When to use it
When reviewing contracts, marking up drafts, commenting on designs or studying: highlight key points, underline, strike out what should go and leave notes right beside it.
Tips
Drag across a line of text to highlight exactly those words; use Notes for longer comments and the pen to circle areas. Every annotation can be recolored, moved or deleted.
Good to know
Annotations are saved as standard PDF annotations, so they show up in Adobe Reader, browsers and phones. Everything runs in your browser; your file is never uploaded.
