How it works
Three steps.Nothing to learn.
- 1
Draw your signature
Click Draw in the inspector and sign with your trackpad or mouse. OneMacApp remembers it for next time.
- 2
Pick pages and placement
Click the pages to sign, then choose a position and size. Shift-click to select a run of pages.

Press Sign
A signed copy of each PDF lands in a dated OneMacApp folder in Downloads. The unsigned original stays as it was.
The details
Everything you’d want.Nothing you wouldn’t.
Draw once, reuse
Your signature is kept on your Mac as a clean transparent image, ready for the next document. Draw it again or clear it at any time.
Four placements
Put the signature at the bottom right, bottom center, bottom left or top right of the page.
Size it to fit
A slider sets the signature from 10% to 60% of the page width, so it sits neatly on a signature line.
Only the pages you choose
Sign the last page, every page, or just the ones with initials boxes. Several PDFs can be signed in one go.
