Keep the original: editing can invalidate digital signatures, and rebuilding pages may not preserve forms, bookmarks or document metadata.
When to use Add a Watermark to PDF
Label a review document as a draft. Choose a mark that communicates context without covering the information a reader needs.
How to use this tool
- Open a supported unencrypted PDF and choose text or an image mark.
- Set page scope, position, size, opacity and rotation.
- Apply the watermark and inspect placement on different page sizes and rotations.
Output and limits
A watermark is visible page content, not encryption, access control or identity verification. Font support can be limited, and document edits can invalidate signatures.
Frequently asked questions
Does a watermark prevent copying?
No. It communicates a visible label and does not restrict access or copying.
Why should I inspect rotated pages?
Page geometry and rotation can affect the apparent placement of a mark. Review all affected page types.
