What is ODP?
ODP (OpenDocument Presentation) is the slideshow format of the OpenDocument Format (ODF) family, an open standard maintained by OASIS. It stores slides, layouts, text, images, animations and transitions in a vendor-neutral XML-based file.
Like other ODF formats, an ODP file is a ZIP archive containing XML parts such as content.xml for the slides and styles.xml for formatting, plus embedded media. This open package can be read and written by any conforming presentation application.
How an ODP File Is Structured
An ODP follows the OpenDocument packaging model: a ZIP container holds a mimetype entry, content.xml for the slide structure, styles.xml for presentation styles and master pages, meta.xml, and a META-INF/manifest.xml that lists every part.[1] Drawing and presentation elements use the same XML vocabulary as ODF's drawing format, so slides, shapes, and frames are described declaratively.[1]
History and Standardization
OpenDocument was developed by the OASIS consortium from a format originating in OpenOffice.org, approved as an OASIS standard in 2005 and published by ISO/IEC as 26300 in 2006.[2] The specification has advanced through later revisions, with OpenDocument 1.3 published as an OASIS standard in 2021, adding features such as digital signatures and improved encryption.[3]
ODP vs PPTX
ODP and Microsoft's PPTX are both ZIP-and-XML presentation formats, but they use different, independently standardized XML schemas, so cross-application conversion can alter layout, animations, or embedded media.[2] ODP is implemented natively by suites such as LibreOffice and Apache OpenOffice and is favored where an open, vendor-neutral standard is a procurement or archival requirement.[1]

ODP vs Other Presentation Formats
| Feature | ODP | PPTX | |
|---|---|---|---|
| Type | OpenDocument presentation[1] | OOXML presentation | Fixed-layout document |
| Editable | Yes | Yes | Limited |
| Open/proprietary | Open standard[2] | Open, Microsoft-led | Open standard |
| Standardized by | OASIS & ISO/IEC[3] | ISO/IEC 29500 | ISO 32000 |
| Device/app support | LibreOffice, OpenOffice | Near-universal | Universal |
| Best for | Open-source workflows | Office collaboration | Final-form sharing |
ODP maximizes openness and tool independence, while PPTX offers wider out-of-the-box compatibility and PDF locks layout for viewing.
Advantages & Disadvantages
Advantages
ODP is a royalty-free ISO/IEC standard, letting presentations be opened and edited without reliance on a single proprietary application.
It is the native format of LibreOffice Impress and Apache OpenOffice Impress, and is also handled by Google Slides and PowerPoint.
The ZIP-and-XML packaging makes slide content accessible to standard tools for inspection, extraction or automated processing.
Its open specification reduces lock-in, helping organizations exchange presentations across different software ecosystems.
Disadvantages
Animations, transitions and complex layouts may render differently when an ODP file is opened in Microsoft PowerPoint.
PPTX dominates corporate settings, so recipients may not recognize ODP or have a suitable viewer installed.
Common Use Cases
ODP is used wherever an open, editable presentation format is preferred.
LibreOffice/OpenOffice slideshows | FileFormer
It is the default save format for Impress, covering lectures, business decks and project briefings.
Educational presentations | FileFormer
Schools and universities using free office suites distribute lesson slides in ODP.
Cross-platform sharing | FileFormer
Its open format eases presentation exchange between Linux, Windows and macOS office tools.

Can PowerPoint open ODP files?
Yes. Modern versions of Microsoft PowerPoint can open and save ODP files, although some animations, transitions or layouts may not transfer exactly between ODP and PowerPoint's PPTX format.
Is ODP the same as PPTX?
No. Both are ZIP-based XML presentation formats, but ODP follows the OASIS OpenDocument standard while PPTX follows Microsoft's Office Open XML standard. They are separate specifications.
What program opens ODP files?
LibreOffice Impress and Apache OpenOffice Impress open ODP natively. Google Slides and recent versions of Microsoft PowerPoint can also import and edit the format.
How do I convert ODP to PPTX or PDF?
Open the file in a compatible presentation app and use Save As or Export to choose PPTX or PDF. Online converters can also change ODP to other formats without installing software.
Is ODP an open standard?
Yes. ODP is part of the OpenDocument Format, an OASIS standard published as ISO/IEC 26300. The specification is royalty-free and not owned by any one vendor.
