**About Ghostscript** : I use this version : [github.com/ArtifexSoftware/ghostpdl-downloads/releases/tag/gs10050](https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/tag/gs10050)

Right click on on the square

From the contextual menu you can choose the output folder.

## Avanced configuration

`base_args` value is a list with Ghostscript default parameters for all profiles.


Then you'll find `high`, `medium` and `low` profiles parameters. Each one have custom [Ghostscript parameters](https://ghostscript.readthedocs.io/en/latest/index.html).
