DRAFT

How Watermark PDF works

  1. Upload an unprotected PDF.
  2. Enter text (or pick DRAFT / CONFIDENTIAL / SAMPLE).
  3. Adjust position, size, opacity, rotation, or tile the mark.
  4. Check the mock preview, then download a branded PDF.

Limits

  • Text only (Latin / WinAnsi). Image and logo watermarks are not supported here.
  • The mark is drawn on top of existing content, not underneath it.
  • Helvetica Bold only — this is not a Chrome print watermark.
  • Tiling is a simple 3×4 grid. The preview is a sample sheet, not your first PDF page.
