Questions
Can I sign without leaving Mail?
The share extension can prepare the document and offers a quick-sign flow when a saved signature and Pro access are available. The full editor opens in PDF Sign for deliberate placement and review.
Does the original attachment change?
No. The app creates a signed export that you share as a separate copy.
