Price

LibreOffice is free to download from libreoffice.org, and the Mac App Store version costs $8.99 once. Deck costs $19 once, tax included, and includes every future update for up to 3 of your Macs. It is free for 7 days with no card, and refunds are available within 30 days.

Native file format

By default LibreOffice loads and saves files in the OpenDocument format, and Impress saves in a Microsoft Office format through File > Save As. Deck’s native file format is .pptx, so it opens and saves PowerPoint files directly. A deck saved by Deck keeps its slides, layouts, placeholders, bullets, pictures, tables, notes, theme and transitions.
