The short answer
- ODP is an editable presentation format that stores a sequence of slides in an OpenDocument package, with some PowerPoint features changing or being lost during interchange.
- Open an ODP file with LibreOffice Impress, Apache OpenOffice Impress, or a supported desktop edition of Microsoft PowerPoint. PowerPoint 2016, 2019, 2021, 2024, and Microsoft 365 can open and save ODP files. After opening, inspect slide layouts, fonts, themes, transitions, animation, audio, and video because application support differs.
- Treat an unfamiliar ODP as potentially active content rather than a collection of static slide images. ODF structures can include scripts, event listeners, macro execution, external references, embedded media, subdocuments, and encrypted parts. Use maintained software, disable or decline active content, restrict external-resource access, and preview untrusted files in an isolated environment.
ODP File: How to Open, Inspect, and Convert OpenDocument Presentations
An ODP file is an OpenDocument Presentation standardized by OASIS and corresponding to ISO/IEC 26300. A typical file is a ZIP-based package containing XML parts such as content.xml, styles.xml, and meta.xml, plus META-INF/manifest.xml. In ODF 1.3, the presentation body contains office:presentation.
Keep the original file before conversion. When converting ODP to PPTX or PPTX to ODP, verify every slide: themes, layouts, animation, transitions, sound, ActiveX controls, and advanced effects may change or disappear. Microsoft recommends saving the PowerPoint version first and then saving a separate ODP copy.
How to open it

PowerPoint 2016, 2019, 2021, 2024, and Microsoft 365 can open and save ODP files.

File safety
Treat an unfamiliar ODP as potentially active content rather than a collection of static slide images. ODF structures can include scripts, event listeners, macro execution, external references, embedded media, subdocuments, and encrypted parts. Use maintained software, disable or decline active content, restrict external-resource access, and preview untrusted files in an isolated environment.
An unknown sender, a name ending in two extensions, or contents that do not match the extension — check before you open it.
Converting it

Convert a copy, never the original, then compare quality, metadata, and layout against what you started with.
Common questions
What is an ODP file format and what is it used for?
ODP is the editable presentation member of the OpenDocument family. It represents a presentation as a sequence of slides and is standardized by OASIS, corresponding to ISO/IEC 26300.
How do I open an ODP presentation file?
Use LibreOffice Impress, Apache OpenOffice Impress, or Microsoft PowerPoint 2016, 2019, 2021, 2024, or Microsoft 365. Check layouts, animation, transitions, and media after opening because feature support can differ.
How do I open an ODP file on Windows?
In Windows, open the file from LibreOffice Impress, Apache OpenOffice Impress, or a supported PowerPoint version. If Windows asks for an app, choose one of these presentation applications and review the slides after import.
How do I open an ODP file on Mac?
On a Mac, use LibreOffice Impress or a supported Microsoft 365 PowerPoint installation. Inspect formatting and effects after opening because ODP and PowerPoint features do not always map exactly.
How do I open an ODP file on a phone?
Mobile support varies by app—use a maintained presentation app only if it explicitly lists ODP support. If it cannot open the file, open it in desktop Impress or a supported PowerPoint version.
Why will my ODP file not open or appear invalid?
Confirm the extension and MIME type application/vnd.oasis.opendocument.presentation. A packaged ODP should contain META-INF/manifest.xml and an uncompressed first-entry mimetype file with the presentation MIME value; missing or damaged package parts can prevent parsing.
Should I use ODP or PPTX for a PowerPoint presentation?
Use ODP for an OpenDocument presentation workflow and keep PPTX when PowerPoint-specific fidelity matters. Moving between them may alter themes, layouts, animation, transitions, sound, ActiveX controls, or advanced effects.
How can I convert ODP to PPTX without losing presentation effects?
No lossless result is guaranteed. Preserve the original ODP, convert a separate copy in a compatible presentation application, and inspect every slide, animation, transition, sound, theme, layout, and embedded object.
Are ODP presentation files safe to open?
Not automatically. ODP packages can contain script or event structures, external references, embedded media, subdocuments, and encrypted parts. Use maintained software, reject unexpected active content, restrict external access, and isolate unfamiliar files.
What are the ODP MIME type, ZIP structure, and file signature?
The MIME type is application/vnd.oasis.opendocument.presentation. A typical ODP is a ZIP package with META-INF/manifest.xml and XML parts; its mimetype file must be the first uncompressed ZIP entry without extra fields, enabling fixed-position identification.
