21 Best Electronic Signature Apps

What is an electronic signature?

An electronic signature is a replacement for a handwritten signature.

With an electronic signature app, you can sign, send and store documents like contracts, proposals, invoices, and more.

And the best part is you don’t need to travel to be physically in a destination to sign a contract. You can do it in minutes with a signature app.

If the document requires several signers, you can also set up users’ workflow to sign it in the correct order. Going paperless and saving time and money is a good step ahead.


What types of documents can be signed electronically?

All types of documents can be signed electronically, although Word and PDF are the most popular.


Are electronic signatures legally binding?

Electronic signatures are legally binding in all the states of the US, in more than 30 European countries, and many countries around the world.

You should check with local authorities the requirements and type of documents accepted. Also, check the website provider for compliance and security.

What is the difference between an electronic signature and a digital signature?

Although these terms are often used interchangeably, an electronic signature is different from a digital signature. Let’s see:

The digital signature is used to secure sensitive data and documents. It needs a digital certificate from certification authorities. When a digital signature is applied to a copy, a digital certificate is bound to your sign data and encrypts the document.

This proves the document´s authenticity and its source and makes sure the document has not been tempered.

On the other hand, the electronic signature is used to verify a document, showing intent to sign it. The electronic signature can be scanned and cannot be verified. For example, you can draw a signature in MS Word, stamp it, or type it on a document using some electronic signature app.

We have reviewed 21 electronic signature apps for you. Many of these systems provide both electronic and digital signatures capabilities.
