K3b

What K3b is

K3b is a free Linux application for burning CDs and DVDs, developed by KDE. Users create projects from the file menu and add data before burning. The Tools menu includes CD copying and DVD formatting. Selecting a CD or DVD drive displays its contents and offers additional actions, including audio CD ripping. K3b supports ISO and CUE image formats. Linux users can install it through an AppStream application store or their distribution’s package manager. KDE provides links to a forum, the #k3b Libera.chat channel, a bug-reporting page and a bug list for support and issue reporting. KDE describes its software as free and open source, generally transferring end-user information only after an explicit user action. The listed Free plan costs nothing, with no free trial listed. The project page lists version 26.08.2, released 2026-10-08. KDE has built and distributed free, open-source software since 1996.

Who it suits

It suits Linux users who need disc-burning, copying, formatting or audio-ripping tools. It is also a fit for users working with ISO or CUE images.

Getting started

1. Visit the K3b page on the KDE website.
2. Install K3b through an AppStream application store or your Linux distribution’s package manager.
3. Create a project from the file menu and add data to prepare it for burning.

Verdict

K3b offers a focused set of CD and DVD tools at no charge on Linux. Its usefulness depends on having compatible optical hardware and needing disc-based workflows.
