PPTX to ODP
For LibreOffice Impress and the open standard — slides, notes and pictures kept.

How to convert PPTX to ODP
- Drop the file.
- Nothing to choose.
- Press Convert and download.
What happens to your file
LibreOffice opens the file headless on Fylane’s servers and writes the target with its own export filter — the same conversion Save As does on a desktop, without the desktop. Deleted on schedule.
Transitions and animations are the part most often lost between the two formats; text, layouts, pictures and notes carry over.
Questions
Do animations and transitions survive?
Some, not all. The two formats describe motion differently, so a simple fade or wipe usually maps across and anything elaborate does not. Check any slide that leans on its animation before you present from it.
Can Impress open a PowerPoint file without converting?
Yes — LibreOffice Impress reads .pptx directly. Convert when you want the deck genuinely stored as OpenDocument, which is usually a standards or archiving requirement rather than a practical one.
What comes through cleanly?
Text, slide layouts, images, tables, charts and the speaker notes. Notes are the ones people forget to check and they do carry over.
Why do my fonts look different?
Because the font is named in the file rather than embedded in it, so the machine opening the deck substitutes whatever it has. Sticking to widely installed families, or exporting to PDF for presenting, avoids the surprise.
What is ODP?
OpenDocument Presentation, the presentation half of the same open ISO standard that gives ODT for text and ODS for spreadsheets. It is what LibreOffice Impress and OpenOffice use natively.
How do I go the other way?
The ODP to PPTX page converts an OpenDocument deck into PowerPoint format.
Do it once, not on every form
Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
