About This Tool
Add Watermark is a crucial security and branding tool for PDF documents. By overlaying a custom stamp, you can clearly mark files as "DRAFT," "CONFIDENTIAL," or "INTERNAL ONLY," deterring unauthorized sharing and ensuring document status is always clear.
Our tool supports both text-based stamps and image-based watermarks (such as company logos). You have full control over the visual presentation—adjust transparency levels so the background text remains readable, rotate the watermark for a diagonal look, and choose which pages to protect.
100% Browser-Based Security: Your watermarking process is entirely local. Because your files are never uploaded to our servers, your intellectual property and company logos remain strictly confidential throughout the entire process.

Frequently Asked Questions
Is the watermark permanent?
Once you apply the watermark and download the file, it becomes part of the PDF layers. While sophisticated PDF editors can sometimes remove layers, it serves as a strong visual deterrent and branding tool.
Can I watermark only the first page?
Yes, you can choose to apply the watermark to all pages, only the first page, or a specific range of pages depending on your specific needs.
What image formats can I use for watermarking?
We support standard image formats including PNG (recommended for transparency), JPG, and SVG for sharp, scalable logos.
