Your file never leaves your device

This tool runs entirely in your browser using pdf-lib. Nothing is uploaded. Safe for Aadhaar, PAN, bank statements, and confidential documents.

Will the watermark appear on every page?

Yes, the watermark is applied to all pages of the PDF automatically.

Can I remove a watermark I added?

Watermarks added with this tool are embedded as text overlays. You can use the PDF Editor to attempt removal, but it depends on the PDF structure.

Are my files uploaded?

No. The watermark is added entirely in your browser using pdf-lib. Your file never leaves your device.

What opacity should I use?

For a subtle background watermark, 20–30% works well. For a clearly visible mark, use 50–60%.
