PDF to Keynote converts PDF-based presentations (e.g., made using LaTeX and Prosper) into Apple's Keynote format. Presenting in Keynote has several advantages over Preview or Adobe Reader, including a highly configurable presenter display, rehearsal support, notes and annotations visible only to the presenter, and of course Keynote's trademark transitions. Once translated into Keynote format, every page of your original PDF file becomes a PDF image, properly scaled and centered on its own slide. Although intended for presentations, you can also use it to create slides for the pages of regular documents. A preference lets you choose which version of the Keynote XML file format to produce. PDF to Keynote is free.
