How to use Add a Stamp to a PDF
- 1. Load the PDF. Drop the document into the workspace and select which pages should get stamped, using the thumbnail grid for multi-page documents.
- 2. Pick a stamp label. Choose Draft, Approved, Confidential or Final from the Stamp list, or select Custom text and type your own wording for anything those presets do not cover.
- 3. Set color and opacity. Pick a Color that stands out against the page content, then use Opacity to control how much the underlying text shows through the stamp.
- 4. Download the stamped PDF. Generate the file and save it. The stamp is drawn diagonally across the selected pages as part of the page content.
When to use Add a Stamp to a PDF
Add a Stamp to a PDF overlays a large diagonal label like Draft or Confidential across a page, or any custom text you provide. It communicates a document's status at a glance without editing the text underneath.
- Marking a document still in review. A report circulated for feedback should not be mistaken for the final version. Stamping it Draft in a bright color makes the status obvious the moment someone opens it.
- Flagging sensitive material. A PDF containing internal financials needs a visible warning before it is shared. A Confidential stamp at reduced opacity keeps the text readable while signaling caution.
- Confirming sign-off on a design proof. A client-facing proof PDF needs an Approved stamp once sign-off happens, giving everyone downstream a clear visual marker that the file is locked.
