LibreOffice & Thunderbird - Upgrade from Microsoft Office

Do more – easily, quickly

LibreOffice is a powerful and free office suite, a successor to OpenOffice(.org), 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).

Great-looking, well-structured documents

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, thanks to its powerful styles system and structuring tools.

Use documents of all kinds

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.

Get more features with extensions

Beyond the many features shipped by default, LibreOffice is easily extensible through its powerful extensions mechanisms. Get even more features and document templates on LibreOffice's dedicated websites.
