How it works

  1. 1. Select a PDFChoose the PDF you want to watermark. It opens in your browser and is never uploaded.
  2. 2. Choose text or a logoType your watermark text, or upload a PNG or JPG logo.
  3. 3. Adjust the lookSet the size, angle, colour, transparency and position. The preview updates as you go.
  4. 4. DownloadPick all pages or specific pages, then click Watermark & Download. The new PDF is created on your device.

The watermark is added as a visible layer on each page. It discourages copying but is not tamper-proof — someone with a PDF editor could remove it. Text watermarks support standard Latin letters, numbers and common symbols; for other scripts, use a logo image instead. Password-protected PDFs need the password removed first.

Frequently asked questions

Is my PDF uploaded anywhere?
No. The PDF and your logo stay in your browser. Nothing is sent to a server.
Can I watermark only some pages?
Yes. Choose "Specific pages" and enter page numbers or ranges, for example 1, 3, 5-7.
Can I use my company logo?
Yes. Switch to Image and upload a PNG or JPG. A PNG with a transparent background looks best.
Can the watermark be removed?
It is added on top of the page content, so it is visible to everyone, but a determined person with editing software may be able to remove it. It is a deterrent, not a security lock — use Protect PDF if you need a password.
Why does my text show an error?
Text watermarks use a built-in PDF font that covers standard Latin characters. Letters from scripts such as Urdu, Arabic or Chinese are not supported in text mode — create an image of the text and use Image mode instead.
Does it work on my phone?
Yes. The tool works in modern mobile browsers. Very large PDFs may be slow on phones with limited memory.
