How to Make a PDF Editable in Adobe Acrobat Pro
Depending on the material contained in a PDF you may need to make it editable for other users. For example, you may need to distribute a PDF form to collect information. You may also need another user to have the ability to edit PDF content without the source file being available. You can make a PDF editable in Adobe Acrobat Pro by enabling the user rights.
Launch Adobe Acrobat and open the PDF file for which you want to enable editing. Note that the following steps will work with all versions of Adobe Acrobat (Standard, Pro and Suite).
Click the "Forms" menu and select the "Close Form Editing" option. If you are not editing a PDF form in Acrobat, skip to step three.
Click the "File" menu and select the "Save As" option to display a list of available options. Highlight the "Reader Extended PDF" option and click the "Enable Additional Features" option to enable editing of the PDF.
