This program will just save the loaded pdf without any changes. As PDFBox doesn't support writing compressed object streams those streams are stripped and will be gone in the resulting file. This is very helpful when trying to debug problems as it'll make it possible to easily look through a PDF using a text editor. It also exposes problems which stem from objects inside object streams overwriting other objects.
