PDF files are considered to be the most secure form of documentation because of the various features offered by the format. These documents can be protected by passwords, encryption techniques and local restrictions so that the data is not accessed by everyone. All these methods make PDF files apt for sharing over the Internet without the fear of getting tampered. This is also necessary as PDF file formats are most commonly used as e-books, white papers, datasheets, manuals, etc. While encryptions disable the search engines to access the metadata of the files, local restrictions make the files non-editable. However, users are often unable to access data they require when the documents are in PDF format and protected. To freely access PDF content, it is essential to first unprotect PDF files and remove the imposed restrictions from them. But, this can only be done by document authors who have put the restrictions and password protected the files.
For users who do not have the security password and access to the security settings of the files, it is difficult to unprotect PDF files to use them in any form. Removing protection from PDF files also become important for document authors sometimes when they lose their file passwords. In such a situation the files cannot be opened and desired changes cannot be made to the documents. Therefore, to resolve such issues, PDF restriction removal tools must be used.
