Extended: Can I Remove Password from PDF on Mac with Terminal or Adobe Reader?

#1 Can I Remove Password from PDF with Mac Terminal

Maybe, but you are not recommended to do so.

Actually, I tried the steps on Internet to remove password from PDF with Mac Terminal. It requires you to install qpdf and brew to run the command lines. I installed the both tools, but when running commands, it requires me to install another tool called X-code to run the lines. And then I get repeated error message in Mac Terminal. So, I quit.
Even if you have make the command lines run well, it is far too complicated to remove a password from PDF with Terminal, it is just not necessary to do so.

#2 Can I Remove Password from PDF with Adobe Reader for Mac?

No, you can not, you have to subscribe Adobe Acrobat to use its Protect tool.

Adobe Acrobat Reader can only open, view, bookmark, print, annotate your PDF files, you can enter PDF password to view or print the file, but you cannot remove the security settings without buying Adobe Acrobat.


There may be more option to remove pdf password protection on a mac, but the most efficient way is always turning to an expert. And for this reason, I recommend you to invest in a third-party app like Cisdem PDF Password Remover for Mac to remove the PDF password.

    I tried online tools at the beginning, but went nowhere. It seems that offline programs are the best way out, they allow to remove both user and permission password.
