Add a Watermark to a PDF: what you need to know
When sharing a draft, sample, or work document, a watermark helps visually identify its status or origin. Prisma Space allows you to write text and apply it to the pages of a PDF copy.
The watermark is represented diagonally and with transparency, so the document content remains legible. You can use a name, an indication like DRAFT, or a reference from your organization. The result is a new downloadable PDF.
How to use this tool
- Select the PDF file you want to add the watermark to.
- Enter the text that will appear as the watermark.
- Run the process and review the resulting PDF before sharing it.
Common questions
Does the watermark appear on all pages?
The tool applies the text to the pages of the processed document.
Does the PDF watermark protect the document with a password?
No. It adds a visual identification, but does not replace encryption or password protection.
