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 our dedicated websites.

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 the actively developed successor project to 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.
