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.
Signature Editing
Change signature ink colors to match document themes or corporate branding. Remove paper backgrounds to create transparent PNGs that blend seamlessly with any document. Enhance contrast and sharpness on faded or low-quality signature images.
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
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.
