LibreOffice is developed by The Document Foundation (TDF), a non-profit organization based in Germany. Founded in 2010, TDF promotes open-source software by continuing the work of the OpenOffice community to provide a free and compatible alternative to Microsoft Office. LibreOffice includes applications like Writer (word processing), Calc (spreadsheets), and Impress (presentations), all designed to ensure document compatibility and support the Open Document Format (ODF).
