What watermark text can I use?

You can type any custom text. Common watermarks include DRAFT, CONFIDENTIAL, SAMPLE, DO NOT DISTRIBUTE, APPROVED, and FINAL. The tool supports any text up to 50 characters.

How does the opacity slider work?

The opacity slider controls how transparent the watermark appears. At low opacity (10-20%), the watermark is subtle and does not obscure the document content. At high opacity (80-100%), the watermark is prominent and unmistakable.

Can I choose diagonal or horizontal orientation?

Yes. You can set the watermark to horizontal (straight across) or diagonal (tilted 45 degrees) orientation. Diagonal is the most common for watermarks because it is visible across the full page width.

Will the watermark cover the document content?

The watermark overlays on top of the document content. At low opacity, the document content remains readable through the watermark. You can adjust the opacity and position to find the right balance.

Is my PDF data sent to a server?

No. All processing happens locally in your browser using JavaScript. Your PDF file is never uploaded to any server, ensuring complete privacy for confidential documents.
