The fastest way to make an electronic signature in Word is to insert a picture of your signature onto the signature line of the document, or use Word's built-in Signature Line feature to mark where a signature goes. Both put marks on a page. Neither one, by itself, creates a record of who signed or when, and that matters more than most people expect once a signed document is questioned. This guide covers both Word methods and their limits, then the path to a signed document that holds up: upload the Word file to GSD and send it for e-signature directly, with no PDF conversion.
Method 1: Insert a signature image into Word
This is the method most people already use for internal memos, informal approvals, or documents they don't expect anyone to challenge.
- Create a signature image. Sign a blank piece of paper and scan or photograph it, or draw your signature directly on a touchscreen. If you'd rather skip the scanning, GSD's free signature generator lets you draw or type a signature in your browser and download it as an image. No account needed.
- Insert it into your document. In Word, place your cursor where the signature should go, then insert the image file from your computer.
- Resize and position it. Drag the image's corner handles to scale it, and use Word's text-wrapping options if you need the signature to sit inline with a signature line or date field.
- Save and share the file. Save the document and send it to whoever needs a copy.
This produces a document that looks signed. That's all it does.
Method 2: Word's Signature Line feature
Current versions of Microsoft 365 include a Signature Line feature (under the Insert tab) that adds a formatted line with an X, a name placeholder, and a title placeholder, the usual look of a signature block. It's a formatting tool. It marks where a signature belongs and makes the document look professional, but it doesn't verify identity or generate a tamper-evident record on its own. Some configurations support attaching a digital certificate to a signature line. That's a separate, more technical capability that most small businesses never set up and shouldn't need for everyday contracts.
We're deliberately not walking through every menu and submenu here. Microsoft moves things around inside Word from time to time, and the useful part of this feature is the idea (a formatted placeholder for a signature), not the exact click path.
Why a pasted image isn't an auditable e-signature
A picture of a signature dropped into a Word document is indistinguishable from a picture of anyone's signature. There's no timestamp tied to the signing action, no record of whose device or email address was used, and nothing stopping someone from copying that image into a different document entirely. If a signed contract is ever disputed, the other side can plausibly claim they never saw the document, never agreed to it, or that someone else pasted their signature in.
The ESIGN Act makes electronic signatures legally valid in the US, but validity isn't the same as provability. ESIGN defines an electronic signature as a sound, symbol, or process attached to a record and executed or adopted by a person with the intent to sign (see the definition at 15 U.S.C. §7006(5)). The legal concept underneath that definition is attribution: being able to show that a specific person, at a specific time, intended to sign. A signature image with no metadata behind it gives you the mark but no proof of who made it or when. If the other party denies signing, you have very little to point to.
So there's "an electronic signature," and there's "an electronic signature you can prove in a dispute." For anything with real money, liability, or a relationship on the line (contracts, service agreements, offer letters, waivers), you want the second kind. Both are also different from a certificate-based digital signature; if you're unsure which term applies to your situation, see electronic vs. digital signature.
The practical fix: send the Word document for signature
You don't need to convert your document to a PDF or rebuild it in another tool. GSD accepts Word documents (.docx) directly. Upload the file, and GSD's AI places signature, date, and text fields on the document automatically. You review the placement, adjust anything you want, add your signer's email address, and send. Your signer opens a link in their browser, on a phone or a computer, and signs. They don't need a GSD account, an app, or any download.
When they finish, you get back the completed document with a tamper-evident audit trail: a SHA-256 hash of the final file, each signer's IP address, and timestamps for every step, plus a Certificate of Completion. That's the record the pasted image was missing, showing who signed, when, and that the file hasn't been altered since. If your document is already a PDF rather than a Word file, the same process is covered step by step in how to send a PDF for signature, and you can read more about what goes into that record in how an audit trail holds up as evidence.
GSD's Free plan covers 5 documents a month with no credit card required, which is plenty for occasional use. Paid plans add unlimited documents, templates, and team seats if you're sending regularly.
Frequently asked questions
Is a signature image pasted into Word legally binding?
It can be, since the ESIGN Act doesn't require any particular technology. But "legally valid" and "easy to defend if challenged" are different things. Without a record of who signed and when, you may struggle to prove the signature is real if the other party disputes it.
Does Word have a real e-signature feature?
Word's Signature Line is a formatting element that marks where a signature goes. It isn't an e-signature platform and doesn't produce an audit trail or Certificate of Completion the way a dedicated e-signature tool does.
Can I send a Word document for signature without converting it to a PDF?
Yes. GSD accepts .docx files directly, so there's nothing to convert or reformat before uploading.
What's the difference between an electronic signature and a digital signature?
An electronic signature (what GSD provides) is any signature process with an audit trail behind it. A digital signature specifically refers to certificate-based cryptographic signing (PKI). See electronic vs. digital signature for the full breakdown.
Do my signers need a Word or Microsoft 365 account to sign?
No. Once you send a document through GSD, signers open a link in any browser and sign. They don't need an account, an app, or a Microsoft 365 subscription.
