Was ist K3b?
K3b started in the early 2000s as a KDE project to bring robust disc‑burning capabilities to Linux, matching the feature set of Windows rivals like Ashampoo and Nero. Over two decades it has matured, integrating with KDE’s file manager and offering a clean, native interface. It’s aimed at users who need reliable disc creation without leaving the desktop.
The application is geared toward both casual users and power burners: it supports ISO extraction, audio CD rip, and multi‑track burning. Its KDE look feels familiar to those used to Windows GUIs, but it follows Linux conventions such as drag‑and‑drop and context menus.
Compared with ImgBurn or Nero, K3b is free, open‑source, and fully integrated into the KDE ecosystem. It lacks some advanced features of paid Windows tools, but it delivers the core burning functions with a stable, well‑tested code base.
Ideal für: Users who need a reliable, free disc‑burning tool that fits naturally into the KDE desktop.

K3b unter Linux installieren

If you come from Ashampoo, ImgBurn, or Nero, you’ll notice that K3b uses KDE’s native dialogs and shortcuts (e.g., Ctrl+N for new project, Ctrl+S to start burn). File formats are the same: ISO, ISO9660, UDF for DVDs, and Blu‑ray BD‑ISO. Instead of a wizard, K3b relies on a project window where you add files, set burn options, and then click the burn button. Drag‑and‑drop from Dolphin works like Windows Explorer, and the burn status window gives real‑time progress and error logs. For ISO creation, just select “Create ISO image” and choose your source folder.
