Frequently Asked Questions

ODP (OpenDocument Presentation) is an ISO-standardized open format used by LibreOffice Impress, OpenOffice Impress, and other compatible applications. It ensures long-term accessibility without proprietary lock-in.

No. All processing happens locally in your browser using JavaScript. Your files never leave your device, ensuring complete privacy for confidential presentations.

Text and basic formatting are preserved. PowerPoint animations, transitions, and slide timings are not converted. You'll need to recreate animations in LibreOffice Impress after conversion.

Font names, sizes, bold, italic, and colors are preserved. Microsoft-specific fonts (Calibri, Cambria) may be substituted with Liberation fonts in LibreOffice. Text positioning and alignment are maintained.

Embedded images (PNG, JPG, GIF) are extracted from PPTX and re-embedded in ODP format. Video and audio files are not transferred. Linked media must be re-embedded manually.

SmartArt graphics and complex PowerPoint shapes are simplified to basic text or shapes. For important diagrams, export them as images from PowerPoint and re-insert in LibreOffice.

ODP is an open standard ensuring long-term accessibility, free from vendor lock-in, and works with free software like LibreOffice. Ideal for archival, cross-platform collaboration, and avoiding subscription costs.

Tables with text are converted to ODP text frames. PowerPoint charts and data visualizations are simplified or lost. For complex charts, recreate them in LibreOffice Impress using its native charting tools.

ODP files are typically similar in size to PPTX, sometimes smaller due to efficient compression. Image-heavy presentations maintain similar file sizes.

Slide layouts may be simplified, custom PowerPoint themes are not preserved, animations are lost, and embedded fonts may be substituted. Always review the presentation in LibreOffice Impress and adjust formatting as needed.
