Comprehensive Guide & Mathematical Breakdown
The Watermark PDF tool stamps a text watermark diagonally across every page of a PDF document, commonly used to mark drafts, confidential documents, or copies as "Draft," "Confidential," or with a company name.
How Watermarking Works
The tool overlays your chosen watermark text onto every page of the PDF at a semi-transparent opacity and diagonal angle, then saves the result as a new PDF with the watermark permanently embedded.
Step-by-Step Instructions
- Upload Your PDF: Select the PDF file you want to watermark.
- Enter Watermark Text: Type the text you want stamped across every page, such as "Draft" or "Confidential."
- Download the Watermarked PDF: Save your PDF with the watermark applied to every page.
Frequently Asked Questions (FAQs)
Q: Is the watermark applied to every page?
A: Yes, the same watermark text is stamped across all pages of the document.
Q: Can I remove a watermark after adding it?
A: Once downloaded, the watermark is part of the page content; you would need to re-upload your original, unwatermarked file to produce a clean copy.
Q: Is my PDF uploaded to a server?
A: No. Watermarking happens entirely inside your browser.
