Add Watermark to PDF
Stamp a text watermark on every page of your PDF. Customize opacity, size and position.
About Add Watermark to PDF
A watermark tells everyone what a document is — DRAFT, CONFIDENTIAL, PAID — or who it belongs to. Adding one before sharing discourages reuse of proposals, designs, and pre-release documents, and makes versions instantly distinguishable.
This tool stamps your chosen text diagonally across every page with adjustable size, color, and transparency. Because the watermark is drawn into the page content itself, it stays visible in every PDF viewer and survives printing.
How to use Add Watermark to PDF
- 1
Open the PDF
Load the document you want to protect or label.
- 2
Type the watermark text
Common choices: DRAFT, CONFIDENTIAL, your company name, or a client name for tracked copies.
- 3
Style it
Adjust size, color, and opacity. Lower opacity keeps the underlying text easy to read.
- 4
Apply and download
The watermark is drawn onto every page and the marked copy downloads. Your original stays clean.
Tips for better results
- ✓Keep opacity around 15–30% so the watermark is visible without hurting readability.
- ✓Watermark per-recipient (e.g. the client's name) to trace leaked copies of sensitive documents.
- ✓Watermark a copy, not your master file — you can't cleanly remove a baked-in watermark later.
