Frequently Asked Questions
Is my document secure when adding watermarks?
Absolutely. BrowserKits processes everything locally in your browser. Your PDF is never uploaded to any server, making this the safest option for watermarking confidential documents, contracts, and proprietary materials.
What watermark positions are available?
You can place watermarks in any corner, centered, or use "tile" mode to repeat the watermark across the entire page. Combine with rotation for diagonal watermarks commonly used for "DRAFT" or "CONFIDENTIAL" stamps.
Can I watermark all pages at once?
Yes! The watermark is automatically applied to every page in your PDF. This ensures consistent branding or security marking throughout your entire document with a single click.
