Add Stamps

Place image stamps on your PDF pages using an embedded viewer with a stamp annotation toolbar. Stamps can include your name for attribution, making this useful for approval workflows, review processes, and document marking.

How It Works

  1. Enter your name in the Stamp Username field. This name will appear on stamps you create.
  2. Upload your PDF file by clicking or dragging it into the drop zone.
  3. The stamp editor opens with your document loaded in a viewer.
  4. Use the toolbar's image stamp tool to select and place stamps on any page.
  5. Position and resize stamps as needed.
  6. Click Save Stamped PDF to download the result.
