The Easiest Way to Sign PDFs Online

Need to sign a PDF quickly? Our free online PDF signature tool lets you add your electronic signature to any document in seconds. Whether you're signing contracts, agreements, forms, or applications, you can do it all right from your browser—no software installation needed.

Traditional paper signing is slow and inconvenient. You have to print, sign by hand, scan, and email back. With our electronic signature tool, you can complete the entire process in under a minute, all digitally.

Why Use Our PDF Signature Tool?

  • Quick Signing: Add your signature with your mouse, trackpad, or finger on touchscreen devices.

  • Multiple Signatures: Add multiple signatures to the same document if needed.
  • Type or Draw: Create your signature by drawing it freehand or typing your name in a signature font.
  • Secure Processing: Your documents are encrypted and never stored on our servers after signing.
  • Mobile Friendly: Sign PDFs on your smartphone or tablet with ease.

When to Use Electronic Signatures

Our PDF signer tool is perfect for:

  • Business contracts and agreements

  • Purchase orders and invoices
  • Permission slips and consent forms
  • Bank and financial documents

Are Electronic Signatures Legal?

Yes! Electronic signatures are legally recognized in most countries. In the United States, the ESIGN Act (2000) and UETA make electronic signatures as legally binding as handwritten ones. The EU's eIDAS regulation provides similar legal framework in Europe. Most businesses and government agencies accept electronic signatures.

Our tool creates signatures that are widely accepted for everyday business documents, contracts, and forms. For highly sensitive legal matters, you may want to consult with legal counsel about signature requirements.

Free Alternative to DocuSign and Adobe Sign

Services like DocuSign and Adobe Sign charge expensive monthly fees for basic document signing. Our free PDF signature tool gives you the same core functionality without any cost. Sign as many documents as you need, whenever you need, completely free.

While paid services offer advanced features like signature tracking and team management, most individuals and small businesses only need simple signature functionality—which we provide for free.

Security & Privacy

We take your document security seriously. All PDFs are processed using secure HTTPS connections. Your documents are never permanently stored on our servers—they're automatically deleted after processing. We never access, read, or share your documents with third parties.
