermark lighter?
Lower the opacity. 20 to 30% is typical for a watermark that stays readable over the text.
Can the watermark go behind the text?
Yes. Choose Behind content and it sits under the page's text. On a scanned page it is hidden, because the whole scan is one picture covering it; keep it over the content for scans.
Can someone remove the watermark?
A watermark added this way can be removed by someone with a PDF editor, as with any added mark. It shows who a copy is for or that it is a draft; it is not a lock. To stop editing, also protect the PDF with a password.
Will my form fields and links still work?
Yes. The watermark is drawn onto the pages without rebuilding the file, so fields stay fillable, links still work and bookmarks stay.
Is my PDF uploaded?
No. The watermark is added in your browser and the file never leaves your device.
Can I open a password-protected PDF?
Yes, if you know its password. It is checked on your device, and the file you download has no password.
Is it free?
Yes. There is no sign-up, and the only watermark on your file is the one you add.
