User interface

The idea is to have a uncluttered, simple and easy to use UI. You can see UI elements only when you need them.

There is a pull-down panel with thumbnails, as well as folder view (accessible by pressing Return).

You can also bring up a context menu by right-clicking an image.

Using quick copy / quick move panels

Bring up the panel with C or M shortcut. You will see 9 destination directories, click them to set them up.

With panel visible, use 1 - 9 keys to copy/move current image to corresponding directory.

When you are done press C or M again to hide the panel.

Running scripts

You can run custom scripts on a current image.

Open Settings > Scripts. Press Add. Here you can choose between a shell command and a shell script.

Example of a command:

convert %file% %file%_.pdf

Example of a shell script file: ```


gimp "$1" ``` Note: The $1 argument will be a full file path. Also, the script file must be an executable.

When you've created your script go to Settings > Controls > Add, then select it and assign a shortcut like for any regular action.


If qimgv appears too small / too big on your display, you can override the scale factor. Example:

QT_SCALE_FACTOR="1.5" qimgv /path/to/image.png
You can put it in
file to make it permanent. Using values less than
may break some things.

qimgv should also obey the global scale factor set in KDE's systemsettings.

High quality scaling

qimgv supports nicer scaling filters when compiled with

support (ON by default, might vary depending on your distribution). Filter options are available in Settings > Scaling.

Possible build issues

  • If you get errors like "/usr/lib64 exists in filesystem" during install:


to cmake command.
  • If you get some errors like "std::filesystem not found":

qimgv needs a compiler with c++17 support - for example gcc 8.0+ (every recent distro has it)

If you have multiple version of gcc installed you might need to specify a which version for

to use, for example

CC=gcc-8 CXX=g++-8 cmake [........]
