ODP Format: The Complete Guide to OpenDocument Presentations

PC By Pablo Cirre • Updated May 7, 2026

What Is ODP?

ODP stands for OpenDocument Presentation, the presentation file format defined by the OASIS OpenDocument standard, ISO/IEC 26300. It is the native format of LibreOffice Impress and Apache OpenOffice Impress, the open-source counterparts to Microsoft PowerPoint. Like PPTX, ODP is a ZIP archive containing XML files. Unlike PPTX, which was designed primarily by Microsoft, ODP was designed by an industry consortium prioritising vendor neutrality and long-term archivability.

ODP shares structural DNA with the other OpenDocument formats: ODS (spreadsheets) and ODT (word processing). All three use the same content.xml + styles.xml + meta.xml + settings.xml + META-INF/manifest.xml pattern inside a ZIP container, with format-specific presentation elements added in content.xml.

ZIP Container Structure

mimetype                         — Uncompressed; declares application/vnd.oasis.opendocument.presentation
META-INF/
  manifest.xml                   — All files listed with MIME types
content.xml                      — All slides, master pages, styles (main document)
styles.xml                       — Drawing styles, page layout styles
meta.xml                         — Author, creation date, word count, slide count
settings.xml                     — View settings (current slide, zoom, grid)
Thumbnails/
  thumbnail.png                  — Preview image (128×128)
Pictures/                        — Embedded raster images
Object1/                         — Embedded OLE objects (charts, spreadsheets)
  content.xml

The mimetype file must be the first entry in the ZIP archive, stored uncompressed — the same requirement as other OpenDocument formats, enabling MIME sniffing without decompression.

content.xml: Slides and Drawing Layers

The content.xml file uses the drawing (dr3d, draw) and presentation (presentation) XML vocabularies to describe slides:

<office:presentation>
  <!-- Master page (template for all slides) -->
  <draw:master-page draw:name="Zen" draw:style-name="dp1">
    <draw:frame presentation:class="title" ...>
      <draw:text-box><text:p/></draw:text-box>
    </draw:frame>
  </draw:master-page>

  <!-- Actual slide -->
  <draw:page draw:name="slide1" draw:master-page-name="Zen"
             draw:style-name="dp2" presentation:presentation-page-layout-name="AL1T0">
    <!-- Title shape -->
    <draw:frame presentation:class="title" svg:x="1cm" svg:y="0.5cm"
                svg:width="25cm" svg:height="3cm">
      <draw:text-box>
        <text:p><text:span text:style-name="T1">My Presentation</text:span></text:p>
      </draw:text-box>
    </draw:frame>

    <!-- Content shape -->
    <draw:frame presentation:class="body" svg:x="1cm" svg:y="4cm"
                svg:width="25cm" svg:height="13cm">
      <draw:text-box>
        <text:list>
          <text:list-item><text:p>First bullet</text:p></text:list-item>
          <text:list-item><text:p>Second bullet</text:p></text:list-item>
        </text:list>
      </draw:text-box>
    </draw:frame>

    <!-- Slide transition -->
    <presentation:notes>
      <draw:text-box><text:p>Speaker notes here</text:p></draw:text-box>
    </presentation:notes>
  </draw:page>
</office:presentation>

Positioning: Absolute Coordinates

A fundamental difference from PPTX: ODP positions shapes using absolute SVG coordinates (svg:x, svg:y, svg:width, svg:height) in centimetres or millimetres. PPTX uses EMU (English Metric Units, 914400 per inch). This makes ODP XML more human-readable but means that changing the slide size requires manually adjusting all shape positions.

Styles Architecture

ODP separates styles across two files:

content.xml — automatic styles (generated by the application, named P1, P2, etc.) used for specific text runs
styles.xml — named styles (paragraph styles, drawing styles, page styles) intended for reuse

Drawing styles for shapes include fill, stroke, shadow, opacity, and text animation. The style system is similar to CSS in its cascade and inheritance model.

Animations in ODP

ODP uses the SMIL (Synchronized Multimedia Integration Language) vocabulary for animations, specifically the subset defined in the OpenDocument presentation animations specification:

<presentation:show-shape draw:shape="id3">
  <presentation:show-text/>
</presentation:show-shape>

<anim:par>
  <anim:seq presentation:node-type="main-sequence">
    <anim:par>
      <anim:animate attributeName="opacity" from="0" to="1"
                    dur="PT0.5S" fill="hold"
                    xlink:href="#id3"/>
    </anim:par>
  </anim:seq>
</anim:par>

The SMIL-based approach differs significantly from PPTX's <p:timing> XML. When converting between formats, LibreOffice translates animations as best it can, but complex sequences — particularly motion path animations, morph transitions, and text-by-character effects — may not survive the round trip.

Slide Transitions

Transitions are defined per slide using presentation:transition-style and presentation:transition-speed attributes in the <draw:page> element, optionally combined with <presentation:sound> elements for audio:

<draw:page draw:name="slide2"
           presentation:transition-type="automatic"
           presentation:transition-style="fade-smoothly"
           presentation:transition-speed="medium"
           presentation:duration="PT3S">

Supported transition types in LibreOffice Impress include fade, push, wipe, box, checkerboard, and many others. Not all of these map directly to PowerPoint transition equivalents.

