Today, Mytour will guide you on using the Signature Line tool in Microsoft Word to insert a digital signature into your document on a Windows computer. Alternatively, you can convert the file to PDF format and add a signature using the Preview application on a Mac.
Steps
On Windows

Open the document in Microsoft Word. Double-click the Word document where you want to add the signature.
- If you want to start a new document, open Microsoft Word and click File, then select New Document.

Click on the Insert tab at the top of the window.

Click on Signature Line in the toolbar, located above the Text section of the Insert ribbon.

Click on Microsoft Office Signature Line.
- If the document hasn't been saved yet, first click on File, select Save As, then name the file and click Save.

Add signature details. Enter the information that will appear below the signature line in the Signature Setup dialog box, such as name, title, email address, and any other instructions you want to leave for the signer. You can also:
- Check the Show sign date in signature line box if you want the signing date to be automatically inserted.
- Check the Allow the signer to add a comment in the Sign dialog box box if you want to enable comments for anyone signing the document.

Click OK.

Right-click on the signature line and select Sign.

Type your name next to the X mark.
- If you have a scanned image of your handwritten signature, click on Select Image, then choose the file containing your signature image.

Click on Sign. A "signature" indicator will appear near the word count at the bottom of the document, indicating that the document has been signed.
On Mac

Open the document in Microsoft Word. Double-click the Word document where you want to add the signature.
- If you want to start a new document, open Microsoft Word and click File, then select New Document.

Click on File at the top-left corner of the menu bar and select Save As.

Click on the "File Format" dropdown menu and choose PDF.

Click on Save.

Open Finder and navigate to the file you just saved. Finder has a blue and white face icon located at the bottom-left corner of the dock.

Right-click on the PDF file and select Open With, then click on Preview. The PDF file will open in the Preview application.

Click on the toolbox icon located to the left of the search bar.

Click on the Signature task, which looks like a handwritten signature on a small line, positioned to the right of the "T" icon.

Click on Trackpad or Camera. If your laptop uses an integrated or external trackpad, you can click on Trackpad. If you don’t have a trackpad but have a webcam, choose Camera.

If the digital signature has already been saved, you may need to click on Create Signature first.

Create your signature.
- For Trackpad:
- Click on Click Here to Begin.
- Use your finger to draw your signature on the trackpad.
- Press any key on the keyboard.
- Click on Done.
- For Camera:
- Sign your name on a blank sheet of paper.
- Hold the paper up to the camera.
- Align the signature properly.
- Click on Done.

Click on the newly created signature in the dropdown menu. Your signature will appear in the middle of the document.

Drag the mouse to reposition the signature. Click and hold the center of the signature, then drag it to the desired location.
- You can resize it by clicking and dragging the corners of the signature inward or outward.

Click on File and select Save. The document with your digital signature will be saved.
