What opens an ODP file?
An ODP file opens in LibreOffice Impress and Apache OpenOffice Impress (its native programs), in Microsoft PowerPoint, in Google Slides by import, and in browser tools such as Publish Media Software (PublishMedia). PublishMedia needs no install and is free to view, showing every slide as a page. Editing and PDF export need a paid plan.
Why open .odp presentations in PublishMedia?
If someone sent you slides made in LibreOffice and you don't have it, these are the practical reasons to open them here.
No PowerPoint, no problem
You don't need PowerPoint, LibreOffice or a Google account. Any modern browser on Windows, Mac, Chromebook, Linux or iPad opens the .odp.
Slides keep their LibreOffice look
Each slide opens laid out as LibreOffice Impress shows it, instead of being rebuilt in another program's slide format.
Drawings open too
An .odg flyer, map or diagram from LibreOffice Draw opens as a page in the same editor as your slides.
Turn slides into handouts
On a paid plan, tidy the slides, add pages and export a print-ready PDF for a meeting, a class or a church service.
Know what changed
The Import Report lists anything worth reviewing, such as a font that was swapped, so nothing slips past you before you print or share.

7 ways to open ODP and ODG files in 2026
Presentations and drawings from LibreOffice open in more places than people expect. Here is what each option does well, and where it falls short.
- 1
Publish Media Software
Browser-based (Windows, Mac, Chromebook, Linux, iPad)✓ Opens .odtFree to openOpens .odp slides and .odg drawings as pages laid out as LibreOffice shows them, with no install. Looking through slides costs nothing, editing and PDF export come with a paid plan, and it is a page editor rather than a tool for presenting a live slideshow.
Open your .odp file free - 2
LibreOffice Impress
Desktop (Windows / Mac / Linux)✓ Opens .odtFree (open source)The native program for .odp, with full editing and slideshow mode. You must install the whole LibreOffice suite to use it.
- 3
LibreOffice Draw
Desktop (Windows / Mac / Linux)✓ Opens .odtFree (open source)The native program for .odg drawings, and it comes in the same LibreOffice download. It is the most faithful choice for diagrams and posters, but it is desktop-only.
- 4
Microsoft PowerPoint
Desktop (Windows / Mac)✓ Opens .odtPaid (Microsoft 365 or Office)Opens .odp files, which is handy if the presentation needs to join a PowerPoint deck. Formatting, fonts and some effects can differ from the original.
- 5
Google Slides
Browser-based (Google account)✓ Opens .odtFreeImports an .odp uploaded to Google Drive and turns it into a Google Slides deck. Layouts and fonts can change on import, and it does not open .odg drawings.
- 6
Apache OpenOffice Impress
Desktop (Windows / Mac / Linux)✓ Opens .odtFree (open source)Reads .odp natively, and its Draw program handles .odg. It sees far fewer updates than LibreOffice and still needs a desktop install.
- 7
ONLYOFFICE Desktop Editors
Desktop (Windows / Mac / Linux)✓ Opens .odtFreeOpens .odp presentations alongside PowerPoint files at no cost. PowerPoint files are its strong suit, so a LibreOffice slide may not land exactly where it was.
What is an ODP file — and how is an ODG file different?
An .odp file is an OpenDocument Presentation, the slide-show type of the OpenDocument Format (ODF), the open, XML-based standard created by OASIS (approved 2005, published as ISO/IEC 26300 in 2006). It is a ZIP package of XML and pictures holding slides, layouts and speaker notes, and it is the native format of LibreOffice Impress — the counterpart of PowerPoint's .pptx. An .odg file is an OpenDocument Drawing from LibreOffice Draw, used for flyers, diagrams and posters. .otp is the presentation template; .fodp and .fodg are flat single-XML versions.

ODP and ODG file questions
Can PowerPoint open an ODP file?
Yes, Microsoft PowerPoint opens .odp files: choose File › Open and browse to the presentation. Formatting, fonts and some effects can come out differently from LibreOffice Impress, so flip through every slide before presenting. If you don't own PowerPoint, PublishMedia shows the slides in a browser at no cost to view.
How do I open an ODP file in Google Slides?
To open an .odp in Google Slides, upload it to Google Drive, right-click it, and choose Open with › Google Slides. Google turns it into a new Google Slides deck, leaving the original .odp in Drive. Layouts and fonts can change in that import, so compare it with the original if the design matters.
What is an ODG file and how do I open it?
An .odg file is an OpenDocument Drawing, made in LibreOffice Draw or Apache OpenOffice Draw for flyers, diagrams, maps and posters. Open it in LibreOffice Draw on a desktop, or drag it into PublishMedia to view the drawing as a page in any browser at no cost. PowerPoint and Google Slides do not open .odg files.
What's the difference between ODP and PPTX?
An .odp is the OpenDocument Presentation format that LibreOffice Impress saves by default, while a .pptx is the format Microsoft PowerPoint saves by default; both store slides as XML inside a ZIP package. PowerPoint opens .odp and Impress opens .pptx, so simple decks cross over well. Custom fonts, animations and unusual layouts are what tend to change.
Can I open an ODP file on a Mac without LibreOffice?
Yes, a Mac can open an .odp without LibreOffice by using PublishMedia in Safari, Chrome or any modern browser — sign up, drag the file in, and the slides appear. Viewing the slides in PublishMedia costs nothing. Google Slides works too, after converting the file.
Is there a free ODP viewer?
Yes, Publish Media Software (PublishMedia) is a free ODP viewer in the browser: opening and viewing .odp presentations and .odg drawings costs nothing, with no limit on files. LibreOffice Impress is a free desktop option, and Google Slides imports .odp at no cost. In PublishMedia, editing and PDF export need a paid plan.
Why won't my ODP file open?
An .odp file usually won't open because the program you tried doesn't read OpenDocument presentations — photo apps, text editors and PDF readers can't. It may also be password-protected, which PublishMedia can't open, or it may have been cut short while downloading. Try PublishMedia or LibreOffice Impress, and ask the sender for a fresh copy if both fail.
Will my slide transitions and animations work?
No, slide transitions and animations do not play in Publish Media Software (PublishMedia), which shows each slide as a page for checking, editing and printing rather than running a live presentation. They do play in LibreOffice Impress, and usually in PowerPoint. If you need to present with effects, use Impress; if you need handouts or a printed program, use PublishMedia.
Can I turn an ODP presentation into a PDF?
Yes, PublishMedia turns an .odp presentation into a print-ready PDF on a paid plan, with every slide as a page; viewing the slides first costs nothing. LibreOffice Impress also makes PDFs through File › Export as › Export as PDF at no cost if you can install it. A PDF is the safest way to send slides to someone without LibreOffice.

Accurate facts — October 2026
As of October 2026, the .odp (OpenDocument Presentation) and .odg (OpenDocument Drawing) formats belong to the OpenDocument Format, an OASIS standard approved in 2005 and published as ISO/IEC 26300 in 2006. .odp is the native format of LibreOffice Impress and Apache OpenOffice Impress; .odg is the native format of LibreOffice Draw and OpenOffice Draw. Both suites are free and open source for Windows, Mac and Linux. Microsoft PowerPoint opens .odp files and Google Slides imports them, though formatting can change along the way. Fewer mainstream programs open .odg drawings. Templates use .otp, and single-file flat XML versions use .fodp and .fodg. Publish Media Software (PublishMedia) opens .odp, .otp, .fodp, .odg and .fodg files in a web browser, showing each slide or drawing as a page; viewing costs nothing, and paid plans add editing and PDF export.
