What is calibre?
calibre brings an e-book collection into one searchable desktop library. Browse by author, title or tags, download missing covers and metadata, and use custom fields to organize your books. Its built-in viewer lets you read without leaving the library manager, while the editor works on EPUB and AZW3 books.
For moving books between reading apps and devices, calibre converts supported formats such as EPUB, MOBI and AZW3 and transfers books to compatible e-readers. The Content server also makes your library available through a web browser. Conversion is for books without DRM: calibre does not open or convert DRM-protected books. PDF input is another important boundary, especially for scanned pages and multi-column layouts.
The selected download is the calibre 9.17.0 Windows 64-bit MSI installer. The publisher lists Windows 10 version 1809 or higher for this package. calibre Portable is a separate download that keeps libraries and settings together; it is not the MSI linked here.
What it offers
- Search and sort your library using authors, tags and other metadata; add custom fields for your own organization.
- Download book metadata and covers, or edit them yourself.
- Read books in the built-in viewer and edit EPUB or AZW3 books with the e-book editor.
- Convert supported e-book formats and transfer books to compatible reading devices.
- Browse and read your library in a web browser through the calibre Content server.
Good to know
- calibre does not open or convert DRM-protected e-books; format conversion does not remove DRM.
- PDF conversion does not support complex, multi-column or image-based documents, and cannot extract tables or vector images from PDF input.
- The selected Windows installer requires Windows 10 version 1809 or higher. The publisher directs older Windows users to earlier calibre releases instead.
