What is eSign?
eSign is a short term for electronic signature. This is the digital alternative to a handwritten signature. It allows users to sign documents electronically using a mouse, stylus, keyboard, or an uploaded image of their signature. This makes it easier than ever to fill and sign PDF online, eliminating the need to print, scan, or physically mail documents.
While many confuse eSignatures with digital signatures, they are slightly different. An eSign is a broad term for any electronic agreement mark, while a digital signature uses encryption to verify the signer’s identity and ensure document security.
Electronic signatures are legally recognized in many parts of the world, including under laws like the U.S. E-SIGN Act and the EU’s eIDAS regulation. They’re widely used in business contracts, job offers, lease agreements, and application forms.
Using eSign to fill and sign PDFs online offers many benefits: it’s faster, more convenient, secure, and environmentally friendly.
