- How to make a transparent signature imageCreate a signature PNG with a genuinely transparent background — by drawing it directly, or by cleaning up a photo of a signature on paper.
- How to fill out and sign a PDF formFill a PDF form and sign it in one pass — with real form fields or with a flat scanned form — plus the checks that stop a form from being sent back.
- Signing a contract you received by emailFrom inbox to signed reply: reading the contract properly, signing the right pages, keeping both versions, and writing the reply that avoids a second round.
