What Is a Digital Signature? Meaning, Uses & Legal Validity
A digital signature is a modern way to sign documents electronically without printing or scanning paper. It is widely used across the world for contracts, forms, approvals, and online verification. Digital signatures help individuals and businesses sign documents securely and efficiently.
In this guide, you will learn what a digital signature is, how it works, where it is legally valid, and how you can create one easily using an online signature generator.
What Is a Digital Signature?
A digital signature is an electronic form of a handwritten signature that verifies the identity of the signer and confirms that the document has not been altered after signing. It is commonly used in digital documents such as PDFs, contracts, and online forms.
Unlike handwritten signatures, digital signatures can be created, shared, and stored electronically, making them faster and more convenient.
How Does a Digital Signature Work?
Digital signatures work by linking a signer’s identity with the document being signed. When a digital signature is applied, it confirms two things:
- The identity of the person signing the document
- The integrity of the document content
In simple terms, if a signed document is changed after signing, the digital signature becomes invalid. This helps maintain trust and security.
Digital Signature vs Handwritten Signature
Both digital and handwritten signatures serve the same purpose, but they are used differently:
- Handwritten signatures require printing, signing, and scanning
- Digital signatures can be applied instantly online
- Digital signatures are easier to store and share

For remote work and online transactions, digital signatures are far more practical.
