ONLYOFFICE

ONLYOFFICE delivers enterprise-grade document collaboration with seamless Microsoft Office compatibility, available as cloud service, self-hosted solution, or integrated into 40+ platforms.

The suite provides powerful editors for text documents, spreadsheets, presentations, fillable forms, PDFs, and diagrams—all with real-time collaborative editing supporting Fast Mode (instant updates) or Strict Mode (private editing with manual sync).

Full compatibility with Office Open XML formats (.docx, .xlsx, .pptx) ensures flawless file exchange with Microsoft Office users. Advanced formatting, complex formulas, pivot tables, macros, and mail merge all work seamlessly without conversion issues or layout breaks.

Collaboration features include track changes with accept/reject workflows, threaded commenting with @mentions, version history with recovery, document comparison, and integrated chat. Share documents with granular permissions controlling viewing, editing, commenting, downloading, and printing.

Choose from three editions: Community (free, open-source, AGPLv3), Enterprise (advanced features, professional support), or Developer (white-label integration for your applications). Deploy on Windows, Linux, Docker, or Kubernetes. Mobile apps for iOS and Android plus desktop editors for Windows, macOS, and Linux ensure access from any device.

With plugin support extending functionality, integration capabilities for Nextcloud, Odoo, WordPress, Moodle, and more, plus on-premise deployment for complete data sovereignty, ONLYOFFICE empowers teams to collaborate effectively while maintaining control over sensitive documents.
