How do I fill in and sign a PDF for free?
The free way to fill in and sign a PDF is the reader you already have. Adobe Acrobat Reader (free), Mac Preview and Microsoft Edge all fill forms and add a drawn or typed signature without paying. Online "e-sign" sites usually limit free signatures and ask for an account.

Good to know
- In Edge, open the PDF and use Draw or Add text. Save, then send.
- For contracts that need a legal audit trail, the other side usually sends you a DocuSign link. You do not need your own account to sign it.
