Jellyfin Web is the browser-based frontend for the Jellyfin media server, providing the user interface for browsing, playing, and administering a self-hosted media collection. It functions as a cross-platform media client that works across desktop and mobile browsers, offering a dashboard for server configuration, user management, and plugin administration. The web client serves as the primary interface for organizing and streaming personal media libraries, including movies, TV shows, music, and photos.
The web interface supports a range of media management capabilities, including library organization with filtering, sorting, and duplicate grouping, as well as live TV streaming from tuner backends with automatic recording scheduling. Playback features include direct play for compatible formats, on-the-fly transcoding via FFmpeg for unsupported media, HDR to SDR tone mapping, and synchronized playback across multiple devices. Subtitle management covers downloading from online databases, extracting embedded subtitles, and generating subtitles using local AI models.
Server administration through the web interface includes user account setup, metadata language preferences, home screen customization, and visual theme management. The interface also provides access to plugin installation through a hosted catalog, custom CSS styling, and playback statistics tracking. Security controls such as HTTPS encryption, LDAP authentication, and per-user remote access restrictions are configurable through the dashboard.
