Acrobat is a suite of productivity applications developed and distributed by Adobe Systems. Adobe Acrobat (full version) enables the user to edit, modify, secure and manage Portable Document Format (PDF) documents. In addition, Adobe Acrobat will allow the user to remove password security and encryption from a secured PDF file. To unsecure a PDF file, the user must use the editing password. Obtain the PDF editing password from the owner or creator of the PDF document. Once the password has been entered, and the steps performed, password protection and security may be completely removed from the document.
