How to Create an Electronic Signature: Free, Any Document (2026)

An electronic signature lets you sign contracts, forms, and agreements without printing, scanning, or paying for a subscription service. You can create one in minutes and apply it to any PDF. Here's how to make an electronic signature for free, and keep your documents private while you do it.

What Counts as an Electronic Signature?

An electronic signature is any mark you apply to a document to show intent to sign: a typed name, a drawn signature, or an image of your handwriting. A digital signature is a specific, more secure type that uses a certificate to verify your identity and prove the document wasn't changed after signing. For everyday agreements, an electronic signature is accepted and legally valid in most countries.

Create and Apply Your Signature (Free, No Upload)

PDF Zone's Sign PDF tool lets you create a signature and place it on a document right in your browser, the file never leaves your device.

1. Open the Sign PDF tool.
2. Upload the PDF you need to sign.
3. Create your signature one of three ways:
   • Draw it with your mouse, trackpad, or finger on a touchscreen.
   • Type your name and pick a signature-style font.
   • Upload a photo of your handwritten signature.
4. Drag the signature onto the page and resize it.
5. Download the signed PDF.

That's it: a reusable electronic signature, applied without printing anything.

Make a Clean Signature Image

If you prefer to use a real handwritten signature:

1. Sign your name on white paper with a dark pen.
2. Photograph or scan it (your phone's scanner works well).
3. Save it as a PNG with a transparent background so it drops cleanly onto any document.
4. Upload it in the Sign PDF tool.

A Free Alternative to DocuSign

Services like DocuSign are built for sending signature requests to other people, but for simply signing a document yourself they're overkill, and they upload your file to their servers. If you just need to sign and send back a PDF, the Sign PDF tool does it instantly, for free, with no account and no upload. You keep full control and privacy.

Signing in Word Instead?

If your document is in Microsoft Word and you want the signature there, see our dedicated guide on creating an electronic signature in Word. For the most reliable, tamper-resistant result, though, export to PDF and sign the PDF, the signature stays fixed in place for every recipient.

Lock It Down After Signing

Once signed, prevent further changes:

• Flatten the PDF so the signature can't be moved or edited.
• Encrypt the PDF with a password before sharing.
