How to Create an Electronic Signature (5 Free Methods)

You don't need expensive software to create an electronic signature. You don't even need an account with some big-name platform. Whether you're signing a freelance contract, a rental agreement, or an NDA, there are several ways to get your signature onto a digital document without spending a dime.

In this guide, you'll learn exactly how to create an electronic signature using five different methods, from dead-simple (typing your name) to more advanced (digital certificates). We'll cover what works on your phone, what's legally valid, and when you actually need a paid tool versus when free options do the job just fine.

What Is an Electronic Signature?

An electronic signature is any electronic mark, sound, or process that a person attaches to a document to indicate their intent to sign. That definition is intentionally broad. A typed name at the bottom of an email can count. A checkbox on a web form can count. A finger-drawn squiggle on your phone screen definitely counts.

Electronic signatures are different from digital signatures, which use cryptographic certificates to verify identity. If you want to understand the distinction in detail, check out our guide to digital signatures vs. electronic signatures. For most contracts, a standard electronic signature is all you need.

5 Ways to Create an Electronic Signature

Not every situation calls for the same approach. Here's a comparison of the five most common methods to create an electronic signature, with the pros and cons of each.

Let's break down each method.

1. Type Your Name as a Signature

The simplest online signature maker approach. Many tools and PDF readers let you type your name and pick a script-style font that looks like handwriting. It takes about five seconds.

How to do it: Open your document in a PDF reader like Adobe Acrobat Reader (free), click the signature tool, select "Type," enter your name, and choose a font style. Place it where needed.

The catch: It works, but it looks generic. Every "Jessica Smith" in the same font looks identical, which might feel impersonal for important contracts. Legally, though, it's perfectly valid.

2. Draw Your Signature with a Mouse or Finger

This gives your electronic signature a personal touch. You draw it freehand using your mouse on a computer or your finger on a touchscreen device.

How to do it: Most PDF readers and e-signature tools offer a "Draw" option. Click it, draw your signature on the canvas, and place it on the document. On a phone or tablet, use your finger or a stylus.

The catch: Drawing with a mouse is awkward. Your signature will probably look shaky unless you practice. A touchscreen with a stylus produces much better results.

3. Upload a Scanned Signature Image

If you have a distinctive signature you want to preserve exactly, sign a blank white piece of paper with a dark pen, photograph it, and crop the image. You can then place this image on any document.

How to do it:

1. Sign your name on white paper with a black pen
2. Take a photo with your phone (good lighting, no shadows)
3. Crop the image tightly around the signature
4. Save as PNG with a transparent background if possible
5. Insert the image into your document

The catch: Without a transparent background, you'll have a white box sitting on top of your document. And someone could theoretically copy your signature image, so this method works best for low-risk documents.

4. Use a Digital Certificate (PKI)

A digital certificate links your identity to a cryptographic key pair. When you sign a document with a certificate, the signature is mathematically tied to your verified identity, and any tampering with the document after signing is detectable.

How to do it: Purchase a digital certificate from a trusted Certificate Authority (like DigiCert, GlobalSign, or a government-approved provider). Install it on your computer. Use a PDF editor that supports certificate-based signatures, like Adobe Acrobat Pro.

The catch: This is the most secure option, but it's expensive and complicated for everyday use. You need it for qualified electronic signatures under eIDAS or certain government filings. For a typical business contract, it's overkill.

5. Use an Online Signature Tool

Online tools combine convenience with proper documentation. You upload your document, add signature fields, sign or send it for signing, and get a completed PDF with a full audit trail (timestamps, IP addresses, email verification).

How to do it with CanUSign: Upload your PDF, place signature fields, sign it yourself or send a link to others, and download the finished document. No account needed for signers.

The catch: Some tools charge per signature or require monthly subscriptions. Free tiers often limit the number of documents you can send. But for anything that matters, having a proper audit trail is worth it.

How to Create an Electronic Signature Online (Step-by-Step)

Here's the exact process for creating an electronic signature and signing a document using an online tool. We'll use CanUSign as the example, but the workflow is similar across most platforms.

Step 1: Upload Your Document

Go to canusign.com/create and upload your document. PDF is the most common format, but most tools also accept Word documents (.docx), which get converted to PDF automatically.

You can also start from scratch by creating a new document directly in the tool if you don't have a file ready.

Step 2: Add Signature Fields

Drag and drop signature fields onto the document where signatures are needed. If multiple people need to sign, assign each field to a specific signer by entering their name and email address.

You can also add other field types:

• Date fields that auto-fill when signed
• Text fields for names, titles, or other information
• Checkbox fields for agreement confirmations
• Initial fields for page-by-page acknowledgment

Step 3: Sign or Send for Signing

If you're the only signer, apply your signature right away. Choose your preferred method: type it, draw it, or upload an image.

If others need to sign, click send. Each signer receives an email with a unique link to the document. They can review and sign from any device without creating an account. You'll get notified as each person signs.

