What you get
The removal cannot be undone
Nothing in the finished file can bring the marked content back. Your original file is not touched, so keep it until you have opened the result and checked it.Each page you mark is rebuilt without the content inside your areas, so there is no black box to lift off. Text you did not mark is laid back over the page and stays searchable.
The finished file is decompressed and searched for every word above. If one is still there you get an error instead of a file.
