Add Watermark to PDF

Stamp a text or image watermark across every PDF page with control over opacity, rotation, size and position. Protect drafts and confidential files.

Add Watermark to PDF stamps a text or image watermark across every page of a PDF, with full control over opacity, rotation, size and position, and the whole process runs client-side in your browser. Type a word like DRAFT or CONFIDENTIAL, or upload a company logo, then preview how it sits over the existing content before applying it to the whole document.

It is the tool to use before circulating a draft, sharing a confidential report, or distributing a document that needs a visible ownership mark. You can target specific page ranges so cover pages or signature pages stay clean, and adjust the watermark's transparency so the underlying text remains fully legible underneath.

How to use the Add Watermark to PDF

  1. Upload the PDF you want to watermark using the file selector or drag-and-drop.
  2. Choose text or image mode, then type your watermark text or upload a logo file.
  3. Set the opacity, rotation angle and size so the watermark sits clearly but doesn't obscure the content.
  4. Position the watermark using the alignment controls, such as centred or tiled across the page.
  5. Enter a page range if only some pages should be watermarked, leaving others untouched.
  6. Apply the watermark and download the stamped PDF.

Why use this tool

Text or logo watermarking

Switch between a typed text stamp like DRAFT or CONFIDENTIAL and an uploaded image watermark such as a company logo, covering both branding and document-control use cases with one tool.

Fine opacity and rotation control

Adjustable opacity keeps the underlying text readable while the mark stays visible, and rotation lets you angle the stamp diagonally across the page the way traditional paper watermarks appear.

Selective page ranges

Specifying which pages receive the watermark means covers, appendices or signature pages can be left clean while the main body carries the stamp, without exporting two separate documents.

Common use cases

Choosing an opacity level

Around 15–30% opacity keeps the mark clearly visible without interfering with reading the underlying text — the setting most business documents use. Push it higher, closer to 50%, only when the goal is specifically to discourage screenshots or unauthorised reuse of the page.

Text vs image watermarks

Text watermarks are quick to set up and instantly communicate status words like DRAFT or CONFIDENTIAL. Image watermarks work better for branding, letting you stamp a logo consistently across every page of a proposal, report or portfolio without retyping text each time.

Applying to specific pages only

Enter a page range such as 2-10 to skip the cover and final signature page, which is common practice for legal and business documents where the first and last pages need to stay visually clean while the body pages are marked.
