Where these formats come from
Both of these formats are the same thing underneath: a zip archive full of XML files describing the text, the styles and the pictures. OpenDocument came first, from the OpenOffice project, and became ISO 26300 in 2006. Microsoft's Office Open XML followed and became ISO 29500 in 2008, after a standardisation fight so bitter that national bodies changed their votes under public argument. The outcome is that the world now has two open, documented, interchangeable office formats rather than one proprietary one — which is precisely why converting between them is possible at all, and why it mostly works.
Where you meet them
The conversion is needed whenever two people use different software on the same document: a colleague who works in LibreOffice sending a file to one who works in Microsoft Office, a public body that accepts only ODF, a client who insists on .docx. It also matters for the long term — an archive kept in an open format can still be opened in twenty years, whoever is still in business.
Questions people ask
Will my formatting survive the conversion?
Ordinary formatting — headings, bold, lists, tables, images, page breaks — comes through faithfully, because both formats describe the same things in much the same way. What travels badly is everything at the edges: complex nested tables, text boxes anchored to odd positions, uncommon numbering schemes, and anything built on a feature only one of the two has. Open the result and look at the places where you did something clever; that is where the differences will be, if anywhere.
What happens to my macros?
They do not come across. Macros are program code written for one particular office suite, and the other suite does not run that language — a Word VBA macro means nothing to LibreOffice Basic and the other way round. The conversion carries the document and discards the code. If a file's whole purpose is its automation, it has to be rewritten rather than converted, and that is a programming job rather than a file job.
Does the file lose quality?
It depends on what the two formats can hold. Converting between formats that store the same thing — a PNG to a BMP, a WAV to a FLAC — loses nothing. Converting into a format that throws information away to save space, such as JPEG or MP3, loses a little every time, and converting back does not bring it back. Where a choice exists, this page errs towards keeping the original quality rather than making the smallest file.
Is my file uploaded anywhere?
No. The conversion happens inside your browser, on your own machine; the file never leaves it and there is no server here that could receive it. That is why a large file is limited by your own memory rather than by an upload, and why nothing you convert can appear in anybody's logs — including ours. The audio and video tools do fetch their conversion engine from this site the first time you use them, some thirty megabytes once; after that the work still happens entirely on your machine.
Why people convert ODP to PPTX
An ODP file is a presentation made in LibreOffice Impress, Apache OpenOffice or another program of the OpenDocument family. A PPTX file is a PowerPoint presentation, and PowerPoint is still what most offices, conference organisers and clients expect. So the moment arrives when you have a deck in the first format and someone asks for the second. Perhaps a client opens everything in PowerPoint. Perhaps a conference sends its speakers a template and a rule. Perhaps a colleague with a different setup simply cannot read your file. The question is the same each time: how do I convert ODP to PPTX without rebuilding the deck from nothing?
This page does it in your browser. Your ODP is opened here, read slide by slide and written out as a PPTX that you can open in PowerPoint, edit and send on. Nothing is uploaded to a server, which matters when the deck holds figures that are not public, a client's name or material for an exam. Below you will find how it works, what comes through, what does not and how to check the result before you present from it.
One thing has to be said at the start, because it decides whether you will be pleased with the outcome. What comes out is a plainer deck than what went in. The slides, their order and the placement of text and pictures are carried across, but the decoration is not. If you expect an exact copy, you will be disappointed. If you expect a clean, editable skeleton that you finish in PowerPoint, you will be well served.
How the conversion works
Your deck is read and rewritten
An ODP is a package of files that describe slides in the language of OpenDocument. A PPTX is a package that describes slides in the language of PowerPoint. The two languages are related in spirit but not in detail, so a conversion has to read each slide, work out what it contains and write the same contents in the other language. Here, all of that happens in your browser. Your ODP is opened, every slide is read, and a PPTX file is written out for you to download.
Every slide keeps its boxes where they were
The conversion pays attention to position. A text box on the left of a slide stays on the left, a picture in the corner stays in the corner, and the boxes keep their sizes. This is what makes the result usable: when you open the PPTX, the slides look like skeletons of the originals, and you can see at once which text belongs to which slide.
The page size
The slide size is carried across as well. A widescreen deck stays widescreen, and a deck in the older four-to-three shape stays that way. You will not find the slides stretched or squeezed.
What is kept
Slides, order and page size
The slides are carried across in their original order, and the page size stays as it was. If your deck has thirty slides, the PPTX has thirty slides, in the same sequence.
