Frequently asked questions

Collabora and LibreOffice are related, but not the same. LibreOffice is a community-driven office suite maintained by The Document Foundation (TDF), while the Collabora team contributes to the LibreOffice codebase and also offers its own products based on it: Collabora Office for desktops and Collabora Online for the web.

Collabora supports Microsoft Office (OOXML) file formats, although some deviations when rendering DOCX, XLXS, or PPTX files are possible. To achieve maximum fidelity, using the OpenDocument Format (ODT, ODS, ODP, etc.) is recommended.

Collabora Online emphasizes security by rendering only what the user sees, rather than handing over the editable file itself. The raw document remains on the server.

Collabora is an open source software company best known for its LibreOffice-based office suite Collabora Office. Its web-based version, Collabora Online, is one of three office suites available for Nextcloud, in addition to Euro-Office and Thinkfree Office.

Yes, Collabora Online supports mobile devices and features a dedicated mobile interface.
