✏️ Multiple Signature Methods
Create your signature by drawing with your mouse or touchpad, typing your name in a professional signature font, or uploading an image of your handwritten signature.
⚖️ Legally Binding
Your electronic signatures carry legal weight under ESIGN (US), eIDAS (EU), and similar regulations. Sign contracts, agreements, and official documents with confidence.

Automatically add date and time stamps to your signatures. Keep an audit trail showing when the document was signed.
Electronic Signatures vs. Handwritten Signatures
Electronic signatures (e-signatures) created with SwiftTools are legally equivalent to handwritten signatures in most contexts. They fulfill the same legal purpose by proving your intent to sign and authenticate a document. Unlike handwritten signatures on paper, e-signatures offer several advantages: they're timestamped, they can't be forged through photocopying, they work across devices, and they're audit-tracked.
However, not all documents can be legally signed electronically. Some jurisdictions exempt notarized documents, wills, powers of attorney, and certain government forms from e-signature acceptance. Always verify your local laws before signing critical documents electronically.
Use Cases for PDF Signing

PDF Signature: Frequently Asked Questions
Are electronic signatures legally binding?
Yes, electronic signatures are legally valid in most jurisdictions, including the United States (ESIGN Act), European Union (eIDAS Regulation), and many other countries. A signature made with SwiftTools on a PDF carries the same legal weight as a handwritten signature, provided it meets the legal requirements: intent to sign, authentication, and non-repudiation. Always verify your local laws for specific requirements, especially for critical documents like contracts, wills, or medical records.
Can I send a PDF for others to sign?
SwiftTools Sign PDF lets you add your own signature to documents. To collect signatures from multiple signers, you can save the signed PDF and send it via email, cloud storage, or messaging apps to other signers. Each person can download the file, add their signature using SwiftTools, and send it to the next person. Alternatively, consider dedicated e-signature platforms like DocuSign or Adobe Sign for workflows requiring signature tracking and audit trails.
How do I create a signature to use on PDFs?
SwiftTools offers three convenient ways to create your signature: (1) Draw your signature using your mouse or touchpad by drawing directly on the canvas. (2) Type your name in a professional signature font that mimics a handwritten style. (3) Upload an image of your existing handwritten signature. Choose whichever method feels most natural and authentic to you. Once created, you can save your signature and reuse it on future documents.