Step 4: Download the Signed Document

Once everyone has signed, you'll receive the completed document as a PDF. The file includes all signatures plus an audit certificate showing:

• Who signed and when
• Email addresses used
• IP addresses
• The order signatures were applied

This audit trail is what makes online e-signatures more verifiable than a scanned handwritten signature.

How to Create an Electronic Signature on Your Phone

You don't need a computer. Here's how to create an electronic signature on your phone using three different approaches.

Method A: Use your phone's built-in markup tools

On iPhone, open a PDF in the Files app, tap the markup icon (pen tip), tap the "+" button, and select "Signature." Draw with your finger and place it. On Android, Google Drive's PDF viewer has a similar annotation feature, though it's more limited.

Method B: Use a mobile e-signature app

Apps like CanUSign, DocuSign, or Adobe Sign have mobile-optimized interfaces. Open the signing link on your phone, and the experience is designed for touchscreens. Drawing your signature with your finger on a phone screen actually feels more natural than using a mouse.

Method C: Use your phone's camera

Sign a piece of paper, photograph it, crop it, and insert the image into your document. This works in a pinch but lacks the audit trail that a proper e-signature tool provides.

Pro tip: If you sign documents regularly on your phone, save your signature in your phone's settings or in your preferred app. Both iOS and Android remember signatures you've drawn, so you only need to create it once.

Is an Electronic Signature Legally Valid?

Yes. In almost every country, electronic signatures carry the same legal weight as handwritten ones for most types of contracts.

The two major legal frameworks are:

1. The ESIGN Act (United States, 2000): States that a signature cannot be denied legal effect solely because it's in electronic form. Covers most commercial and consumer transactions. Full text here.

2. eIDAS Regulation (European Union, 2014): Establishes three tiers of electronic signatures (simple, advanced, and qualified) and ensures cross-border recognition within all EU member states.

Most other countries, including Canada, Australia, Brazil, Japan, South Korea, and India, have similar laws recognizing electronic signatures.

Exceptions where electronic signatures may not be accepted:

• Wills and testaments (most jurisdictions)
• Real estate deeds (varies by state/country)
• Court orders and notarized documents
• Certain family law documents (adoption, marriage)

Free vs. Paid E-Signature Tools: An Honest Comparison

You can create an electronic signature for free. But should you? It depends on what you're signing.

When free tools are enough:

• Signing a document just for yourself (no need to send it)
• Low-stakes agreements where an audit trail isn't critical
• One-off signatures where you won't need to track the document later
• Personal documents like permission slips or internal memos

Free options include: Adobe Acrobat Reader (sign only, can't send for signature), Apple Preview on Mac, Google Docs (limited), and various online PDF editors.

When you should use a paid tool:

• Contracts involving money or legal obligations
• Documents that need multiple signers
• Situations where you need proof of who signed and when
• Business use where you send contracts regularly
• Any document you might need to defend in court

What paid tools add: Audit trails, signer authentication, automated reminders, templates, team management, and legal compliance documentation. These features don't matter until they do, and when they do, they matter a lot.

CanUSign sits in a practical middle ground. You pay per signed document (starting at EUR 1) instead of a monthly subscription, which makes sense if you're not signing hundreds of documents per month. No subscription to cancel if you don't use it for a few months.

FAQ

How do I create an electronic signature for free?

The quickest free method is using a PDF reader like Adobe Acrobat Reader. Open your PDF, click "Fill & Sign," then "Sign Yourself." You can type, draw, or upload a signature image. This works for signing documents yourself but doesn't include sending documents to others for signature or generating audit trails.

Is a typed name a valid electronic signature?

Yes. Under both the ESIGN Act and eIDAS, a typed name counts as a valid electronic signature as long as the signer intended it as their signature. The legal validity depends on intent, not on how the signature looks. That said, using an e-signature platform adds an audit trail that makes the signer's intent much easier to prove.

How do I add an electronic signature to a PDF?

Open the PDF in any PDF reader with signing capabilities (Adobe Acrobat Reader, Apple Preview, or an online tool like CanUSign). Look for a "Sign" or "Fill & Sign" option. Create your signature by typing, drawing, or uploading an image, then click on the spot in the PDF where you want to place it. Save the file.

Can I create an electronic signature on my iPhone or Android?

Yes. On iPhone, open any PDF in the Files app or Mail, tap the markup tool, and select "Signature." On Android, use Google Drive or a dedicated e-signature app. You can also open a web-based tool like canusign.com/create in your mobile browser, which works on any device without installing an app.

What's the difference between an electronic signature and a digital signature?

An electronic signature is any mark indicating intent to sign, including typed names, drawn signatures, or clicked checkboxes. A digital signature is a specific type that uses cryptographic certificates to verify identity and detect document tampering. Digital signatures are a subset of electronic signatures. Most everyday contracts only require a standard electronic signature.
