LibreOffice

LibreOffice offers 97% compatibility with Microsoft Office documents, handling complex macros and tracked changes better than any other free alternative. The 2026 update reduces PDF export time by 22% and introduces a redesigned interface with over 60 customizable templates. At a compact 350 MB, it is 30% lighter than #5 GIMP's install footprint, making it an efficient productivity choice. However, it lacks the real-time collaboration features that #9 OnlyOffice provides natively, which may matter for teams.
