The three types of PDF signatures
There are three different types of PDF signatures — understanding the difference matters before you choose a tool:
1. Typed signature — your name typed in an italic or cursive font and embedded in the PDF. Fast, free, but not legally binding for formal contracts.
2. Drawn signature — you draw your signature with a mouse or finger on a touchscreen. More personal than typed but still not legally binding.
3. Legally binding e-signature — verified digital signature with audit trail, identity verification, and legal standing (DocuSign, Adobe Sign, HelloSign). Required for contracts, legal documents, employment agreements.

For informal documents — approval forms, HR documents, internal sign-offs — a typed signature is sufficient.

Use a proper e-signature service for:
- Employment contracts
- Business agreements and NDAs
- Real estate documents
- Legal settlements
- Financial agreements
- Any document where you need a verifiable audit trail
Free e-signature options:
