I am using Adobe Acrobat Pro from past few months, I have some PDF documents that need to combine on an urgent basis. Whenever I tried to combine PDF files I was encountered with the error message “The file is protected it cannot be used for this command”. I don’t know why I am getting this error message. Can anyone tell me how to resolve this issue so that I combine PDF files easily?
This type of error message generally occurs when the file is having restrictions. It might be possible that the PDF document is secured by someone due to which you are unable to combine them. Therefore, I would suggest you to firstly remove file security after that combine PDF files.
Yes, of course, you need to go through these steps:
1- Firstly, open Adobe Acrobat Pro application
2- Then, open the secured PDF document if any password then enter it
3- Click on the File option & then Properties
4- Select the Security tab and choose No Security to remove security completely
5- After that save the file without having any restrictions
No need to worry if you don’t have Adobe Acrobat. I know it is a very expensive utility which cannot be easily afforded by normal Adobe users. So, you can opt for SysTools PDF Unlocker tool, this software can easily remove protection from PDF document. Once, you remove the security file can be easily combined.
Also, for merging the documents you can use SysTools PDF Split & Merge software. This software can join multiple PDF documents at once. It does not have any file size and number limitations.
