LibreOffice 6.4 is now available as a free office suite from The Document Foundation. This major new version offers improved performance, particularly when opening and saving spreadsheets and presentations, along with excellent compatibility with DOCX, XLSX, and PPTX files.
LibreOffice provides the highest level of compatibility in the field of office suites, starting from native support for the Open Document Format (ODF) - with security features and interoperability superior to proprietary formats - to nearly perfect support for DOCX, XLSX, and PPTX files. Additionally, LibreOffice includes filters for numerous legacy document formats and, as such, is the best interoperability tool on the market.
