Watermark PDF

Stamp diagonal text across every page of a PDF, for example to mark a copy of your documents as for a single use.

How to use

  1. Click the upload box and choose a PDF.
  2. Type the watermark text (up to 40 characters).
  3. Click “Add watermark & download”.

What to expect

  • Each file can be up to 15 MB.
  • The text is drawn diagonally across the middle of every page in semi-transparent grey. Its position, colour and size are fixed.
  • The result is rebuilt from page images, so text inside the original PDF will not be selectable or searchable.
  • This tool loads the open-source pdf.js reader from a public CDN the first time it is used; that fetches the reader code, not your file.

Common questions

Can I change the colour, size or position of the watermark?

No. The text is always grey, semi-transparent and diagonal across the centre of each page.

Can the watermark be removed afterwards?

It is drawn into the page images, so it cannot be switched off like a layer. Keep your original file if you may need a clean copy.

Is my PDF uploaded anywhere?

No. Your file is processed by your browser; only the pdf.js reader code is downloaded.
