File Sync & Share

Securely sync files across devices via desktop and mobile clients. Granular sharing controls allow per-user, group, or public link sharing with expiration and password rules. File locking prevents edit conflicts.

End-to-End & Server-Side Encryption

Protect data at rest and in transit. End-to-end encryption ensures only intended recipients decrypt files, while server-side encryption secures data on disk.

Nextcloud Talk

Host private audio, video conferencing and chat with WebRTC. Features include phone-number SIP integration, call forwarding, and moderator controls. Integrates with Whiteboard and Office apps for collaborative meetings.

Nextcloud Office

Edit documents collaboratively in-browser using Collabora Online or OnlyOffice. Real-time co-authoring, version history, and document comments streamline team workflows.
