The difference between adding read-only password and no password to PDF documents, as well as the advantages and disadvantages

1. PDF files are added with a read-only password that cannot be modified at will. Although we can open and read the contents of PDF files, there is no way to modify, copy, print and extract text from files. This setting can be used to protect the integrity and copyright of documents on special occasions or for some organizations. Read-only password allows people who do not know the password to restrict the operation and can only view it, ensuring that the contents of the document will not be accidentally deleted or maliciously modified, and protecting the professionalism of PDF document format. However, this approach may cause a lot of inconvenience to team collaboration or frequent processing of document content.
2. However, PDF documents can be modified at will without a read-only password, which allows users to edit, copy and print freely. It is very convenient to use when documents need to be shared, especially the operation of some non-sensitive information on dissemination and modification. Files that do not have a read-only password will be more flexible, which is convenient for users to modify and copy content in various situations and improve work efficiency. However, this open document model is also accompanied by potential risks, such as being arbitrarily modified and used improperly, which greatly reduces security.

Summary

Batch deletion of PDF read-only passwords, from team collaboration to academic research, from educational scenes to enterprise files, is like being unlocked in all walks of life. As long as read-only passwords are deleted, modification, copying and printing are all out of the question. All the operating tools introduced above are the first method. It is not only fast and full-featured, but also friendly to newcomers and Xiaobai, and pays more attention to privacy. I believe that after looking at the advantages and disadvantages of the previous tools, everyone can find the right choice. Of course, remember to back up the original file when using it, develop good habits, and avoid data loss due to operational errors. Finally, I would like to remind you that although the tool for deleting secrets is good, the original copyright should also be respected! If it is your own file, remember to reset the security password after deleting the secret protection. If it is someone else's file, be sure to obtain authorization before operating. After all, honesty and safety are the most important things when it comes to efficiency. Now, try these tools!
