I need to resize a pdf file to crop its surrounding white border. I can crop it using PDF-Shuffler on Ubuntu. But cant save the change, because of owner password protection. When i try to open that file using PDF-Editor, it asked for that password.
Since I dont know that owner password, so cant use regular recovery system. There are lots of online system too, but thats very slow process even most of those cant remove owner password. Now looking for a script/software specially for Ubuntu to remove that owner password.
