How to get pdf passwords off

Does anybody know how to get adobe password protection off pdf’s?

There are some tools available on the web, not all that effective. It depends also on the version of the file, newer versions have a better encryption. You have to be careful with many of those tools too, they might be used by others who do not have honorable intentions (may include spyware, malware, etc.).

Not much, but I hope it helps anyway
