What this tool does

Watermark PDF draws a stamp on the pages of a PDF: a word such as CONFIDENTIAL, DRAFT or COPY, your company name, or a logo image. You see it on a preview of the first page while you adjust it, and the saved file keeps everything else in the document as it was.

Features

  • Text or image: three standard font families, bold, any colour; or a PNG with a transparent background, sized as a share of the page width.
  • Nine positions or a repeating pattern that covers the whole page, which is harder to crop out.
  • Angle and opacity: diagonal, upright or sideways, from faint to solid.
  • On top of or behind the page content.
  • Chosen pages only, using ranges such as 2-5, 9.
  • Upright on every page, including landscape and rotated pages.

Limits

  • One PDF at a time, up to the memory of your device.
  • Password-protected PDFs must be unlocked first.
  • A watermark can be removed by someone with a PDF editor; it marks a document, it doesn't secure it.
  • Text in scripts other than Latin is added as an image, so it can't be searched.

Where your file is processed

This tool works in your browser: your PDF is processed on your own device, so it isn't sent to our server for this tool. Some other tools on UtiloNest do use our server, and their pages say so.

Frequently asked questions

Can someone remove the watermark?

A watermark is an extra layer drawn on each page, so a person with a PDF editor can delete it. It deters casual copying and shows the document's status; it isn't a lock. To stop people opening the file, add a password with Protect PDF as well.

Will the text in my PDF still be searchable?

Yes. The original pages aren't flattened or turned into images. Your watermark is added on top of them (or behind them, if you choose), and everything else stays selectable.

Can I write the watermark in Urdu, Hindi or another script?

Yes. Latin-script text is written with a standard PDF font, so it stays sharp at any zoom. For other scripts, the text is drawn with your device's own fonts and added as a high-resolution image, so it shows correctly in every PDF reader.

Why can't I see a watermark that I put behind the content?

The "behind the page content" option places the stamp under everything already on the page. Scanned pages are usually one full-page picture, which covers it completely. Use the normal layer with a low opacity for scans.

Does it work on pages that are turned sideways?

Yes. Each page's rotation is taken into account, so the watermark shows upright and in the chosen spot on landscape and rotated pages too.
