LibreOffice is a powerful office suite – its clean interface and feature-rich tools will help you unleash your creativity and enhance your productivity. LibreOffice includes several applications that make it the most powerful 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).
LibreOffice is compatible with a wide range of document formats such as Microsoft® Word, Excel, PowerPoint and Publisher. But LibreOffice goes much further with its native support for a modern and open standard, the OpenDocument Format (ODF). With LibreOffice, you have maximum control over your data and content.
