Okular is KDE's universal document viewer for formats including PDF, PostScript, EPUB, Comic Book, and images, with support for annotations. It ships as a desktop shell, a mobile Kirigami app, an embeddable KParts plugin, and generator backends for various document formats.
Use cases

- read comics and epub files on linux

When to choose
