How to Sign a PDF

  1. Choose your PDF. The pages appear in the editor.
  2. Create your signature: Draw, Type or Upload, choose the ink colour, and click Place signature.

  4. Undo anything you do not like, then click Save PDF.

Is an Electronic Signature Valid?

A picture of your signature on a PDF is a simple electronic signature. It is accepted for many everyday documents – rental agreements, forms, consent letters and invoices. Some contracts and government processes require a certified digital signature (with a certificate from an authorised provider); check what the recipient needs.

Tip: a photo of your signature on white paper, taken in good light, gives the most natural result with Upload.
