ODP to PPTX Converter
Turn an OpenDocument presentation into an editable PowerPoint .pptx file, with speaker notes and the hidden or visible state of each slide carried across. Because LibreOffice does the rewriting rather than PowerPoint, open the result once and check animations and fonts before you present.

ODP, PPTX, and what actually changes
ODP is the OpenDocument Presentation format that LibreOffice Impress and Apache OpenOffice save by default. PPTX is the Office Open XML presentation format Microsoft PowerPoint has used since Office 2007, and it is what most recipients, school submission portals and shared-drive templates expect. ODP support in Office varies by version and platform, so sending a .odp often means an email back asking for a PowerPoint file instead.
On our servers the file goes through the LibreOffice 7.4 command line in headless mode, using the Impress MS PowerPoint 2007 XML export filter. That means your slides are re-written as OOXML parts, not photographed: shapes stay shapes, text boxes stay editable text, and the deck opens in PowerPoint as a working presentation rather than a stack of pictures. Nothing is rendered to images along the way.
In our test deck, speaker notes survived the conversion and a hidden slide stayed hidden in the PPTX, flagged rather than deleted. Text, bullet lists, shapes and placed images come across as Impress represents them internally. Expect anything Impress and PowerPoint model differently, such as some animations, slide transitions and multimedia effects, to be simplified or dropped, so step through the deck once before a live presentation.
This is the tool for people who build decks in Impress on Linux but have to hand in a PowerPoint file, for anyone working with colleagues who edit in Office or Google Slides, and for recovering an old OpenOffice presentation into a format today's apps prefer. If the recipient only needs to read the deck, ODP to PDF is the more faithful route: that path uses LibreOffice 25.8 in a container with a full font set and embeds the fonts it uses.
How to convert ODP to PPTX
- Open the deck in Impress one last time and tidy anything you care about: unhide slides you want visible, confirm your notes are in the notes pane, and replace rare display fonts with widely installed ones if the file will be opened on another machine.
- Drag the .odp file onto this page. Without an account you can send up to 10 files per request at up to 50 MB each; a free account raises the per-file limit to 100 MB.
- Check that the target is set to PPTX, then start the conversion. The file is uploaded over HTTPS and converted by a worker on our server, not in your browser.
- Wait for the job to finish. Decks this size usually take only a few seconds once the upload completes.
- Download the .pptx within about four hours of finishing, then open it in PowerPoint, Google Slides or Keynote and step through the slides, the slide master and any animations.
What this converter does
- Rewrites the OpenDocument XML into a real OOXML package with the LibreOffice Impress PowerPoint 2007 filter, so every slide stays editable
- Carries speaker notes into the PPTX notes pane, verified on our test deck
- Keeps slides you marked hidden flagged as hidden instead of silently deleting or revealing them
- Outputs modern .pptx (Office 2007 and later), which PowerPoint, Google Slides, Keynote and LibreOffice can all open
- Detects password-protected ODF presentations and tells you to remove the password rather than failing with a vague error
- Up to 10 files in one request on the free tiers, with ODP to PDF available from the same page if you need a read-only copy

ODP to PPTX questions
Is the converted file fully editable?
Yes. The output is a standard .pptx package, so you can edit text, move shapes and change the design in PowerPoint, upload it to Google Drive and open it with Google Slides, or edit it in Keynote and LibreOffice Impress.
Do my speaker notes come across?
Yes. In our test conversion the notes attached to each slide appeared in the PowerPoint notes pane. Notes are the one thing that gets lost if you convert the deck to PDF instead, so use PPTX when you still need them.
What happens to animations and slide transitions?
Impress and PowerPoint do not describe effects the same way, so some animations and transitions can be simplified or dropped by the export filter. Static content is reliable; treat effects as something to review and, if needed, reapply in PowerPoint.
Will the slides look identical, with the same fonts?
Layout and content transfer, but fonts are not travelling inside the file as font files. If your deck uses a typeface that is not installed on the opening machine, PowerPoint substitutes a different one and line breaks can shift. Sticking to common fonts, or sending a PDF alongside, avoids that.
Can I convert ODP to the old .ppt format?
Not directly from this page: ODP converts to PPTX or PDF. If someone needs legacy .ppt, convert the deck to PPTX here first, then run the PPTX through our PPTX to PPT converter.
Can I turn a PDF, PPSX or Keynote file into PPTX here?
No. This page accepts .odp files. We also do not accept .pps or .ppsx uploads at all, so a PowerPoint slideshow file has to be re-saved as .ppt or .pptx in PowerPoint before it can be converted; .ppt converts to .pptx here.
Is there a batch mode for a folder of presentations?
You can send up to 10 files in one request on the guest and free tiers, 25 on Plus and 50 on Pro, and each request counts as one job against an hourly limit of 10 jobs for guest and free users. There is no single ZIP download for a batch, so you pick up the converted decks one at a time.
What happens to my file after conversion?
The conversion runs on our servers, not in your browser. Your uploaded .odp is deleted as soon as the job finishes, and the converted .pptx stays downloadable for about four hours through a random, unguessable link before it is deleted automatically. File names, sizes and outcomes are logged, and signed-in accounts keep a conversion history row.
