Digital Signatures for Documents
Digital signatures add personal authentication to electronic documents. While different from cryptographic signatures (which verify document integrity), visual signatures serve important roles in contracts, forms, and official correspondence.
Types of Digital Signatures
Drawn signatures use mouse, trackpad, or touchscreen input to capture natural handwriting motion. These most closely resemble traditional pen signatures and are widely accepted for informal documents.
Typed signatures render your name in script or cursive fonts. They're faster to create and highly legible, making them suitable for professional documents where aesthetics matter.
Uploaded signatures digitize existing paper signatures. Scan or photograph your handwritten signature, then process it for transparent backgrounds and clean edges.
Technical Requirements
- Transparent background: Essential for overlaying on documents
- High resolution: At least 300 DPI for printed documents
- PNG format: Supports transparency and lossless quality
- Consistent sizing: Standard dimensions for repeated use
Legal Considerations
Electronic signatures are legally binding in most jurisdictions under laws like ESIGN (US) and eIDAS (EU). However, some documents (wills, certain real estate transfers) still require wet signatures. Always verify requirements for legally significant documents.
