How to Add a Watermark to a PDF

Overlaying text like "CONFIDENTIAL" or "DRAFT" across every page — how it works, and when a watermark is (and isn't) enough protection.

How to Add a Watermark to a PDF

Watermark PDF stamps CONFIDENTIAL, DRAFT, or a logo across pages with live preview — opacity, rotation, tiling, and above/behind layering included.

Watermark PDF runs locally in your browser on TechDriven Tools. Inputs stay on your device — nothing is uploaded for this step.

When Watermark PDF is the right tool

Mark drafts before review

Stamp DRAFT or CONFIDENTIAL with a preset so reviewers never confuse a working copy with a final.

Brand client PDFs

Switch to Image/Logo mode and tile a light logo so every page carries ownership.

Void mistaken invoices

Use VOID preset at stronger opacity so a wrong PDF cannot be reused quietly.

How to run Watermark PDF on TechDriven Tools

  1. Open Watermark PDF.
  2. Set the options that matter — Configure: presets (CONFIDENTIAL/DRAFT/…), Text vs Image/Logo, opacity, rotation, tiled mode, Behind content, position grid, {date}/{page} placeholders.
  3. Run and verify the output — Download or copy the result, then spot-check before you replace originals or share externally.

Read every label before running. For Watermark PDF, the controls that change outcomes most are: presets (CONFIDENTIAL/DRAFT/…), Text vs Image/Logo, opacity, rotation, tiled mode, Behind content, position grid, {date}/{page} placeholders. Change one control at a time when you are comparing results.

Privacy on this workflow

Mistakes that waste time with Watermark PDF

Watermark PDF accelerates the workflow; it does not replace your judgment or professional advice where required.
