How to Sign a PDF Online for Free

Need to sign a PDF but don't want to print, sign, and scan? You're not alone. Millions of people search for free ways to sign PDFs online every month.

In this guide, we'll show you exactly how to sign any PDF document online — completely free, no software download required.

What You Need

• A PDF document to sign
• A web browser (Chrome, Firefox, Safari, Edge)
• An internet connection

That's it. No desktop software, no app download, no account required for basic signing.

Method 1: Sign a PDF with SignQuick (Recommended)

SignQuick lets you sign PDFs online for free with a generous 5-document monthly limit.

Step 1: Upload Your PDF

Go to signquick.app and click "Get Started Free." Upload your PDF by dragging and dropping or clicking to browse.

Step 2: Add Your Signature

You have three options:

• Draw your signature using your mouse, trackpad, or finger on mobile
• Type your name and choose from signature fonts
• Upload an image of your existing signature

Step 3: Place and Resize

Drag your signature to the right position on the document. Resize it to fit the signature line.

Step 4: Download

Click "Complete" and download your signed PDF. The signature is embedded in the PDF — it can't be moved or edited.

Method 2: Sign on Your Phone

SignQuick works perfectly on mobile browsers. If someone sends you a signing link:

• Open the link on your phone
• Draw your signature with your finger
• Tap "Sign" — done

You can also scan a QR code to sign on your phone while viewing the document on your computer.

Method 3: Send a PDF for Others to Sign

Need someone else to sign your document?

• Upload the PDF to SignQuick
• Add signature fields where each person needs to sign
• Enter their email addresses
• Click "Send" — they'll receive an email with a secure link

Signers don't need an account. They click the link, sign, and you get notified instantly.

Is a Free Online Signature Legally Valid?

Yes. Electronic signatures are legally binding in most countries:

• United States — ESIGN Act (2000) and UETA
• European Union — eIDAS Regulation
• United Kingdom — Electronic Communications Act
• Canada — PIPEDA and provincial laws
• Australia — Electronic Transactions Act

Every document signed on SignQuick includes a complete audit trail recording who signed, when, and from which IP address.

Free vs Paid: What's the Difference?

For most personal use, the free plan is more than enough.

Tips for a Good Digital Signature

• Use your real name — consistency matters for legal documents
• Sign on a tablet or phone for the most natural-looking signature
• Save your signature (on a paid plan) so you don't have to redraw it every time
• Check the document before signing — once signed, changes create a new version
