How to add a signature in Word (Windows, Mac, and mobile)

Adding an electronic signature in Microsoft Word is possible, but it’s not exactly the smoothest experience. It can be tricky to set up, doesn’t always look professional, and isn’t the most user-friendly option for your recipients. 

Creating an electronic signature in Word might seem convenient because it’s a free “solution,” but it’s not built for modern e-sign workflows. Features like tracking, automation, and secure sharing simply aren’t built in. 
In this article, I’ve shared how to insert different types of electronic signatures in Word. I’ve also provided an alternative that makes the whole process faster, easier, and more polished for everyone involved.

How to insert a signature in Word for Windows

Here are three common ways you can insert an e-signature in Word using Windows.

1. Insert a picture of your handwritten signature

Inserting a picture of a handwritten signature is one way to insert an electronic signature in Word. It’s actually how I used to add signatures to documents back in my early career (about 15 years ago). It’s adequate, but it’s old-school.

Here’s how you do it:

1. Sign your name on white paper using a dark pen.
2. Scan or photograph it, then save it on your PC as a .png or .jpg file.
3. Open your Word document and place your cursor where the signature should go.
4. Go to Insert > Pictures > This Device and select your image.
5. Click Insert, then (optionally) use the Picture Format tab to crop out any excess background.

2. Add a built-in signature line

The built-in signature line creates a formal, designated space for someone to sign your document after printing:

1. Click where you want the signature line to appear.
2. Go to Insert > Signature Line (found in the Text menu).
3. Select Microsoft Office Signature Line.

4. In the dialog box, fill in the signer’s name, title, and email address if needed.
5. Click OK. A signature line with an X placeholder will appear in your document.

Note that once the signature line is created, it can’t be edited — you’ll need to delete it and recreate it if you make a mistake. You also can’t click and sign like an e-signature. The document needs to be printed and signed using a wet signature. Read about electronic vs wet signatures for more information about the differences.

3. Use an add-in

Because Word’s built-in e-signature options are limited for real signing workflows, add-ins that allow you to add a digital signature for Word documents bridge the gap. You can connect Word to dedicated e-signature apps.

Here’s how you do it:

1. Open your Word document. Go to the Home tab and click the Add-ins icon (four red squares).
2. Search for “signature.”
3. Popular options include Dropbox Sign, Sign.Plus, and Docusign. Select one and click Add.
4. Follow the add-in’s prompts to log in and send your document for signing.

How to insert a signature in Word for Mac

This next process explores how to add a signature line in Microsoft Word on Mac. It’s similar to the Windows workflow. 

1. Insert a picture of your handwritten signature

This works much the same as on Windows and lets you insert your signature to sign a Word document on a Mac.

1. Sign your name on white paper using a dark pen.
2. Scan or photograph it, then save it on your Mac as a .png or .jpg file.
3. Open your Word document and place your cursor where the signature should go.

1. Go to Insert > Pictures > Picture from File. Find your signature image.
2. Click Insert, then (optionally) use the Picture Format tab to crop out any excess background.

2. Use an add-in

Just like on Windows, Mac users can add e-signatures for Word through Office add-ins.

1. Open your Word document and go to Insert > Get Add-ins.

2. Search for “signature” in the store.
3. Select a compatible add-in, and click Add.
4. Follow the add-in prompts to authenticate and send your document for signing.

How to sign Word documents on mobile (iOS and Android)

Word’s mobile app lets you create and e-sign on a phone, but the experience is more limited than on a desktop, especially when it comes to drawing or managing signatures on a small screen.

Signing Word documents on iOS

Here’s the workflow for signing Word documents in iOS:

1. Open the Word app on your iPhone or iPad and navigate to the document you want to sign.
2. Tap the Edit icon (pencil) to enter editing mode.
3. Tap where you want your signature to appear.
4. Go to Insert > Pictures and select a saved image of your signature from your photo library.
5. Tap the image to resize and reposition it as needed.
6. Tap Done to save your changes.

Signing Word documents on Android

1. Open the Word app on your Android device and open the document you want to sign.
2. Tap the Edit icon to enter editing mode.
3. Tap where you want your signature to appear.
4. Tap Insert > Pictures and choose a saved signature image from your gallery.
5. Tap the image to adjust its size and position.
6. Tap Done to save.

Word’s mobile app has real limitations. It doesn’t support advanced signature line features, and drawing on a tiny screen is awkward. If you regularly need to collect signatures from others or manage multiple documents, Jotform Sign Mobile is a purpose-built alternative. Use the free document signing app, available on iOS and Android, to scan physical paper directly into a signable PDF or use in-person signing to collect client signatures on a tablet or phone.

How to automate signatures with Jotform Sign

Word is a great word processor, and it’s fine for collecting e-signatures if you seldom do it. But if you’re regularly sending documents for signature, chasing people for updates, managing multiple signature workflows, or manually filing completed forms, there’s a better way: Consider Jotform Sign vs Word signatures.
