FLOSS/fund support for LibreOffice

FLOSS/fund logo

LibreOffice is a volunteer-driven, community open source project, backed by a non-profit entity, The Document Foundation. The vast majority of the foundation’s income is from community support, and we’re happy to announce that FLOSS/fund has made a very generous contribution of $100,000 to support the LibreOffice project and community.

FLOSS/fund is from Zerodha, a financial technology company and India’s largest stock broker. It is built heavily on FLOSS (free, libre and open source software) and gives up to $1 million to support projects around the world.

Kailash Nadh from FLOSS/fund (and CTO at Zerodha) says:

LibreOffice is one of the most consequential and impactful FOSS projects in the world. We also strongly believe that it has played an important role in enabling adoption of the Linux desktop among regular users. This belief in fact comes from our personal experience of transitioning over 1000 non-technical employees at our organisation to Linux over decade ago.

Many thanks to FLOSS/fund for their support. This helps us to improve our infrastructure, pay developers to work on the software, and organise events to share knowledge. Thank you!

San Salvador will host the VII Latin American Congress of LibreOffice in 2026

Conference logo

The Salvadoran Lutheran University (ULS) and the Latin American LibreOffice Project community announce the seventh edition of the LibreOffice Latin American Conference.

Previous editions of the LibreOffice Latin American Conference have been held in person in Asunción (2019), Brasília (2022), Mexico City (2023), Montevideo (2024), and Havana (2025). The 2026 edition will bring the event to El Salvador for the first time, further expanding the reach of the LibreOffice community in Latin America.

ULS, the event’s host, has a long history of involvement with Free Software, most notably through the biannual FESOL (Free Software Educational Fair)—an event held for over 20 years that showcases dozens of projects developed by Computer Science students in areas such as web systems, databases, robotics, and video games, among others.

The conference will take place on November 27 and 28, 2026, with the aim of bringing together users and contributors to share knowledge and experiences related to LibreOffice.

Guest speakers from Mexico, Spain, Brazil, France, and Taiwan will present topics ranging from tutorials on using the applications to ways of collaborating with the project. The schedule will be announced soon on the official event website:

LibreOffice at FrOSCon 2026

FrOSCon logo

FrOSCon is an annual conference dedicated to Free and Open Source Software (FOSS), held in Sankt Augustin (near Bonn), Germany. And this year, the LibreOffice community was there! We hosted a booth featuring information flyers and merchandise, including stickers, pens, coasters, and more.

We engaged in many substantive conversations at the booth about LibreOffice as a project and its specific features. We also discussed TDF’s development plans for web and mobile platforms and encouraged people to get involved in these areas.

Many visitors stopped by saying, “Of course we use LibreOffice” – often contrasting it with Microsoft Word, which is the “standard” or widely used option in corporate environments. We also frequently heard comments like, “I’ve/we’ve already donated.” Clearly, there is a widespread willingness to contribute financially to software that is both high-quality and genuinely free.

Community members at the stand

Visitors were happy to take home coasters or small stickers. LibreOffice supporters often like to place these items where Microsoft-oriented users can be found.

Alongside the project booth, Andreas Mantke gave a presentation in German titled “Where is LibreOffice Headed?” (Wohin führt der Weg von LibreOffice?), in which he discussed the project’s planned development ideas for web and mobile and answered questions from the audience.

We look forward to being at more events in the coming months!

Software Freedom Day 2026: What Freedoms Does Libreoffice Offer

Today, 19 September, is Software Freedom Day, a special day that the free software community celebrates every year on the third Saturday in September all over the world.

It is a good opportunity to look at LibreOffice from a perspective that is often taken for granted: not what the software does, but what it allows users to do and what it does not impose on them.

Free software is defined by four freedoms. LibreOffice guarantees all of them, and from these derives a range of other freedoms that are important for anyone writing a letter, preparing a budget or presenting a project.

The four freedoms

LibreOffice is distributed under the Mozilla Public Licence 2.0, which guarantees every user the four freedoms that define free software:

  1. the freedom to run the programme for any purpose, without any restrictions whatsoever;
  2. the freedom to study how the programme works, thanks to the availability of the source code;
  3. the freedom to modify the programme to suit one’s own needs, both at an individual and an organisational level;
  4. the freedom to redistribute copies of the software, including modified ones, so that other users may also benefit from its advantages.

The freedom to own your own documents

A document belongs to its author only if the format in which it is saved does not belong to someone else. LibreOffice uses the Open Document Format (ODF) as its native format: an ISO/IEC standard, developed at OASIS through a transparent, fully documented process, which no single company can control or modify unilaterally.

This means that a document saved today in ODF format will still be readable in twenty years’ time, either with LibreOffice or with other software that implements the standard. For private individuals, it is a matter of practicality. For public authorities, which have a duty to preserve documents and to communicate with citizens without forcing them to purchase specific software, it is a matter of principle.

The freedom to keep your data private

LibreOffice does not collect data on its operation, and does not require you to create an account. Documents are created, edited and saved on the user’s computer, and remain there unless the user decides otherwise. There is no mandatory link to a cloud service, and no user profile is created on a remote server.

