The two ways to sign a Word document

You can add your signature to a Word document in two ways: by inserting an image of your handwritten signature, or by using Word's built-in signature line feature. The image method is faster and works for most everyday documents. The signature line method creates a formal placeholder that shows you have signed the document and can include your printed name and title.

Which one you choose depends on what the document is for. If you're signing a contract that will be printed and mailed, or a document that needs to look officially signed, use the signature line. If you're just adding your signature to an email attachment or a document you're sharing digitally, inserting an image is simpler.

Key Takeaways

  • You can insert a scanned or photographed image of your handwritten signature directly into Word by going to Insert > Pictures and selecting your signature file.
  • Word's signature line feature creates a formal placeholder where someone can sign the document, and it shows whether the document has been signed.
  • To create a signature image, write your signature on paper, take a photo or scan it, save it as a file, and then insert it into your document.
  • Signature lines work best for documents that will be printed and signed by hand, while signature images work for documents shared digitally.

How to insert an image of your signature

Start by creating a digital image of your signature. Write your signature on a piece of white paper with a dark pen, then photograph it with your phone or scan it with a scanner. Save the image file to your computer — common formats like JPG or PNG work fine. Crop the image so it shows just your signature, not the whole page, to keep the file size small.

Open your Word document and click where you want the signature to appear. Go to the Insert tab at the top, then click Pictures and choose This Device. Find your signature image file and click Insert. The signature will appear in your document, usually larger than you want it. Right-click the image and select Wrap Text, then choose In Line with Text so it stays in place when you edit the document. Resize it by dragging the corner handles until it looks right.

Save your signature image somewhere you can find it again — many people keep a folder called "Signatures" on their desktop. Once you have it saved, you can insert the same signature into any document without recreating it.

How to add a signature line in Word

A signature line is a formal placeholder that shows where someone should sign a printed document. It includes space for a handwritten signature, the signer's printed name, and their title. Go to the Insert tab, then click Signature Line (you may need to look under Text or Explore More depending on your Word version). A dialog box will open.

Fill in the fields: Suggested Signer is the name of the person who will sign, Suggested Signer Title is their job title or role, and Suggested Signer Email is their email address. You can leave these blank if you want. Check the box that says Allow the signer to add comments in the Sign dialog if you want the person signing to be able to add a note. Click OK. Word will insert a signature line with a dotted line for the signature and space for the printed name below it.

Print the document and have the person sign it by hand on the dotted line. They can then write their name in the space below. If you want to sign it yourself, print it, sign it, and scan it back in.

Resizing and positioning your signature

If you inserted a signature image, you can make it larger or smaller by clicking it and dragging the corner handles. Drag from a corner (not the side) to keep the signature proportional. If you drag from the side, it will stretch and look distorted.

To move your signature to a different spot on the page, click it and drag it to the new location. If the signature keeps jumping around when you type, right-click it, select Wrap Text, and choose In Line with Text or Fixed Position on Page depending on whether you want it to move with the text or stay in one spot.

Saving a document with your signature

Once your signature is in the document, save it normally by pressing Ctrl+S (Windows) or Command+S (Mac), or by going to File and clicking Save. Word will save the signature as part of the document file.

If you plan to use the same signature in many documents, consider saving a blank template with your signature already in place. Go to File, click Save As, and change the file type to Word Template (the dropdown shows this option). Name it something like "Signature Template" and save it. The next time you need to sign a document, you can open this template, add your content, and the signature will already be there.

When to use each method

Use a signature image for most everyday documents — emails, PDFs you're sharing, digital forms, or any document that will stay on a screen. It's quick, looks professional, and the signature stays exactly as you created it.

Use a signature line for formal documents that will be printed and signed by hand, like contracts, agreements, or official letters. Signature lines are also useful if multiple people need to sign the same document in sequence, because Word can track who has signed and when. If you're sending a document to someone else to sign, a signature line makes it clear where they should sign and what information to include.

Frequently Asked Questions

Can I use a digital signature instead of typing my name?

Yes. A signature image (your handwritten signature photographed or scanned) serves the same purpose as typing your name and looks more personal. For most everyday documents, a signature image is sufficient. For legally binding documents, check with the other party about what they need — some contracts require a specific type of digital signature with encryption.

What if my signature image is too big or too small?

Click the signature image and drag the corner handles to resize it. Drag from a corner to keep it proportional. If it's still not the right size, you can go back to your original signature image file, crop it differently, and re-insert it into the document.

Can someone forge my signature if I use the same image in every document?

Yes — a signature image is just a picture, so anyone with access to it could copy it into their own documents. For everyday documents this is usually not a concern, but for important contracts or financial documents, ask the other party what level of security they need. Some situations require a certified digital signature with encryption rather than a simple image.

How do I remove a signature from a document?

Click the signature (image or signature line) and press the Delete key. If it's a signature line, the entire placeholder will be removed. If it's an image, just the image disappears and the rest of your document stays intact.

Can I add a signature to a document on my phone?

Word's mobile app lets you insert pictures, so you can add a signature image the same way you would on a computer. Signature lines work too, though the interface is slightly different. Open the document in the Word app, tap where you want the signature, go to Insert, and choose Pictures or Signature Line depending on what you need.
