Check out our video on “Using the object inspector to examine page objects”: [https://youtu.be/IZIhyM3WFMQ](https://youtu.be/IZIhyM3WFMQ).

With the object inspector in pdfToolbox Desktop, you can examine all the page objects in your PDF.

But that’s not all! You can also use it to derive preflight checks based on the object properties provided by the inspector. This makes it easier and faster to set up complex checks for specific elements.

This video shows you how to use the object inspector to generate preflight checks directly from selected page objects.
