How to remove password protection from PDF file save without password



I have a password protected pdf document. I can open it because I know the password. But in some cases peoples need to save it without password. Is it possible to save a copy without password?
So is there another way?
Answer - Yes,
Advanced PDF Password Remover is a small and easy-to-use tool to decrypt protected Adobe Acrobat PDF files, which have "owner" password set, preventing the file from editing, changing, printing, selecting text and graphics and copying them into the Clipboard, or adding/changing annotations and form fields.  Also It can remove the user/open password which protects the PDF files from opening if you know the password. Decryption is being done instantly. Decrypted files can be opened in any PDF viewer without any restrictions. All versions of Adobe Acrobat (including 9.x, which features 128-bit encryption) are supported.
