When this tool is useful
Watermarks are helpful visual cues but should not be treated as security controls. Someone with PDF editing software may still remove them. To protect confidential files, use an appropriate document access-control workflow rather than relying on a diagonal label alone.
Frequently asked questions
Is this secure DRM?
No. The watermark is a visible label, not copy protection.
Can I choose opacity and position?
This starter uses a preset diagonal style; advanced controls can be added later.
Processing depends on your device and browser memory. Very large documents may take longer or fail.
Helpful tips and related tools
A DRAFT or CONFIDENTIAL watermark makes a review copy easier to identify. This adds visible text to the PDF but it does not protect the document against copying or editing; do not treat a watermark as access control.
Make a PDF visibly identifiable
A diagonal label such as DRAFT, REVIEW COPY or SAMPLE can reduce confusion when multiple versions of a document circulate. Use a short phrase that remains readable without covering key figures, signatures or legal clauses.
The watermark is a visual indication, not a security barrier. It does not prevent copying, editing or distribution, and it is not a substitute for encryption or permissions. Review every page after exporting, especially where the document contains diagrams or dark backgrounds.
