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).
