How to Add a Signature in Word: Complete 2025 Guide

If you use Microsoft Word to create business documents, such as contracts or proposals, you will need to insert signatures for formality or security. If you aren’t aware that Word supports native features for signature insertion, or feel frustrated or stressed because you can't figure out how to add a signature, this guide is for you.

Adding signatures to Word documents requires manual intervention, which is impractical for businesses handling large volumes of documents that must comply with global electronic signature regulations.

In this guide, we will explore options for inserting signatures in Word documents, explain the differences between electronic and digital signatures, and demonstrate how Docupilot, a full-featured document automation platform, can help you create, sign, and deliver business documents at scale.

Why Would You Need to Insert a Signature in Word?  

Contracts, proposals, and service agreements are just a few of the business documents created using Word. There are several reasons why you may need to insert a signature in these documents.

1. Creating and maintaining a professional image

Adding a signature to a Word document helps create and maintain a professional image, adds a personal touch, builds credibility with clients, colleagues, and decision-makers, and reinforces your brand.

2. Accelerating approval processes by adding electronic signatures instead of printing/signing/scanning, and resending

The old-school method of approving a document by printing it, signing it by hand, then scanning and sending it is time-consuming, cumbersome, and wastes paper.

Adding electronic signatures to Word documents speeds up the approval process, prevents paper wastage, helps you close deals faster, and has a definite positive impact on the bottom line.

3. Legal and compliance requirements for relevant documents

Industries like legal, banking and financial services, and healthcare require signed documents for regulatory and legal compliance.

Creating Your Electronic Signature in Microsoft Word  

You can either use Word's Draw tool or sign a piece of paper, scan it, and save it to a common file format like JPEG or PNG.

How to sign a Word document using the Draw tool

Word's Draw tool is a feature that you can use to draw freehand or insert shapes – such as a signature, and lines directly onto a document.

For Office 2019 and Microsoft 365, the Draw tool is turned on automatically if you are using a touch-enabled device. If it is not turned on, go to File > Options > Customize Ribbon, and check the box next to "Draw" under the "Customize the Ribbon" section.

Follow these steps to add a signature:

1. Navigate to the Draw tab
2. Select the desired pen or pencil tool
3. On a touch-enabled device, you can easily use a stylus to draw your signature. If your device is not touch-enabled, you can use a trackpad or mouse to draw the signature directly onto the document

Note that you can adjust the pen's thickness and color before drawing.

How to scan a handwritten signature into an image file

Another option for adding a signature in Word is to insert a picture of your scanned handwritten signature.

To use this option:

1. Write your signature on a piece of paper
2. Scan the handwritten signature or take a photo with your smartphone
3. Save the image file in PNG or JPEG format
4. Open your Word document, navigate to the Insert menu, and click on Pictures
5. Navigate to the folder where the image is saved and insert it into the document
6. Resize the image and position as needed

To use multiple signatures, you can scan and save each one to a separate file.

What is a Digital Signature?

The terms electronic signature and digital signature are used interchangeably. However, a digital signature is a special type of electronic signature that uses encryption and public-key cryptography to bind the signature to the document and verify the signer's identity.

A digital signature is like a digital fingerprint: it provides proof of the signer's identity and guarantees the document hasn't been tampered with.

Before you can use a digital signature, you must first obtain a digital certificate from a certificate authority (CA). This certificate and a public key are sent with your signed document and are used by the recipient's computer to verify your identity and the document's integrity.

How to Insert Digital Signatures in Word

Depending on your requirements, you can use Word's native features to add visible or invisible digital signatures to your documents.

How to Insert a Signature Line in Word 

Open the document, and place the pointer where you want to insert the signature line.

Go to the Insert tab, and click on "Microsoft Office Signature Line" in the Signature Line submenu.

Enter required information - including suggested signer's name, title, and email - in the Signature Setup dialog box, and select/unselect checkbox options to allow/disallow signer comments and sign date.

Click OK, and Word will insert a visible signature line.

To sign the document, double click on the signature line and type your name, sign using the inking feature, or insert an image of your handwritten signature.

A pop-up will appear if a valid certification is not available and you can follow the instructions to obtain one.

How to sign in Word by inserting an invisible signature

Another option you can use to protect the authenticity of your Word documents is to add an invisible signature. Rather than being displayed on the document, this type of signature is embedded within the document metadata.

1. Go to the File tab and click on Info
2. Click on Protect Document
3. Click on Add a Digital Signature
4. Click OK after reading the Word message
5. Type your purpose into the "Purpose for signing this document" box
6. Click on Sign

Managing Your Signature in Microsoft Word  

Documents often require signatures from multiple signatories for approval. And once signatures are created, a shortcut for inserting them helps speed up the process. Word provides features for managing multiple signatures and automatically inserting them into documents.

Adding signature in Word from multiple signatories

To add multiple signatures, simply repeat the process defined above for adding signature lines. You can repeat this process for as many signatories as required.

Automatically inserting signatures in documents

To create a reusable signature block, select the entire block and go to Insert > Quick Parts > Save Selection to Quick Part Gallery.

Name your signature and save.

Now, whenever you need to insert the signature block, go to Insert > Quick Parts and click your saved signature to insert it instantly.

Limitations of Signing Contracts in Microsoft Word  

Even though Word provides options for adding electronic and digital signatures and managing multiple signatures, it is not optimized for many business use cases. So, once you have learned the basics of how to put a signature on a Word document, consider these three limitations. 

1. No bulk signing feature for high-volume transactions

Adding signatures to contracts created in Word requires manual processing. While this is feasible for a limited number of documents, it becomes impractical when you have to create, sign, and deliver contracts in bulk.

2. Absence of version control can create confusion about the most up-to-date contract document

Business documents, such as proposals and contracts, are updated regularly. In legal and business contexts, working with outdated or incomplete drafts can invalidate contracts or cause financial/legal consequences.

Therefore, working with the most up-to-date document version is critical. Unless your documents are stored in OneDrive or a SharePoint Library, there is a serious risk of confusion and associated consequences if team members work on outdated contract versions.

3. Risk of non-compliance with e-sign standards and exposure to legal and compliance risks

E-sign standards, such as the ESIGN Act and UETA in the US and eIDAS Regulation in the EU, place strict requirements to ensure that digital signatures are valid, enforceable, and secure. The main requirements include proof of the signer's consent, verification of signatory identity, and methods for ensuring document integrity.

Word's basic signatures methods – drawn/typed names or pasted signature images – don't count as compliant signatures, and can expose businesses to legal and compliance risks. Therefore, using compliant e-signature solutions is a necessity, especially for businesses in regulated industries.
