Benefits
Good to know about this tool
Stamps a semi-transparent, diagonal text onto every page of a PDF file without changing the original content.
So drafts, confidential documents or sample copies can be clearly marked as such.
- Mark drafts as 'DRAFT' before final approval
- Label confidential documents as 'CONFIDENTIAL'
- Mark sample invoices as 'SAMPLE'
- Short, clear text reads most clearly
- For official documents, keep an additional unwatermarked original
Frequently Asked Questions
Can I change position or color?
Currently the text is placed centered, diagonally, in gray-transparent — a fixed default for all PDFs.
Can the watermark be removed later?
No, the watermark is permanently embedded in the PDF.
