The Batch Queue Manager tools are available as plugins loaded dynamically at startup and configurable in Setup dialog. Except few ones, mostly all tools share the same functionalities than plugins from Image Editor. The difference with Image Editor tools is that there is no possibility to preview the tool effects over the images. Other tools are more designed to Convert to file formats, and to apply the Digital Asset Management.
These tools allow to save images to new file formats. These are mostly placed at end of your list of Assigned Tools from your Workflow.
