Fill & Sign

Signatures, stamps and form marks, in the viewer and from code.

In the viewer

  • The Signature tool opens the signature list: saved signatures (kept in the browser) and New Signature, with Draw, Type and Upload, in black, blue or red ink.
  • The Stamp tool opens the stamps panel with previews of every stamp, and Create New Stamp for your own text, font, colours and an author / date line.
  • The Fill and Sign tab places text, check marks, crosses, dots and today’s date (with a calendar to pick another day).
