Bookworm is an open-source desktop ebook reader for Elementary OS and other Linux distributions. It suits readers who keep books in local folders and want one application for common ebook and comic formats. Support covers EPUB, PDF, MOBI, FB2, CBR, and CBZ, while grid and list views provide two ways to browse a collection. Its GPL-3.0 license also makes it a clear fit for readers who prefer open-source software.

Library organization is a central strength. Bookworm can load books automatically from multiple folders, then provides metadata editing, sorting, and search for maintaining a more usable collection. Inside a book, readers get bookmarks, annotations, table-of-contents navigation, and in-book text search. These tools give the application more depth than a basic file opener, particularly for people managing a varied personal library. The focus remains on reading and local organization rather than a broader content service or connected ecosystem.

Reading customization is similarly well covered. Light, sepia, and dark reading profiles can be paired with controls for font, zoom, margins, and line width, making it possible to adjust the display for different books and preferences. Installation can be handled through Linux packaging options, or the project can be built from source. Bookworm is a strong choice for Linux users seeking a free, open-source reader with broad format support and useful library tools. Readers who require access beyond Linux or a synchronized reading experience should choose a different type of ebook application.
