LibreOffice is a productivity suite that is compatible with other major office suites and available on a variety of platforms. It is open source software and therefore free to download, use, and distribute. If you are new to LibreOffice, this appendix will provide some information regarding its history, its community, and some of its technical specifications.

A short history of LibreOffice

The project began when Sun Microsystems released the source code (“blueprints”) for its StarOffice® software to the open source community on 13 October 2000. 1.0, the product, was released on 30 April 2002. Major updates to included version 2.0 in October 2005 and version 3.0 in October 2008. On 26 January 2010, Oracle Corporation acquired Sun Microsystems.

On 28 September 2010, the community of volunteers who develop and promote announced a major change in project structure. After ten years successful growth with Sun Microsystems as founding and principle sponsor, the project launched an independent foundation called The Document Foundation, to fulfill the promise of independence written in the original charter. This foundation is the cornerstone of a new ecosystem where individuals and organizations can contribute to and benefit from the availability of a truly free office suite.

Unable to acquire the trademarked name from Oracle Corporation, The Document Foundation named its product LibreOffice. Continuing the version numbers from, LibreOffice 3.3 was released in January 2011 and version 7.5 was released in February 2023.

In February 2012, The Document Foundation was incorporated in Berlin as a German Stiftung. You can read more about The Document Foundation at:

The LibreOffice community

The Document Foundation’s mission is:

“ facilitate the evolution of the Community into a new open, independent, and meritocratic organizational structure within the next few months. An independent Foundation is a better match to the values of our contributors, users, and supporters, and will enable a more effective, efficient, transparent, and inclusive Community. We will protect past investments by building on the solid achievements of our first decade, encourage wide participation in the Community, and co-ordinate activity across the Community.”

Some of our corporate supporters include GNOME Foundation, Google, Red Hat, and Collabora. Additionally, over 450,000 people from nearly every part of the globe have joined this project with the idea of creating the best possible office suite that all can use. This is the essence of an “open source” community!

With its open source software license, LibreOffice is key in the drive to provide an office suite that is available to anyone, anywhere, for commercial or personal use. The software has been translated into many languages and runs on all major operating systems. New functionality can be added in the form of extensions.

The LibreOffice community invites contributors in all areas, including translators, software developers, graphic artists, technical writers, editors, donors, and end-user support. Whatever you do best, you can make a difference in LibreOffice. The community operates internationally in all time zones and in many languages, linked through the internet at and

How is LibreOffice licensed?

LibreOffice is distributed under both the Mozilla Public License (MPL) 2.0 ( and the GNU Lesser General Public License (LGPL) 3.0+ (

What is open source?

The four essential rights of open-source software are embodied within the Free Software Foundation family of the GNU General Public License (GPL):

The basic idea behind open source is very simple: when programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs.

What are open standards?

An open standard provides a means of doing something that is independent of manufacturer or vendor, thus enabling competing software programs to freely use the same file formats. HTML, XML, and ODF are examples of open standards for documents.

An open standard meets the following requirements:

What is OpenDocument?

OpenDocument (ODF) is an XML-based file format for office documents (text documents, spreadsheets, drawings, presentations, and more), developed at OASIS (, an independent, international standards group. OpenDocument version 1.2 was adopted by the International Standards Organization and named ISO/IEC 26300:2015 standard. In December 2019, ODF 1.3 was approved as a committee specification.

Tip,, and

Unlike other file formats, ODF (ISO/IEC 26300:2015) is an open standard. It is publicly available, royalty-free, and without legal or other restrictions; therefore ODF files are not tied to a specific office suite and anybody can build a program that interprets these files. For this reason ODF is quickly becoming the preferred file format for government agencies, schools and other companies who prefer not to be too dependent on any one software supplier.

LibreOffice 7.5 saves documents in ODF 1.3 Extended by default. LibreOffice can also open and save in earlier versions of the ODF standard, as well as many other file formats, as summarized below.

For a full list of file formats that LibreOffice can read and write, see this Help page:

OpenDocument filename extensions

The most common filename extensions used for OpenDocument documents are:

*.odt for word processing (text) documents

*.ods for spreadsheets

*.odp for presentations

*.odb for databases

*.odg for graphics (vector drawings)

*.odc for charts

*.odf for formulas (scientific formulas and equations)
