Calibre-Web is a web application that puts an existing Calibre eBook library behind a browser-based interface. You can browse and filter its catalog, read certain formats in a browser, download books, or connect compatible reading apps through OPDS. It is a library interface, not an e-book store.
What Calibre-Web does
The Calibre-Web project describes the app as “a web app providing a clean interface for browsing, reading, and downloading eBooks using a valid Calibre database.” In practice, an administrator points it to the folder containing an existing Calibre library database; Calibre-Web then presents that collection on the web.
Its documented library tools include filtering by title, author, tags, series, and language, along with custom shelves, metadata editing, and user permissions. Which features are available can depend on the release and configuration installed. See the Calibre-Web project README for current project details.
Ways to read or get books from the library
Read in a web browser
The project documents browser reading for these formats: .txt, .epub, .pdf, .cbr, .cbt, .cbz, and .djvu. This is the project’s stated support list; the formats available on a particular installation may depend on its release and configuration.

Download a book
You can download books from the web interface and then open them in a separate reader app or transfer them to a device. This route does not depend on the reader app having OPDS support.
Connect a compatible reader app with OPDS
Calibre-Web documents an OPDS feed. OPDS is a catalog interface that supported reading apps can use to browse a calibre library and download books. The calibre manual describes this general workflow, but app support varies; the presence of an OPDS feed does not mean every reading app or e-reader can connect to it. See the calibre manual’s OPDS guidance for the reader-app side of the process.
Rank #2
- Calibre Companion (CC), recommended by calibre developers, is three applications in one:
- a superb device-based calibre library organizer
- a high-performance WiFi-based calibre device emulator
- a client that can access calibre content servers and fetch information from calibre libraries stored in the cloud.
Send books to an e-reader or sync Kobo
The project also lists sending eBooks to e-readers and syncing Kobo devices as features. These descriptions do not establish compatibility with every device or a particular current Kobo model, so check the documentation for the Calibre-Web release and device you plan to use.
Does Calibre-Web require calibre’s conversion tool?
No—not just to browse an existing library. The project describes the calibre conversion tool as an optional addition for on-the-fly conversion used by certain e-reader sending or editing features. Add it only if you need those conversion-dependent functions; it is not a general prerequisite for browsing the catalog.
What you need to set it up
Calibre-Web needs an existing Calibre library database, and its setup information asks the administrator to select the folder where that library lives. Installation methods and dependencies can change, so use the current project documentation for instructions that match the release you install. The README describes pip installation and references other installation examples.
