Signing PDF documents electronically
Signing a PDF electronically is faster than printing, signing by hand and scanning, and it works well for everyday documents like agreements, forms and letters that need a personal signature. You can draw a signature with your mouse or finger, type your name in a script style font, or upload an image of your handwritten signature.
Electronic signatures are widely accepted for many everyday and business documents in many countries, but rules on when an electronic signature is legally sufficient vary by jurisdiction and document type, so it's worth checking local requirements for anything with significant legal weight, such as certain contracts or official filings. The signed PDF keeps the same page layout and a similar file size to the original.
Documents are transferred over an encrypted connection and deleted automatically after processing, and no account is required to sign a file.
