Stamps

A stamp is a labelled mark such as APPROVED or DRAFT that you place on a page. Stamps are annotations, so you can select, move, restyle and delete them afterwards.

Place a stamp

  1. Press S or choose Tools ▸ Stamp. In the app: Help ▸ Show me
  2. In the options bar, click the stamp button (tooltip Choose a stamp) and pick a stamp from the palette. In the app: Help ▸ Show me
  3. Optionally set the colour (Green, Red, Blue or Orange), the stamp shape, the Rotation (-45 to 45 degrees) and Add date, which places a second "DATE:" stamp under the first.
  4. Click the page to place the stamp at its default size, or drag to draw it at the size you want.

Kinds of stamp

The palette has three tabs.

Tab Contents
Standard 20 ready-made stamps, such as APPROVED, APPROVED AS NOTED, REJECTED, DRAFT, FINAL, CONFIDENTIAL and VOID
Dynamic APPROVED, REVIEWED, RECEIVED, REJECTED, REVISED and COMPLETED, with a second line such as "by A. Example · 2026-10-07" filled in when you place them
Custom Your own stamps

For dynamic stamps, choose the Date format and tick Author, Date and Time as needed. The author comes from your Author name.

Create your own stamps

On the Custom tab:

  1. Choose Create stamp… to make a text stamp: enter one line of text, then choose Colour, Shape and whether it has a Border.
  2. Choose From image… to make an image stamp from a PNG or JPEG. Tick Remove light background and adjust the Threshold if the picture has a white background.
  3. Use the pencil icon to rename a custom stamp, or the cross to delete it.

Default stamp shape

Stamps are rectangles unless you choose otherwise. To change the shape for new stamps, open Edit ▸ Preferences…, go to Annotations and set Default stamp shape to Rectangle, Rounded, Circle or Ellipse. See Preferences.
