Dolphin Context Menus

Custom Right-Click Menus in Dolphin

KDE's Dolphin file manager supports custom right-click context menus via Service Menus. Below are two ready-to-use menus: one for image conversion/editing (using ImageMagick) and one for video conversion/audio extraction (using FFmpeg).

Prerequisites

sudo dnf install ImageMagick ffmpeg

Make them executable

Both .desktop files must be executable or Dolphin will show a permission error:

chmod +x ~/.local/share/kio/servicemenus/convert-images.desktop
chmod +x ~/.local/share/kio/servicemenus/convert-videos.desktop

The submenus will appear immediately — no restart needed. Right-click any image or video in Dolphin to see the new options. They also work with multiple selected files at once.

note

Video conversions open a Konsole terminal window so you can see FFmpeg's progress.
