ID Util

ID Util is a free and interesting utility from Markzware, available for Mac Users directly in the App Store.

Drag-and-drop InDesign files onto the utilities window and immediately get some infos about the file. Documents can be previewed, printed and exported – as far as some settings for previews in the documents have been set beforehand. ID Util works without the need to run a full version of InDesign.
