Why Sign PDFs Electronically?

Gone are the days of printing, signing, and scanning documents. Electronic signatures save time, paper, and hassle:

  • Speed: Sign documents in seconds instead of hours
  • Convenience: Sign from anywhere on any device
  • Cost savings: No printing, scanning, or postage needed
  • Environmental impact: Reduce paper waste significantly
  • Legal validity: Electronic signatures are legally binding in most countries

Whether you are closing a business deal, accepting an offer letter, or signing a rental agreement, electronic signatures streamline the entire process. According to industry research, organizations that adopt e-signatures reduce document turnaround time by up to 80%.

Understanding Electronic vs. Digital Signatures

Before diving in, it helps to understand the distinction between electronic signatures and digital signatures:

  • Electronic signatures are any mark, symbol, or process attached to a document that shows intent to sign. This includes typed names, drawn signatures, and uploaded images.
  • Digital signatures use cryptographic certificates to verify identity and ensure the document has not been tampered with after signing.

For most everyday use cases such as contracts, NDAs, and internal approvals, a standard electronic signature is sufficient and legally binding.

Types of Electronic Signatures

Typed Signatures

Type your name in a stylized font. Quick and easy for informal documents like internal memos, acknowledgment forms, and routine approvals.

Drawn Signatures

Draw your signature using your mouse, trackpad, or touchscreen. Most closely resembles a handwritten signature and is the preferred choice for formal agreements and client-facing documents.

Uploaded Signatures

Upload an image of your actual handwritten signature. Ideal for professional documents where you want your exact signature reproduced perfectly, such as executive letters and legal filings.