Text boxes and pictures at their own positions
Every text box and every picture comes through at its own position and size. Pictures are embedded in the new file, so the PPTX is self-contained and can be moved without losing its images.
Bold, italic and bullet levels
Basic text formatting survives. Bold and italic are kept, and bullet lists keep their levels, so a point and its sub-points remain a point and its sub-points.
Tables
Tables are kept, with the caveat in the next section: they become plain rows of text, so the information is there, and the grid styling is not.
What is not carried over
A drawing language of its own
Fonts, colours, backgrounds, gradients, shadows, charts, animations, transitions, speaker notes and master slides are not carried over. These are not small details. Each of them is a drawing language of its own, with rules that differ between the two formats, and a half-finished translation would look converted while being wrong. It is better for the result to be honestly plain than to look right and break when you open it.
What this means in practice
Expect the PPTX to use the default look of PowerPoint. The font you chose in Impress, the gradient behind the title and the shadow under the pictures will be gone. Charts will not be there as charts, and the animations that bring in your bullet points one by one will not play. Speaker notes will not appear in the notes pane. Master slides, the templates that give a deck its consistent look, are not transferred, so you will need to apply a theme of your own in PowerPoint.
Tables become plain rows
Tables are turned into plain rows of text. The content is preserved, but borders, shading and merged cells are not. If a table is central to a slide, plan to rebuild its formatting after you convert ODP to PPTX.
Check before you present
Open the result and check it before you present from it. Go through the slides one by one, look for the places where something you rely on has gone and fix them while you still have time. This is sound advice for any conversion between office formats, and it separates a smooth presentation from an awkward one.
How to convert ODP to PPTX here
Add your deck
Drop the ODP onto the page or pick it from your device. It is opened inside your browser and is not uploaded.
Convert
Press the button. A deck of moderate size takes a few seconds, and a long one with many pictures takes longer. Leave the page open until it finishes.
Download and open
Download the PPTX and open it in PowerPoint, or in any program that reads the format. Go through the slides, apply a theme and correct whatever needs correcting.
A closer look at ODP and PPTX
Two standards for the same job
ODP belongs to OpenDocument, which was developed in the open and standardised as an alternative to the formats of the large office suites. PPTX belongs to the Office Open XML family, defined by Microsoft and later standardised. Both are, at heart, packages of XML files and media. That is why a conversion is possible at all, and also why it is never perfect: the two formats describe the same ideas with different structures and a different vocabulary.
Why PPTX is still asked for
Even if you prefer free software, the world around you runs on PowerPoint. Clients send decks in it, conference computers are set up for it and teachers receive homework in it. A PPTX is the format that is least likely to cause a question. That is a fair reason to convert ODP to PPTX even when you would rather not.
The role of the theme
In PowerPoint, the look of a deck lives in the slide master and the theme. Because the masters are not transferred, the cleanest workflow is to choose a theme in PowerPoint after you convert, and let the plain slides take on its look. A few minutes of work restores consistency.
Common situations in detail
Sending a deck to a client who uses PowerPoint
You built a presentation in LibreOffice and a client wants to open it in PowerPoint. Convert ODP to PPTX, restyle it with a theme, check the slides and send it. Send a PDF as well if the exact look matters, as it will be the same on every screen.
Conference and event requirements
Conference organisers often ask for PPTX files because their computers are set up for them. If you prepared your talk in an open-source program, convert it a day before and test it. Bring the PDF as a fallback.
Schools and universities
A student working on LibreOffice may be asked to hand in a PPTX. The conversion gives the teacher a file that opens without trouble. Since the formatting is plain, add a theme so that the slides look deliberate.
Moving old decks into a new environment
An organisation that used an open-source suite and is now moving to Microsoft 365 may have years of ODP files. Converting them preserves the content: the text, the pictures and the structure. The design will need to be re-applied, but the hard work of writing the slides is saved.
Questions people ask before converting
Will it look identical to my original deck?
No. The positions and the content are kept, but fonts, colours, backgrounds, effects, charts and animations are not. Expect a plainer deck.
Will my animations and transitions work?
No. They are not carried over. Add new ones in PowerPoint.
Are my speaker notes kept?
No. Speaker notes are not carried over, so copy them out of the original if you need them.
Is my deck uploaded?
No. The conversion runs in your browser and the deck never leaves your device.
Can I convert the PPTX back to ODP?
Yes. PPTX to ODP works in the other direction, and the same limits apply. A round trip makes the deck plainer still, so always work from your original.
