PowerPoint, Google Slides, LibreOffice Impress, and Apple Keynote all open ODP files with reasonable fidelity. Fonts, images, and standard transitions carry across. For presentations that must render identically to the original, export to PDF before sharing — PDF locks the layout against the recipient's environment.

Upload your ODP to KaijuConverter and pick PDF, PPTX, ODP, or image formats (one PNG per slide). Our LibreOffice Impress pipeline preserves slide layout, embedded fonts, images, and SmartArt. Animations and transitions flatten to static slides in PDF and image exports.
Animations and transitions are interactive effects; they only survive when converting between presentation formats that support them (PPTX ↔ ODP). Exporting to PDF or images produces a static snapshot of each slide at its final animation state. Use native ODP format if live playback is essential.
