How to Insert Signatures in Google Docs

Google Docs is an excellent tool for creating professional collaborative documents with your remote team and sharing them with clients and customers. Unfortunately, its native digital signing abilities are limited.

If your business needs to be able to sign documents electronically, then you need a professional and convenient method. That’s where digital signature add-ons for Google Docs come in handy and, in most cases, are easy to use. 

The safest and most convenient way to add signatures to Google Docs is by using one of the many professional add-ons available. There are two ways to get these add-ons. The easiest is from the Google Marketplace. Alternatively, you can get them directly from the add-on developers’ websites.

Here are some notable Digital Signature Add-ons for Google Docs:

  1. AirSlate
  2. DocuSign
  3. Signable
  4. signNow
  5. PandaDoc
  6. HelloSign

1. airSlate


AirSlate allows you to sign documents from anywhere, without having to worry about printing them out and signing them by hand.

All you need to do is run the Signature Wizard and type (yes, type) your name into the wizard. Your signature will appear in a cursive font like you'd signed it by hand. If you prefer something more personalized you can also upload your personal signature. Even that can be done by snapping a photo of your signature and then uploading it via airSlate.

What is a Digital Signature?

A digital signature is a way to verify that an authorized person issues a document. It’s similar to signing a piece of paper in person, except this is in the digital world. The essential thing to understand about digital signatures is that it isn’t as simple as appending an image to a document.

For example, you cannot simply drop a scanned image of your signature into a document and consider it “digitally signed.”

How Digital Signatures Work

Digital signatures ensure that no unauthorized changes to documents are possible once the signature is in place. The process works by creating a unique hash of the document and encrypting it using the sender's private key. 

Each generated hash is unique and will change if there are any amendments to the original document. Once the system completes the hashing process, the document is “digitally signed.” You can then send it to a recipient.

When the recipient gets the document, their system will generate another hash of the digital copy. This hash uses the sender's public key to decrypt the sender's hash that came along with the document. Matching hashes serve as proof that the document is original and unmodified.

Why You Should Digitally Sign Your Google Docs?

If you’re a business owner, there are many reasons why you should sign your documents digitally. First, however, there’s a myth that needs to be dispelled. Just because something is convenient doesn’t mean it’s less secure than good old pen and paper.

Here are some of the top reasons why you should switch to digital signatures;

It’s Faster and More Convenient

The most apparent reason is efficiency. You can get things done faster and more efficiently by signing documents electronically, rather than having to print them out and fax them back or mail them in. You can also sign and deliver documents from anywhere, even between countries.

Digital Signatures Are Safer

When you sign documents electronically, you know that there will be no mistakes made when it comes time for filing with a court or other entity. You also won’t have to worry about anyone altering the document without your permission.

It also reduces the risk of losing documents or having them get lost in transit because there's no physical paper copy involved; your signature is stored on the cloud instead.

They Establish Trust

The digital space today also supports commercial activities, and digital signatures can be a way of building trust between parties involved in transactions. For example, the buying and selling of goods, signing contracts or sharing confidential information.

Digital Signatures are Widely Accepted

A digital signature has the same legal value as a handwritten signature. Companies and individuals must adhere to specific rules when signing documents digitally. Because of these governing regulations, digital signatures are often legally binding.

Improves the Customer Experience

Instead of having customers wait for contracts or proposals as they get sent via snail mail, digitally signed versions will arrive much faster. Imagine having a business discussion one day and having a signed contract settled within moments of that conversation. It streamlines the customer experience in so many ways.


While Google Docs doesn’t have a dedicated digital signature feature yet, there are plenty of alternatives. All of the solutions I’ve outlined work well with Google Docs and each has its own set of features to make signing docs easier. 

For example, if you need someone to sign a document on their mobile device at any time, PandaDoc and HelloSign would be your best choices. The bottom line is that no matter which solution above works best for your needs, you can easily integrate it into Google Docs.
