Watermark a PDF in your browser

Watermark a PDF for free without uploading it. Text is drawn on every page in your browser, so the original stays selectable and the file never leaves this device.

Three steps to watermark a PDF: open the file, set the text, download
  1. 1

    Open the PDF

    Drop a PDF onto the editor. The file stays in memory in this browser tab and is never uploaded.

  2. 2

    Set the watermark text

    Choose CONFIDENTIAL, DRAFT, SAMPLE, or type a custom phrase. Adjust opacity, rotation, position, and optional tiling.

  3. 3

    Download

    The watermarked PDF is generated in the browser and saved to your downloads folder. Every page is marked.

Open a confidential watermark, a draft watermark, or a sample watermark, or read how to add a watermark to a PDF.

How to watermark a PDF

Open a PDF in the editor above, set the watermark text, then download. The mark is real PDF text on each page, not a flattened picture of page 1. Use CONFIDENTIAL, DRAFT, SAMPLE, DO NOT COPY, or any custom phrase. You control position, opacity, rotation, color, and optional tiling. There is no file-size cap beyond what your browser can hold in memory.

  • Applies the same watermark to every page, not a copy of page 1
  • Keeps selectable text and existing links
  • Works offline after the page has loaded

Watermark a PDF without uploading it

Most online PDF sites upload your document to a server, process it, then let you download the result. That is a problem for contracts, payroll, medical records, and unpublished manuscripts. This tool never posts the file. The PDF is read locally, watermarked locally, and saved locally. It runs in Chrome, Edge, Firefox, and Safari on Windows, Mac, and Linux. Adobe Acrobat is not required.

CONFIDENTIAL, DRAFT, and SAMPLE marks

A confidential watermark tells recipients how to handle the file. A draft watermark tells them not to treat it as final. SAMPLE and DO NOT COPY are visual deterrents on review copies. Open the confidential, draft, or sample tools for those defaults, or see the how-to guide for Acrobat, Mac Preview, and Word comparisons. Use tiling when you need the mark to survive a crop or a screenshot of a single paragraph.

Tips

  • Keep opacity between 15% and 35% so the text underneath stays readable.
  • Rotate to about 45° or 330° so the mark is harder to crop out.
  • Use Helvetica-style sans type: it stays clear at low opacity.

Frequently asked questions

Is it free to watermark a PDF?

Yes. There is no account, no page limit, and no watermark of our own added to your file.

Does watermarking a PDF work on Mac and Windows?

Yes. The tool runs in the browser on Windows, Mac, Linux, iPhone, and Android. Nothing to install.

Do I need Adobe Acrobat to watermark a PDF?

No. Chrome, Edge, Firefox, and Safari are enough. Acrobat Pro is not required.

Does the watermark apply to every page?

Yes. Each page is watermarked independently with vector text. A ten-page PDF still has ten distinct pages after download.

Do you store my PDF?

No. The file never leaves your device. We do not have a processing server for documents.

Open a PDF above, set the text, and download. For step-by-step comparisons with Acrobat, Preview, and Word, see the how-to guides.
