Watermark PDF
Stamp a text or image watermark onto a PDF.
FAQ
- Is my PDF uploaded to a server?
- No. All processing happens entirely in your browser using pdf-lib. Your file never leaves your device.
- What does the watermark look like?
- The watermark text is drawn diagonally at roughly 45 degrees, centered on each page, in large semi-transparent letters (opacity ~0.2) so the underlying content remains readable.
- Will the watermark appear on every page?
- Yes. The watermark is stamped onto every page of the PDF, regardless of page count or orientation.
