    Why watermark a PDF?

    A watermark tells everyone who sees a page what it is and who it belongs to: "DRAFT" on a version that isn't final, "CONFIDENTIAL" on internal papers, "COPY" on a document you send as proof, or your logo on a portfolio or a quote. It discourages reuse because it's part of every page it's on.

    Text or picture

    • Text: type the words, then choose the size, colour, angle and transparency. 30–40% opacity is readable without hiding the content underneath.
    • Picture: pick a JPG, PNG or WEBP file. A PNG logo with a transparent background looks best.

    Where to put it

    Choose one of nine positions (corners, edges, centre), or Repeat across the page to tile it, which is much harder to crop out. Type page numbers in Pages (for example 1-3, 5) to mark only some pages; leave it empty for all of them.

    A tip for ID documents

    When you send a copy of your passport or ID card, add a watermark such as "Copy for [company], [date]". If the copy leaks, it can't easily be reused elsewhere. Scan the card first with Scan to PDF, then watermark it here.

    A watermark can't simply be switched off later, so keep your original file. To stop people editing or printing the PDF too, add a password with Protect PDF.

    Watermark: questions and answers

    Can I watermark only some pages?

    Yes. Type the pages in Pages, for example 1-3, 5. Leave it empty for every page.

    Can I use my logo?

    Yes. Choose Image and pick a JPG, PNG or WEBP file. PNG files with a transparent background look best.

    Can the watermark be removed later?

    It's part of each page, so it can't simply be switched off. Keep your original file if you need a clean copy.

    Can someone remove the watermark?

    It's drawn into the page, not a separate layer you can switch off. A determined person with editing software could cover it, which is why tiling it across the page helps.

    Is the file uploaded?

    No. The watermark is added in your browser and the PDF never leaves your device.