Choosing wisely when you convert ODP to PPTX
Decide what you need from the result
Before you convert ODP to PPTX, ask what the new file is for. If it is for presenting, plan to restyle it. If it is for sending content to someone who will edit it, the plain version may be quite enough. Knowing the purpose tells you how much work lies ahead.
Simplify the source first
A deck made of simple slides with text boxes and pictures converts cleanly. A deck full of grouped shapes and layered effects converts into something much plainer. If you can, simplify the ODP a little before you convert ODP to PPTX, and expect to rebuild the complicated slides.
Keep the original
The ODP is the master. Keep it, because it holds everything the PPTX lost. If you later need the full design, the animations or the notes, you will find them only in the original.
Test with a few slides first
If your deck is long and important, convert a short version with a few typical slides first. See how PowerPoint treats them. If the result is acceptable, convert the whole deck with confidence.
Getting a good result after the conversion
Start with a theme
Open the PPTX in PowerPoint, choose a theme and apply it. Because the converted slides carry no master of their own, they take on the theme cleanly, and you can restore a consistent look in a few minutes.
Fix the fonts once
Select all the text and set the font you want in a single step. When you convert ODP to PPTX, the fonts of the original are not transferred, so this one action replaces a long chain of manual corrections.
Rebuild charts from their data
A chart is not carried across as a chart. Open the original, copy its figures and create a new chart in PowerPoint. For a few charts this takes minutes, and the new ones will be editable.
Re-add animations sparingly
Animations and transitions are gone. Think about whether you really need them. Add a few where they help, and leave the rest.
Privacy and handling
Why local conversion matters for presentations
Presentations often hold what an organisation would rather keep inside: figures, plans, names of clients, drafts. Many online converters ask you to upload the deck to a server, process it and return it, and for a time a copy lives on a machine that you do not control. Here your own browser does the work, so the deck stays on your device.
What happens when you leave
When you close the page, the converted file disappears from the browser, so download it first. Nothing about your deck is kept.
If something goes wrong
The PPTX opens with missing pictures or text
Compare it with the original. Some objects, such as charts or grouped shapes, are not carried over. Re-insert them in PowerPoint.
The slides look different from the original
That is expected. Fonts, colours and backgrounds are not transferred, so PowerPoint applies its own defaults. Apply a theme to restore a consistent look.
The conversion fails on a very large deck
Everything happens on your device, so a deck with hundreds of large pictures may be too heavy for a phone. Try again on a computer, or split the deck into two parts.
Related presentation and document tools
The same family of tools covers the other common jobs. To go the opposite way, use PPTX to ODP. If you need a file that looks the same everywhere, ODP to PDF and PPTX to PDF turn a deck into a PDF. A PDF can be turned into editable slides again with PDF to PPTX or PDF to ODP. For text documents, ODT to DOCX and DOCX to ODT do for letters and reports what this page does for slides, and ODS to XLS does the same for spreadsheets.
A worked example
Say you have prepared a talk of twenty slides in LibreOffice Impress, and the conference you are visiting asks for a PPTX. You drop the ODP here and press the button. A few seconds later you download a PPTX with twenty slides, each with its text and pictures in place. The colours are gone and the title font is PowerPoint's default, so you apply a theme, rebuild one chart and save. The ODP stays in your folder in case you ever need the exact design, and you take a PDF along as a precaution.
A short checklist
Before converting
Know what the PPTX is for. Keep the ODP safe. Decide whether you will restyle the deck.
While converting
Stay on the page until the file is ready.
After converting
Open the PPTX, go through every slide, apply a theme and correct tables, charts and anything else that did not come across.
Common mistakes
Expecting an exact copy
Do not convert ODP to PPTX expecting the same fonts, colours and effects. They are not carried over.
Presenting without checking
Always open the result and go through it before you present from it.
Discarding the original
Keep the ODP. It holds the design, the notes and the animations.
Your deck stays on your device
The conversion happens locally. Your deck is read by your own browser, rewritten there and handed back. Nothing is uploaded, so no copy ends up on a server and nobody else can read it. For presentations with sensitive content, that is the safe way to convert ODP to PPTX.
Summary
To convert ODP to PPTX here, drop the deck and press the button. Your ODP is opened in your browser and written out as PPTX. Every slide keeps its boxes where they were, and the slides, their order, the page size, text boxes and pictures at their own positions, bold and italic, bullet levels and tables come across. What comes out is a plainer deck than what went in: fonts, colours, backgrounds, gradients, shadows, charts, animations, transitions, speaker notes and master slides are not carried over, and tables become plain rows of text. Open the result and check it before you present from it. Nothing leaves your device.