Master Pages vs. Slide Masters

ODP uses the concept of master pages (analogous to PowerPoint's slide masters) stored inline in content.xml. Unlike PPTX, which separates master and layout into distinct files with an explicit hierarchy, ODP's master page combines the equivalent of master + layout in a single entity. This simplifies the structure but makes multi-layout systems less explicit.

A presentation can reference multiple master pages, allowing different "themes" for different sections — but the inheritance chain is less granular than PPTX's three-tier system.

Macro Support

ODP supports macros through LibreOffice's scripting framework:

LibreOffice Basic — the primary macro language
Python — available via the BASIC bridge in LibreOffice 6.4+
JavaScript — experimental

Macros are stored in the ZIP archive under Basic/Standard/ModuleN.xml. Unlike PPTM, there is no separate "ODP with macros" extension — any ODP file may contain macros.

ODP vs. PPTX: Compatibility Matrix

Morph/Zoom transitions	✅	❌	Office 365 only
SmartArt	✅	❌	Converted to plain shapes
Embedded charts	✅	✅	ODS chart data vs. XLSX
Speaker notes	✅	✅	Full compatibility
Master page themes	✅	Partial	Less granular in ODP
VBA macros	✅ (PPTM)	❌	LibreOffice Basic instead
Font embedding	✅	Partial	Limited in LibreOffice

Interoperability: Round-Trip Conversion

ODP → PPTX (LibreOffice → PowerPoint): Opening an ODP file in PowerPoint or converting via LibreOffice's "Save as PPTX" works for basic presentations. Known loss areas:

Custom animation sequences may simplify or reorder
Slide transitions may change type
Complex master page configurations may flatten
LibreOffice Basic macros are dropped

PPTX → ODP (PowerPoint → LibreOffice):

SmartArt is converted to a static group of shapes (non-editable SmartArt structure)
Morph and Zoom transitions become simple cuts or fades
Charts retain data but switch to ODS format internally
VBA macros are dropped
Most text formatting, images, and basic transitions survive

Google Slides and ODP

Google Slides can import ODP files via Google Drive upload. The conversion preserves:

Basic slide content (text, images)
Simple transitions
Speaker notes

It does not preserve:

Custom animations (converted to simple appear/disappear)
LibreOffice-specific drawing effects
Macros

Exporting from Google Slides to ODP is also available (File → Download → ODP), providing a path from Google's cloud to an open-standard format.

When to Use ODP

Use ODP when:

Working primarily in LibreOffice Impress
Submitting to organisations requiring open-standard file formats
Creating presentations that will be archived long-term without vendor dependency
Collaborating with users committed to open-source toolchains

Use PPTX when:

Collaborating with PowerPoint users (corporate standard)
Using advanced PowerPoint features: SmartArt, Morph transitions, complex animations, embedded Excel charts
Distributing to audiences who will present with PowerPoint

Converting ODP Files

ODP → PPTX: File → Save A Copy → PowerPoint 2007-365 (.pptx) in LibreOffice Impress. Most basic content survives.

ODP → PDF: File → Export as PDF. All visual content is preserved; animations and transitions are rendered as static slides. Fine-grained PDF options include PDF/A compliance for archival.

ODP → PNG/JPG: File → Export → select image format. Exports each slide as an image.

PPTX → ODP: File → Save As → ODP in LibreOffice Impress. VBA macros, SmartArt, and Morph transitions are not preserved.

Summary

ODP is the OpenDocument standard's answer to PPTX — a mature, ISO-standardised presentation format built for vendor independence and long-term compatibility with open-source tools. While it lacks some of PowerPoint's flagship features (Morph transitions, SmartArt, advanced animation sequences), ODP handles the fundamentals — slides, text, images, basic animations, speaker notes, and embedded charts — with full competence. For presentations that must remain free from commercial software lock-in, ODP is the natural choice.

On KaijuConverter every file is processed inside an isolated container, encrypted in transit (TLS 1.3) and at rest, and automatically deleted after 60 minutes with multi-pass overwrite. We never train on, share, or analyze user content. For maximum privacy on extremely sensitive material, prefer offline tools (ImageMagick, FFmpeg, LibreOffice) that you control end-to-end.

LibreOffice Basic macros are dropped entirely. Complex animation sequences may simplify or reorder. Some slide transitions change type. Custom drawing effects may not render identically. Basic content — text, images, simple transitions, speaker notes, and charts — generally survives the conversion.

For 95% of use cases, yes — server-side ImageMagick, FFmpeg and LibreOffice produce identical output to the same tools on your laptop. Desktop software wins for: extremely large files (multi-GB), batch jobs of thousands of files, scripted pipelines, or content too sensitive to upload. KaijuConverter caps at 25 MB per file on the free tier (up to 2 GB on paid plans).

Most format conversions are lossy by design — JPG, MP3, MP4, WebP all discard perceptual data to save bytes. Going through a lossy intermediate compounds the loss. To minimize visible/audible drift: convert from the original master, choose a higher quality setting, and avoid converting back and forth between lossy formats.

Both are ZIP+XML formats, but ODP is governed by OASIS/ISO and used in LibreOffice, while PPTX is governed by ECMA/ISO and designed by Microsoft. PPTX has richer features (SmartArt, Morph transitions, VBA macros, three-tier master/layout/slide hierarchy). ODP is preferred for open-source workflows and open-standards mandates.
