Pdf – How to make a PDF readonly without password

copy protectionpdf

I have no Acrobat and need to make users access the PDF without using password, but prevent them from copying the PDF(the file itself and the content).

I tried many online PDF LOCKER things, but it can't restrict copying the PDF.

I wish downloading Acrobat free trial is not the only option.

The short answer is you can't actually prevent a PDF from being copied or modified. Adobe software might follow the rules but other programs might not.

If you want to let people see the content of your PDF they will be able to do what they want with it if they try enough. Many PDF readers for example ignore the "no printing" flag.
