Why use Love2PDF for Add Watermark to PDF Free
Full customisation without complexity
Set the text, adjust the size from subtle to bold, control the opacity so content stays readable, choose the angle, and pick a colour. Everything in one panel with a live preview. For a detailed guide on customisation options, see how to add a watermark to PDF.
Applied to every page automatically
You set the watermark once and it is applied to every page in the document — whether your PDF has 2 pages or 200. Before watermarking, you may want to merge multiple documents into one using our Merge PDF tool, or split out the specific pages that need watermarking using Split PDF.
Common use cases built in
CONFIDENTIAL for legal documents. DRAFT for work in progress. Your company name for branded deliverables. Do NOT COPY for sensitive materials. Type whatever you need. After watermarking, if the file is too large to email, our Compress PDF tool will reduce the file size significantly once it launches. In the meantime you can use Rotate PDF or Reorder PDF Pages to make any remaining structural changes before distributing.
Processed in your browser
Confidential documents get watermarked without being sent anywhere. The watermark is applied locally using JavaScript and the file downloads directly from your browser.
Common uses for Add Watermark to PDF Free
Watermarks serve more purposes than just marking something confidential. Law firms stamp DRAFT on documents circulated for review before final sign-off. Designers add their studio name to client deliverables before final payment. Educators mark exam papers DO NOT COPY before distribution. Photographers watermark PDF portfolios with their name before sending to clients. Businesses add INTERNAL USE ONLY to policy documents shared outside the company. Any situation where you need to communicate the status or ownership of a document at a glance is a watermark situation.
