FAQ

Common questions

Yes, the utility supports both text strings such as ‘CONFIDENTIAL’ or ‘DRAFT’ and uploaded graphic logos in PNG, SVG, or JPEG formats. When using a logo, transparent PNG images work best to ensure underlying document content remains legible beneath the graphic. You can switch between text and image modes seamlessly within the configuration panel.
The watermark applies uniformly across all pages of your uploaded document by default, but you can also choose specific page ranges if you wish to exclude cover pages or appendices. The positioning and styling parameters you select are accurately rendered on every targeted page.
The tool embeds watermarks into the PDF page stream as flattened graphical layers, making simple removal difficult for casual readers. While advanced PDF editing software can modify unprotected vector elements, applying a transparent, diagonal watermark across the entire page body provides strong visual deterrence against unauthorized distribution and reproduction.
All file reading, text rendering, and PDF restructuring are executed client-side through local browser capabilities. Your uploaded files are never transferred across the network or stored in external databases. Closing the window permanently removes the document from active memory.

About the Watermark PDF

The Watermark PDF utility allows businesses, legal teams, and independent creators to safeguard sensitive documentation before distribution. It provides precise control over opacity, typography, and positioning so users can mark drafts, assert copyright, and brand materials without altering original page formatting. The browser-based interface makes rapid document protection accessible on any workstation.

Benefits

  • Deter unauthorized redistribution — overlay prominent confidential or draft notices across sensitive business records.
  • Brand corporate documents — apply company logos or copyright notices uniformly to training manuals, eBooks, and whitepapers.
  • Fine-tune stamp visibility — calibrate opacity, rotation angles, and font dimensions so watermarks protect without obscuring text.
  • Target specific pages — stamp the entire document or restrict watermarking to internal content while preserving cover page presentation.

Privacy

The watermarking process runs entirely in your local browser session, meaning your documents remain confidential and are never uploaded to our servers.
