ODP file format
ODP is the presentation format of LibreOffice Impress and the OpenDocument standard — the open-source counterpart to PPTX, and a PDF export away from universal sharing.

What is ODP?
ODP completes the OpenDocument trio alongside ODT and ODS, standardised by OASIS in 2005. A file is a ZIP archive containing `content.xml` with the slide structure, style definitions and a media folder holding every image and video placed on a slide — the same architecture as PPTX, under a different specification.
LibreOffice Impress and Apache OpenOffice treat it as native, and Google Slides imports it. PowerPoint can open ODP as well, but this is the weakest of the three OpenDocument conversions: slide masters, animations, transitions and SmartArt-style diagrams frequently need manual repair after crossing between the two suites.
That makes PDF the sensible delivery format for an ODP deck heading to an unknown recipient. It preserves layout, fonts and slide order exactly, needs no office suite at all, and sidesteps the entire question of whose presentation software will render your master slides correctly.

ODP: frequently asked questions
- What opens an ODP file?
- LibreOffice Impress and Apache OpenOffice open it natively. Google Slides imports it, and PowerPoint can open it too, though with more layout drift than the other OpenDocument formats. Any of these will let you read and edit the deck.
- Does PowerPoint open ODP?
- Yes, but expect the roughest ride of the OpenDocument family. Text and images arrive intact; slide masters, animations, transitions and diagram objects are the parts that commonly need fixing by hand after the import.
- ODP or PPTX — which should I use?
- PPTX if the deck will be edited or presented by PowerPoint users, ODP if you work in LibreOffice Impress and control the whole chain. When the audience is unknown, export to PDF and avoid the compatibility question entirely.
- Do animations survive conversion to PPTX?
- Basic ones sometimes do, elaborate ones usually do not. The two suites model animation timelines differently, so effects can lose their timing, their order or disappear altogether. Rebuild critical animations in the target application rather than trusting the import.
- Why do fonts change when I open an ODP elsewhere?
- Because the file references fonts by name instead of embedding them. A machine without your typeface substitutes another, shifting text boxes and sometimes pushing lines off the slide. Exporting to PDF locks the fonts in place permanently.
- How do I share an ODP with someone who has no LibreOffice?
- Export to PDF. It opens in any browser, on any phone, with the layout exactly as you designed it, and it needs no office software. Send the ODP itself only when the other person genuinely has to edit the slides.
