LibreOffice is Free and Open Source Software. Development is open to new talent and new ideas, and our software is tested and used daily by a large and devoted user community.
LibreOffice is a powerful and free office suite, used by millions of people around the world. Its clean interface and feature-rich tools help you unleash your creativity and enhance your productivity. LibreOffice includes several applications that make it the most versatile Free and Open Source office suite on the market: Writer (word processing), Calc (spreadsheets), Impress (presentations), Draw (vector graphics and flowcharts), Base (databases), and Math (formula editing).
Your documents will look professional and clean, regardless of their purpose: a letter, a master thesis, a brochure, financial reports, marketing presentations, technical drawings and diagrams. LibreOffice makes your work look great while you focus on the content.
LibreOffice is compatible with a wide range of document formats such as Microsoft® Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx) and Publisher. But LibreOffice goes much further with its native support for a modern and open standard, the Open Document Format (ODF). With LibreOffice, you have maximum control over your data and content – and you can export your work in many different formats including PDF.
LibreOffice is Free and Open Source Software, available for everyone to use, share and modify, and produced by a worldwide community of hundreds of developers. Our software is tested and used daily by a large and devoted user community – we’re open to new talent and new ideas, so get involved and influence its future.
Built on a strong heritage
LibreOffice is a successor to OpenOffice.org (commonly known as OpenOffice), which in turn was based on StarOffice. Many years of development have gone into the software, and it has been used in its various incarnations by millions. Today, LibreOffice is by far the most active continuation of the OpenOffice.org codebase, with releases every six months and hundreds of contributors. Also, LibreOffice uses libraries from the Document Liberation Project, handing control back to content creators.
LibreOffice for your business
You can download and use LibreOffice for free, but bear in mind that it doesn’t include technical support or other value-added services. If you want to deploy LibreOffice in a business, we strongly recommend sourcing a LibreOffice-based solution from one of our ecosystem partners.
Edit all kinds of documents
Writer has all the features you need from a modern, full-featured word processing and desktop publishing tool. It’s simple enough for a quick memo, but powerful enough to create complete books with contents, diagrams, indexes, and more. You’re free to concentrate on your message, while Writer makes it look great.
Impeccable documents in just a few clicks
Your documents look better than ever when they’re made with LibreOffice. You can choose and apply fonts that are on your computer, and set and customize styles for virtually every part of your document. With the AutoCorrect dictionary you can trap typos and spelling mistakes on the fly. The AutoCorrect dictionary checks your spelling as you type (it’s easy to deactivate if you want to). If you need to use different languages in your document, Writer can handle that too.
LibreOffice helps you all the way through your document
Wizards takes all the hassle out of producing standard documents such as letters, faxes, agendas and minutes, and make short work of more complex tasks such as mail merges. Type more efficiently with AutoComplete, which can suggest commonly-used words and phrases to complete what you started typing, using the built-in dictionary and by scanning the documents you open. Document templates are shipped by default – there’s no need to create complex documents, because we’ve built them in for you!
The spreadsheet for everyone
Calc is the free spreadsheet program you’ve always needed. Newcomers find it intuitive and easy to learn, while professional data miners and number crunchers appreciate the comprehensive range of advanced functions. Built-in wizards guide you through choosing and using a comprehensive range of advanced features. Or you can download templates from the LibreOffice template repository, for ready-made spreadsheet solutions.
All the professional features you need
Styles and direct formatting makes it easy to apply flexible cell formatting options, including freely rotating contents, templates, backgrounds, borders and much more. Become a spreadsheet expert by using templates with built-in functions, so that you can reuse a pre-prepared sheet and just focus on the immediate work.
The Scenario Manager allows “what if …” analysis at the touch of a button. For instance, you can compare profitability for high, medium and low sales forecasts.
Calc‘s solver component lets you solve optimization problems in which the optimum value of a particular spreadsheet cell has to be calculated based on constraints provided in other cells.
Unleash your data
Advanced DataPilot technology makes it easy to pull in raw data from corporate databases, and then cross-tabulate, summarise, and convert it into meaningful information. Real-time data streams can now be integrated in sheets and reports, and factored in calculations.
Collaborate with others
You can perform collaborative work on spreadsheets, thanks to Calc‘s multiple-user support. Just share a spreadsheet so that other users can easily add their data to it. The spreadsheet owner can then easily integrate the new data in just a few clicks. This collaboration feature helps to avoid editing conflicts.
