If the How to adjust file format options export option is set to Interactively, and you press the Export button, it may seem as though nothing happens. In that case, the file format dialog may be displayed behind GIMP. If so, select the dialog in the taskbar to bring it up.

For Batch Convert, import options for unrecognized file formats cannot be adjusted and default values will be used.

Images created by custom actions (e.g. via plug-in-decompose) are currently not usable in Batcher. This will be resolved in a future version.
