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

  • view and annotate pdf documents
  • read comics and epub files on linux
  • embed a document viewer in another KDE application
  • fill and save pdf forms
  • read documents on a mobile device

When to choose

  • you need a free, feature-rich PDF and multi-format document viewer on Linux or KDE Plasma
  • you want native PDF annotation and form support
  • you want to embed document viewing in a KDE app via KParts

When to avoid

  • you need a lightweight minimal PDF viewer
  • you require a viewer deeply integrated with non-KDE desktop ecosystems
  • you need advanced PDF editing beyond annotations