Excel at Excel®
While Calc saves spreadsheets in its native Open Document Format (.ods), it can also open and save files in Microsoft Excel format for sending to people still locked into Microsoft products. If you only need to make your data readable, but on a wide range of devices and platforms, you can easily export to Portable Document Format (.pdf). Calc can read .xlsx files created with Microsoft Office for Windows and macOS.
In Impress, creating and editing slides is very versatile thanks to different editing and view modes: Normal (for general editing), Outline (for organizing and outlining your text content), Notes (for viewing and editing the notes attached to a slide), Handout (for producing paper-based material), and Slide Sorter (for a thumbnail sheet view that lets you quickly locate and order your slides).
Rich content for outstanding presentations
Impress has a comprehensive range of easy-to-use drawing and diagramming tools to add style and sophistication to your presentation. What’s more, you can bring your presentation to life with slide show animations and effects. The Fontworks tool lets you create attractive 2D and 3D images from text. Impress enables you to build and control 3D scenes incorporating a large variety of objects and components.
Stay in control – Master your performance
When the time comes to present your work, a powerful Slide Show mode gives you total command over how your slides are displayed and sequenced, so that you can focus on addressing your audience (which slides get shown; manual or timed slide transition; pointer visible or invisible; navigator visible/invisible; and much more).
Impress supports multiple monitors, and its bundled Presenter Console extension gives you even more control over your slide show, such as the ability to see the upcoming slide, view your slide notes, and control the presentation timer while the audience is looking at the current slide.
A touch of creativity
Take your presentations to the next level and save even more time by downloading templates from the LibreOffice template repository.
Eye-popping graphic documents
Draw lets you produce anything from a quick sketch to a complex plan, and gives you the means to communicate with graphics and diagrams. With a maximum page size of 300cm by 300cm, Draw is a an excellent package for producing technical drawings, brochures, posters and many other documents. Draw lets you manipulate graphical objects, group them, crop them, use objects in 3D and much more.
Powerful diagraming and flowcharting
Design powerful and intuitive flowcharts with Draw. Smart connectors make it easy to build flowcharts, organization charts, network diagrams and much more, even if you’re not a naturally talented artist. You can define your own “glue points” for connectors to adhere to, for precise and easily repeatable positioning. Dimension lines automatically calculate and display linear dimensions as you draw.
Create your own picture galleries
Draw enables you to manipulate pictures and images in many ways – you can even create an entire photo album with it. Its powerful engine allows the conversion of images from and to an impressive range of image and document formats.
A powerful manager for all databases
Base is a full-featured desktop database front end, designed to meet the needs of a broad array of users. Base caters to power users and enterprise requirements, providing native-support drivers for some of the most widely employed multi-user database engines: MySQL/MariaDB, Adabas D, MS Access and PostgreSQL. In addition, the built-in support for JDBC- and ODBC-standard drivers allows you to connect to virtually any other existing database engine as well.
A fast and flexible database
Base comes configured with the full HSQL relational database engine. It’s an ideal solution for everyday jobs, and for people requiring an easy-to-understand, simple-to-use system: data is stored right inside the Base file, and you also get native support for dBase flat files. LibreOffice Base provides wizards to help users who are new to database design (or just new to the software) to create tables, queries, forms and reports, and it comes supplied with a set of pre-defined table definitions for tracking assets, customers, sales orders, invoices and many other common and useful items.
Full integration with other LibreOffice applications
Base is much more than a tool that can be used for standalone purposes – it’s also perfectly integrated with LibreOffice’s other applications. Base can supply address book data for mail merges in Writer using the LDAP protocol, or various address book formats. In addition, Base can be used for creating linked data ranges in Calc files, for data pilot analysis or as the basis for charts.
The neat equations and formulas editor
Math is LibreOffice‘s formula editor, and can be invoked in your text documents, spreadsheets, presentations and drawings, enabling you to insert perfectly formatted mathematical and scientific formulas. Your formulas can include a wide range of elements, from fractions, terms with exponents and indices, integrals, and mathematical functions, to inequalities, systems of equations, and matrices.
You can start Math either as a stand-alone application directly from the LibreOffice Start Center or directly from within other LibreOffice applications such as Writer, Calc, Impress and Draw.
