Watermark PDF — FAQ

Does a watermark secure my document?
It discourages casual copying but does not restrict access. For real protection, use encryption and permissions in your PDF editor.
What opacity should I use?
10–20% for a status mark such as DRAFT or CONFIDENTIAL; higher if the mark should be hard to ignore.
Can I add the watermark to only some pages?
This tool stamps every page. To mark a subset, split the document, watermark the part, then merge back with Merge PDF.
