Its annotation tools include sticky notes, measuring tools, shapes, strikethrough, underline, highlighting, and custom stamps for document review and status marking. Interactive PDF forms can be created or edited with buttons, text fields, checkboxes, event handlers, automatic calculations, data validation, and JavaScript support.
