PPT is Microsoft's proprietary binary presentation format from the 1997-2003 era. ODP (OpenDocument Presentation) is the open ISO standard (ISO 26300) for presentations, used natively by LibreOffice Impress and Apache OpenOffice Impress. Converting PPT to ODP migrates a legacy proprietary presentation to the open standard, simultaneously modernizing the format and liberating it from vendor lock-in.

Government open-format mandates in multiple countries require ODP for official presentations. Organizations that receive legacy PPT files but must maintain them in open formats need this conversion for compliance. Converting PPT to ODP ensures these presentations remain accessible using free, open-source software without any Microsoft licensing dependency.

ODP conversion also future-proofs legacy PPT files. PPT is an aging binary format with declining support in newer software — each new version of LibreOffice or PowerPoint may render old PPT files slightly differently. Converting to ODP's well-documented XML standard ensures the content remains accessible and faithfully renderable far into the future.

LibreOffice parses the PPT binary using its PowerPoint import filter, reconstructing slides, text frames, drawing objects, animations, and embedded media from the OLE2 compound file. The presentation is then serialized as ODP: slides become <draw:page> elements, text frames become <draw:text-box>, shapes use ODF drawing primitives, and images are stored in the Pictures/ directory of the ZIP archive. PPT animations (entrance, emphasis, exit effects) are translated to ODP's SMIL-based animation model where equivalents exist. The output is ODF 1.2 compliant.

Simple animations (appear, fade, fly-in) typically transfer. Complex or custom animation sequences from PPT may simplify. Test in LibreOffice Impress to verify.

Yes. PowerPoint supports ODP import, though some animations and formatting may render slightly differently than in LibreOffice.

Sound effects attached to animations or slides in PPT may not transfer to ODP. Linked or embedded audio files are best verified after conversion.

ODP is an ISO standard with full public documentation. Unlike PPT (a proprietary binary), ODP's XML structure ensures any future software can read it accurately.

Standard clip art and AutoShapes are converted to ODF drawing primitives and render correctly in LibreOffice. Some very old WMF-based clip art may show minor visual differences.
