Topic: Compare two PDF files

I want to check whether two PDF files look like the same by program. (Suppose the byte stored in these two PDF files are different, so compare byte by byte must fail).
Is the most effective method is to "print" it and compare them pixel by pixel, just like the Compare function of Acrobat?
Or I can try to transform these two PDF files to some common simple form? (e.g. the form without any optimization or encryption)
Please give my some advices, thank you.
