Signing online documents can be time-consuming. You may have to open your digital document, change its format, print it, sign it, scan it back into your computer, and reformat it again all before sending it to the recipient.

This is where electronic signature apps — or eSignature apps — come to the rescue. They allow you to sign and send documents in a matter of seconds.

In this blog post, we'll cover the information you need to understand the benefits of signature apps as well as 20 of the best eSignature tools.

eSignature software makes it easy to collect and store these kinds of signatures, usually by enabling you to put entry forms in your documents. They also add an extra level of security by ensuring signatures can be verified.

Are electronic signatures legally binding?

In a word, yes.

There are many cases in which judges have ruled in favor of the veracity of eSignatures. Whenever there's consent and intent, which is almost always the case, eSignatures are legally binding.

What is a digital signature?

But what about digital signatures? Are the terms interchangeable?

A digital signature is not the same as an electronic signature. It's an encrypted "packet" associated with a document.

Digital signature software creates a condensed version of a document — called a hash — which will be encrypted using a key in a signatory certificate. This encrypted "hash" is the signature. To validate the signature, the hash is decrypted with the signatory's key and compared to the original document.

Many of the signature apps we'll cover below offer features for both electronic and digital signatures, so you don't have to pick between the two.
