The best open source office suite continues to evolve, while maintaining its focus on privacy and digital sovereignty
Berlin, 20 August 2025 – The Document Foundation announces the release of LibreOffice 25.8. This latest version of the market-leading free open source office suite maintains its focus on digital sovereignty and privacy protection. It offers individuals, organisations, and governments total control over their data and the most comprehensive productivity tools.
In a global context of growing concern about data privacy, cloud lock-in, and surveillance capitalism, LibreOffice 25.8 provides concrete solutions.
Open Source: The source code is available for inspection and is completely free from proprietary technology constraints.
Privacy and Control: LibreOffice does not collect personal data, usage metrics or diagnostic information, and complies with the data protection regulations required by public administration implementations (GDPR).
Local Execution: all features are executed locally on the user’s computer, without the need for an internet or cloud connection.
Self-Hosted Collaboration: Integration with on-premises cloud solutions, such as Nextcloud, enables teams to collaborate without sharing information with Big Tech.
User Interface: the Welcome/What’s New dialog now offers access to the user interface picker and appearance options, allowing new users to leverage LibreOffice’s flexible UI and personalise the look and feel according to their preferences.
Performance: everything is faster, from startup to scrolling through large documents – with significant speed improvements on less powerful machines.
Better Interoperability with Microsoft Office files, with more accurate handling of DOCX, XLSX and PPTX files and fewer formatting issues, thanks to changes such as:
There are, of course, other important new features, such as the ability to export to the PDF 2.0 format, and several new ScriptForge library services. The complete list is available here: wiki.documentfoundation.org/ReleaseNotes/25.8.
In terms of operating system support changes, LibreOffice 25.8 will no longer run on Windows 7 or 8/8.1 versions. It is also the last version to run on macOS 10.15. Support for x86 (32-bit) Windows versions is deprecated.
The Document Foundation collaborates with a global network of certified partners who offer enterprise-grade support and maintenance, customised features and integrations, and assistance with user migration and training. A full list of partners can be found here: www.libreoffice.org/get-help/professional-support/.
LibreOffice 25.8 is completely free and offers a viable alternative to proprietary office suites for individual users, schools, businesses, and public institutions. It contains no advertising, data tracking, or subscriptions.
It is ideal for students and teachers who need reliable tools for documents, presentations and data analysis, as well as for home users and freelancers looking for a solid, free alternative to Microsoft Office/365 or Google Docs. It is also ideal for public administrations and companies that value data sovereignty and the long-term accessibility of documents.
LibreOffice 25.8 reaffirms our dedication to safeguarding the freedom and privacy of end users in the digital age. With this new release, we ensure that personal information stays where it belongs – with the individual. LibreOffice gives end users full control over their documents, helping them to avoid reliance on third-party platforms that might compromise their data or privacy. It’s about empowering users to work securely, independently and confidently, said Eliane Domingos, chairwoman of The Document Foundation.
LibreOffice 25.8 is available for Windows, macOS and Linux, with versions for Intel and ARM/Apple processors, at www.libreoffice.org/download/.
The Document Foundation is a non-profit organisation that promotes open document formats and develops LibreOffice, the market-leading free open-source office suite. Its mission is to empower individuals and organisations to maintain control over their data and tools in an increasingly digital world dominated by closed platforms.

LibreOffice does not include artificial intelligence (AI) out-of-the-box. But many users want AI features in the suite – so we encourage developers to make them available as optional extensions. And that’s what Igor Támara did, creating the “Stable Diffusion for LibreOffice” extension for AI-generated images powered by AI Horde (a volunteer crowd-sourced distributed cluster of image generation workers).
We talked to Igor about the extension – here’s what he had to say:
You write some text describing an image, and get an AI image generated from the given text. You can tweak parameters, choose a model and use the best result on written documents, presentations or the place you prefer. The images are generated on volunteer GPUs through AI Horde.
Two weeks ago, starting from a Gimp plugin as a base. I’m brand new to the LibreOffice project, and started it as a macro to get this functionality in the software. One week later I put it on GitHub.
Later on I got help from friendly people on the forum to turn it into an extension. I also joined the the chat and filled some requests in the bug tracker.
Be aware that the text you provide is sent to AI Horde and seen by the machines that create the image, so do not send sensitive data. Also, you can get better results if you send the description of the desired image in English. You are encouraged to try different languages to see the results.
You need internet connection to use it. If you wanted to create images locally on your machine, it would take time to configure your environment with local AI models, with gigabytes of memory dedicated to this purpose, and maybe processing for hours to get something useful.
Sometimes the text can be marked as NSFW (“not safe for work”) – in which case you end up with black and white text saying so.
For now, the extension works in Writer and Impress; when invoked from other LibreOffice components, it opens a new text document and inserts the image along with the provided text.
The roadmap includes:
Report any problems you find, and help to translate into your language. Please do so by filling an issue with your intention saying which language.
If you have a GPU (and good graphics hardware in general), you can volunteer as a worker joining the horde, to add to the computing power – and you can earn kudos to have higher priority when you need it.
If you work with a friendly company that wants to make use of the existing hardware, you can join the horde too.
One of the purposes of AI Horde is to aid education, having a special program for that.
This plugin and AI Horde are all open source, so everyone can learn and be as transparent as possible in this changing and revolutionary world of AI times.
There might be concerns about the use of products and the ownership of work. As I see it, we are always learning by example and reusing what others have invented from thousands of years ago, like how to walk, make fire, communicate, explore, recreate and mix. We can continue to learn and make fair use of resources – and contribute too.
In the digital world, document formats are essential. Proprietary formats such as Microsoft Word’s DOCX or Excel’s XLSX dominate the workplace, but at the same time they lock users into a specific vendor and its business strategies, which tend to exploit users to the maximum in every way. The Open Document Format (ODF) offers an open, standard alternative that protects users and their privacy, promotes interoperability, long-term access and data ownership.
Migrating documents from proprietary formats to ODF is the solution, and although vendors who rely on proprietary formats – not only Microsoft, but also its freeware clones such as OnlyOffice or WPS Office – do everything they can to prevent it, it is very easy and represents a fundamental step forward for users in terms of privacy and digital sovereignty (i.e., ownership of their own content).
This guide breaks down the migration process to make the transition smooth, efficient and sustainable, both at the individual level (where problems are virtually non-existent) and at the enterprise level, where problems exist due to the lock-in strategies of proprietary formats.
Step 1: Understand ODF and its advantages
Step 2: Document inventory to define conversion priorities and estimate the effort required for migration
Step 3: plan the migration workflow
Step 4: Converting documents to ODF format
Step 5: Monitoring the migration
Conclusion
Migrating from proprietary formats to ODF is a strategic move, both individually and for businesses, towards openness, content control and document protection for the future. In a business environment, it requires careful planning and user involvement, but the benefits in terms of flexibility, interoperability and cost savings are well worth the effort.
