What are Digital Signatures? Digital signatures offer a more secure way to sign documents. By signing a document with a Digital ID, anyone with Adobe Acrobat can verify the signer's identity and see if the document was edited after it was signed. Unlike Quick Signatures, it is impossible to forge a digital signature. Digital Signatures are only valid for files saved as a PDF. PDFs exported to other formats will not contain a digital signature. How to digitally sign a document To digitally sign a document, use the Tools > Sign menu to select one of the following menu options: - Certify with Invisible Digital Signature
- Certify with Visible Digital Signature
Or select the same options from the Sign dropdown on the Home Tab This will open the Digital ID wizard, where you will be prompted to select an existing Digital ID file (.p12 or .pfx), or create a new Digital ID. Once you've created or selected a Digital ID file to sign with, click on the blue Sign button to close the Digital ID wizard and mark the document as signed. Note that Digital Signatures are not applied until the document is saved.
