Finally, documents that look good

Use documents of all kinds
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 – and you can export your work in many different formats including PDF.

Free as in Freedom, now and forever

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.
