OnlyOffice is a powerful office suite that offers seamless document sharing and collaboration experiences for individuals and teams. In terms of sharing, it's extremely convenient. With just one click, you can set access permissions for individuals, entire departments, or teams. It also supports linking to external users. The advanced document permissions are rich. Users can choose from modes such as editing, reviewing, commenting only, form - filling, or viewing. When collaboratively editing spreadsheets, other users can apply their own filtering conditions without disturbing the collaborating authors. It can also restrict printing, downloading, and copying, and set time limits and passwords for externally shared files. The collaboration features are a highlight of OnlyOffice. It provides two co - editing modes: real - time and paragraph - locking, along with functions like reviewing, version history, commenting, and mentioning. Real - time communication is also very convenient. Users can discuss document content in the built - in chat room or on Telegram, and conduct audio and video calls using the Jitsi or Rainbow plugins. The version and revision control system allows users to have full control over their documents. Through revision tracking, even the slightest changes can be viewed, and milestones can be marked with file versions. The document embedding function enables direct embedding of documents into websites, providing instant views for web visitors without the need to download additional programs. In addition, users can use the WebDAV client to collaborate with other users on remote network servers to co - edit and manage files.
