Electronic signature software – also referred to as electronic digital signature software, e-signature software, e-sign software, digital signature software or document signing software – allows you to draw, type or upload a sound or image that can serve as your legal signature in an electronic transaction. PDF.co offers this type of software online for free. Many providers’ online software also lets you encrypt a digital signature or «fingerprint» into your document when you add your electronic signature, adding security.

The basic digital signature software process

Every provider has slightly different approaches to free electronic signature software, meaning you might have vastly different interfaces or need to do more or less clicking. The general process of getting your electronic signature (and if offered, a digital signature), into your document, however, is the same:

  • Upload your file.
  • Specify who needs to sign with names and email addresses (this may be you, you and others, or just others).
  • Add signature fields.
  • Add your signature by drawing, uploading an image, typing, etc. if you are signing.
  • Send the document to your specified recipients so they can sign and send it back to you.

In most cases, free digital signature software will alert your recipients that the transaction is legally binding and ask that they click to confirm the signature.

Using an app for greater flexibility

Modern companies and clients are more mobile than ever. They need to be able to work even when a solid Internet connection isn’t available. Subsequently, many providers also offer apps you can use to sign documents from your laptop, tablet or even your smartphone. The app, which syncs with the online service, lets you perform every step in the signing process but sending the document to your recipient offline. Then, when you have a connection again, it delivers the sign request messages or alerts the sender you’ve added your signature.
