ACBF Viewer

Comic books don't only come on physical paper but also in digital format, and there are many types of files they are wrapped in. If you happen to have ACBF, CBZ/CBR or ACV comic files on your PC but don't know how to open them, you can turn to ACBF Viewer.

Based in Python and requiring no installation on the system, this application is currently available on Windows and Android. It's free and open-source, which means that skilled developers can take a look at its code and even modify it to create bigger and better versions.

As far as the interface is concerned, ACBF Viewer is not flashy in any way, having a window similar to the appearance of Java-based photo viewers. On the bright side, the buttons and menus are exactly where you expect them to be since the program takes a non-complicated approach.

After opening a comic with the integrated file browser, you can turn pages using the mouse scroll, arrow keys or buttons on the upper bar, as well as zoom in to view finer details. To immerse yourself in the comic, you can switch to fullscreen.

The book's table of contents can be explored to jump through chapters. It's also possible to rotate pages if they were wrongfully placed by the author, as well as make image adjustments to the brightness, contrast, sharpness or saturation if your monitor is not showing graphical content properly.

Collections of comic books can be added to a library of ACBF Viewer and sorted by title, series, author, publisher, publish date, languages, rating. For very large collections, you can set filters (e.g. image format, license, frames definition). The library summary can be exported to CSV. By the way, unless you know this by now, you can download comics from ACBF.info (completely free).

Program settings can be configured for the layout (e.g. popup text, process bar), fonts, images (e.g. stretch, remove border, autorotate, resize filter) and library (e.g. books per page, default sort order).

Taking everything into account, ACBF Viewer grants easy access to comic book files in ACBF, CBZ/CBR or ACV format, wrapped in a user-friendly interface and backed by practical options. If you want to fix typos and other comic book inaccuracies, you can use ACBF Editor.
