Sign PDF on Mac
Preview's trackpad signature is famous for looking nothing like your signature. The browser signing adds the options that fix it — type it styled, or upload a photo of the real thing — then places it precisely. Free with fair daily limits.

The trackpad problem
Signing your name with a finger on a trackpad produces a wobbly stranger's mark — Preview's camera capture helps but fights lighting and paper. Uploading a clean photographed signature, or typing a styled one, lands professional every time.
The signing session
Upload the contract, create the signature your way, place and size it on the line, add the date, download — the signed copy is ready for reply-all before Preview's camera would have focused.
