Are you looking for the best e-signature software to digitally sign your documents? As the world adapts to a remote and digitized workflow, companies are ditching traditional paperwork in favor of more innovative ways to review and sign documents. 

E-signature software enables you to sign documents digitally by drawing or typing in your signature, eliminating the need to take a print out and sign manually. 

In case you were wondering, digital signatures are legally binding. In fact, they work just like a physical signature. However, because online paper trails can be difficult to trace, it can prove a challenge to hold anyone accountable. 

While you can technically use any document editing software to upload and paste an image of your digital signature taken from your webcam, e-signature applications also use cryptography to record important information like your email address, as well as when, where, and how the document was signed. This creates a digital fingerprint in the event of a court case, and makes tracking things a whole lot easier.

In this article, we take a look at some of the best e-signature applications that allow you to digitally sign both protected and unprotected documents, be they in .pdf or .docx format. These apps can be used directly by company administrators while sending out paperwork, or by individual contractors and employees to reliably sign their documents.

Which e-signature software is best?

A number of e-signature applications have gained popularity over the years. The most widely known examples - and our top two choices here - are Adobe Sign and DocuSign, both of which cater to business owners looking to streamline their paperwork. 

However, because these applications are dedicated to companies, they can prove a bit too expensive for individual use. HelloSign, owned by Dropbox, is another great e-signature app for both individuals and businesses. It integrates very well with cloud storage providers like Google Drive, Box, Evernote, Microsoft OneDrive, and of course, Dropbox. 

For individual users who prefer to pay only for the exact number of documents signed, is a good choice. Finally, Docsketch is a free alternative that allows you to sign up to three documents per month for zero cost. If you’re an individual who needs to sign a document quickly and without fuss, this is an excellent option.
