Signing documents properly
A drawn or typed signature on a PDF is accepted for many everyday documents, such as offer letters, rental forms, delivery notes and internal approvals. Some official processes need a certified digital signature or a wet-ink signature instead, so check what the receiver asks for.
- On a phone, draw slowly with a finger or stylus. It usually looks more natural than a signature drawn with a mouse.
- For a crisp copy of your paper signature, sign on plain white paper with a dark pen, photograph it in good light and upload the photo.
- Add the date next to your signature, and initial each page if the document asks for it.
- Sign last: make text changes first in Edit PDF, then sign, then compress if the file is too big.