The freedom to work without distractions

LibreOffice does not display adverts and does not prompt users to take out a subscription or sign up for a premium plan. The interface is designed to support users’ work, not to sell additional services.

The freedom to decide on artificial intelligence

LibreOffice does not include any generative AI features. Users who need them can add them via extensions and choose which service to use, including locally running models, whilst users who do not need them do not have to miss out on anything, as there is nothing to miss out on.

The freedom to choose platform and language

LibreOffice runs on Windows, macOS and Linux, and documents transfer seamlessly between systems. The user interface is available in 120 languages, thanks to the work of volunteer translators, including some languages overlooked by commercial software providers. For speakers of those languages, LibreOffice is the only office suite available.

The freedom from licence fees and vendor lock-in

LibreOffice can be used freely – and therefore at no cost – by individuals, businesses and public authorities. There are no subscriptions to take out or renew, and no mandatory updates: users decide when to upgrade to a new version. Furthermore, documents in ODF format can be transferred to any other software without the need for conversion.

The freedom to choose support

Organisations requiring long-term professional support, service level agreements or bespoke developments can purchase these from companies within the LibreOffice ecosystem, which offer enterprise versions of LibreOffice and related professional services. There is complete freedom of choice regarding providers, and changing providers does not require a change of software or document format.

The freedom to participate

LibreOffice is developed by a global community. Anyone can contribute, and not just by writing code: translation, quality assurance, documentation, design, marketing and user support are all activities carried out by volunteers. And those who do not have the time to contribute can support the project with a donation, which helps to maintain its independence.

How to celebrate Software Freedom Day

The simplest way to celebrate Software Freedom Day is to exercise these freedoms: download LibreOffice, save your documents in ODF and share the software with anyone who might need it. And if you’d like to do more, you can find out how to get involved or make a donation to The Document Foundation.

LibreOffice 26.8 and interoperability: preserving what cannot yet be read

LibreOffice 26.8 adds basic support for importing and exporting a range of chart types that Microsoft Office includes in OOXML files: box-and-whisker, funnel, Pareto, radial, treemap and waterfall charts. LibreOffice is unable to display or edit these charts, but it does recognise them, informs the user that the chart type is not yet supported, preserves the underlying definition unchanged, and rewrites it when the file is saved.

At first glance, this appears to be an admission of incompleteness, whereas it is actually an example of what implementing a proprietary format entails when the aim is interoperability – for the benefit of users, rather than a commercial strategy that treats users as mere tools.

What happened

Microsoft added these chart types to Office from 2016 onwards, storing them in a namespace generally referred to as ‘chartex’. The namespace is not part of the ISO/IEC 29500 text approved as an international standard, but is documented separately in Microsoft’s extension documentation.

This is entirely legal and perfectly normal commercial behaviour: a vendor improves its product and the file format evolves accordingly. The consequence, however, is that the format in everyday use is no longer the one that was standardised. The ISO number continues to be cited in tender documents and policy documents, but the files being exchanged are different.

For any implementer other than the vendor, this creates a permanent state of delay. This is not a one-off gap to be bridged with sufficient effort, but a structural delay, as the specifications are in the hands of a vendor that does not publish its release schedule, with priorities defined according to commercial criteria.

Three possible responses

An office suite that encounters a chart it does not recognise has three options:

  1. It can reject the file. This is an honest but pointless solution: the user is left with a document they cannot open and concludes that the software does not work.
  2. It can discard what it does not understand. The file opens, the chart disappears, and the user only realises this when the document is forwarded to a colleague and the chart is no longer present. This is the most damaging outcome, as the loss occurs silently and the blame falls on whoever opened the file last.
  3. They can retain what they are unable to display. The user is informed that this type of chart is not supported, so they see a placeholder rather than a blank space, and the underlying definition remains intact when the document is transferred from one application to another. The document is restored in full when returned to the source application.

LibreOffice 26.8 adopts the third option, the only one of the three that respects the fact that the document belongs to the user rather than to the software – or, indeed, to the company that develops the software.

Unfortunately, there is a limitation, and this is an exception. Charts with regional maps contain extensive geographical information that LibreOffice is unable to preserve. The chart type survives the import-export cycle, but very little of its content remains intact.

Why this is important beyond charts

The Chartex case is of limited scope. The model, however, is not.

All organisations whose documents are written in a format controlled by a single vendor accept a dependency they are unable to manage, because the specifications may change without notice, with the addition of features that are only understood by a single implementation.

Nothing untoward needs to happen for the organisation’s archives to become progressively more difficult to read by all other software.

The Open Document Format is not immune to change, but it changes differently. Revisions are proposed, discussed and approved by a technical committee at OASIS, whose work is public, and are published as version specifications that anyone is free to implement.

An implementer wishing to support ODF 1.4 can read the ODF 1.4 specification and put it into practice. This is the only difference, and it is sufficient.

The bidirectional preservation of unsupported features is what distinguishes a responsible implementation under current conditions, but it does not constitute an improvement on those conditions. LibreOffice is the only office suite to adopt this approach, in order to protect users and the content within their documents.
