Highlight and add notes

Marking up a PDF is free, like on paper.

1. Open a PDF and press and hold on the text you want.
2. Choose Highlight and pick a colour.
3. To write on the page, open the edit tools and choose Text, then tap where it should go.

The edit tools also have Draw, Image and Move, so you can sketch, add a picture and move or resize any mark. Undo and Redo are always there.

Marks are saved into the PDF in the standard way, so they show up in other PDF apps too.
