Why this exists
What it does
Page thumbnails, bookmarks, search with the result highlighted on the page, zoom and fit controls, and full-screen reading.
Highlight, underline or strike out text, add sticky notes, free text, drawings, shapes, arrows and stamps such as APPROVED or DRAFT, in your choice of colours, with undo and redo.
Fill in a PDF’s form fields, place your own signature drawn or typed, and stamp your initials across every page of a forty-page contract in one action, which is also a single undo rather than forty.
Mark private text or an area and apply the blackout: the content underneath is permanently removed from the file, not painted over, and you are asked to confirm because it cannot be undone.
Drag to reorder pages, rotate or delete them, pull a selection into a new PDF or merge another one onto the end, then add Bates numbering, headers, footers, watermarks and Flatten to lock the fields you filled in, all drawn into the file itself.
Make searchable (OCR) reads a scanned page and adds real text beneath it, so search and highlighting work on a photocopied contract exactly like on any other PDF.
The honest part
The part you would otherwise find out in week three. If one of these is central to how you work, raise it before you buy rather than after.
