PhotoQt v4.7

Flatpak

PhotoQt is available on Flathub. If you don't have Flatpak installed yet, please refer to the official installation instruction by Flatpak.

With Flatpak installed on your system, you first need to add Flathub as a remote (if not already added):

$ flatpak remote-add flathub https://flathub.org/repo/flathub.flatpakrepo

Following this, you can install PhotoQt by running:

$ flatpak install flathub org.photoqt.PhotoQt

After the above has completed successfully, you can run PhotoQt using this command:

$ flatpak run org.photoqt.PhotoQt

Flatpaks integrate very well in various window managers, like KDE or Gnome. They should show up next to all other installed apps and can be launched and used like any other application.

Better video performance

Video playback in PhotoQt when installed as Flatpak can be rather slow and choppy. This can be fixed by also installing the extension Flatpak org.freedesktop.Platform.ffmpeg-full that adds better codec support to PhotoQt (and other Flatpaks). PhotoQt supports both the current and previous version, so if you have version 23.08 or 24.08 already installed (you can check with flatpak list) then you are all set. Otherwise you can install it by running flatpak install flathub org.freedesktop.Platform.ffmpeg-full and selecting the desired version.
