Create, view and edit text documents, spreadsheets and presentations of any size and complexity. Work on documents of most popular formats: DOCX, ODT, XLSX, ODS, CSV, PPTX, ODP, etc. Deal with multiple files within one and the same window thanks to the tab-based user interface.

Highest compatibility with Microsoft Office formats

Real-time collaboration within your favorite cloud

Connect ONLYOFFICE Desktop Editors to the cloud platform of your choice: ONLYOFFICE, Nextcloud or ownCloud to collaborate on documents with your team – co-edit in real time, review, comment and interact using chat.
The ONLYOFFICE suite brings to the table most capabilities one would expect from such a suite and paves the way to team collaboration, without making the user deal with complex customization and configuration details.

End-to-end encryption reinforced by blockchain

Encrypt your documents, data transfer, and even temporary files while co-editing at both ends. Work, store and collaborate on documents privately. Currently available as a developer preview.

Extending your editing capabilities

Take the most of your editing with the collection of third-party plugins. Insert a YouTube video, add special symbols or a ClipArt object, automatically translate any word or sentence, highlight code, etc.
Do even more! Create your own plugin using our API documentation and ready-to-use examples available on GitHub.
