PicoPDF creates an image of your signature, then inserts it into the document like any other image. The signature image is created with the Add Signature dialog, where you can draw, type, or select an image file to represent your signature. Quick signatures give you full control over your signature appearance, but are not considered secure and can be forged.

To add a Quick Signature to a document, use the Sign Toolbar or Sign Menu. For more information, check the Signing Documents help page.
