In short
EnDocs AI adds a text watermark such as CONFIDENTIAL or DRAFT to all or selected pages of a PDF, with the color, size, opacity and angle you choose. The page content underneath is left unchanged.
What it is
What is Watermark PDF?
A watermark is text laid over each page to show a document's status or ownership. It tells readers a file is a draft, internal, or belongs to a specific company, and it discourages casual reuse.
You describe the watermark in words: the text, how strong it should look, and which pages. Standard diagonal placement is used by default.
Try saying
“Add a semi-transparent red DRAFT watermark across every page.”

Behind the scenes
How your file is processed
Placed and sized for each page
The watermark is positioned and scaled per page, so it fits portrait and landscape pages alike, on top of the existing content.
Colour, opacity, rotation and tiling
Choose a color by name or hex code, how transparent it is, the angle, and whether it repeats across the page.
Checked after it is applied
The result is validated, and documents that carry digital signatures or encryption are handled with safety checks so they are not silently broken.

Tips for better results
- Keep opacity low (around 20-30%) so the page stays readable.
- For several versions of one file, say so: "make an internal copy without a watermark and an external one marked CONFIDENTIAL".
- Protect the file after watermarking if you also want to control who opens it.
