ACBR review
A free desktop reader with broad file support, metadata tools, and Komga or Kavita connections.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ACBR is a free desktop app for reading and converting comics, ebooks, and image files on Windows or Linux. It suits readers who want one local tool for comic archives and several ebook formats, alongside image files. Supported formats include CBZ, CBR, CB7, PDF, EPUB, JPG, PNG, WebP, AVIF, FB2, and MOBI 7. Its home screen organizes files through favorites, recent items, and custom lists, making it relevant to solo readers managing a personal collection across supported formats.
The reading controls cover single-page and double-page modes, page fitting, customizable scaling, and rotation. That is a practical set of basic viewing options, but the product does not include panel reading, and a dedicated manga mode is not specified. Readers who prioritize guided panel-by-panel viewing or a specialized manga experience should look for an app whose reading tools are built around those needs. ACBR is a better fit when straightforward page display matters alongside conversion and library utilities.
Beyond reading, ACBR displays and edits comic and ebook metadata, and can convert and resize comics, ebooks, and images. Connections to Komga and Kavita servers add an option for readers whose collections already use those systems; Comic Vine is also listed as an integration. The app is open source and free, with no paid tiers to compare. It is a sensible pick for Windows or Linux users seeking a no-cost combination of reader, converter, and metadata editor, but less suited to anyone who needs cloud synchronization or more specialized reading modes.
