* Browser Based PDF Viewing and Editing. activePDF Portal can be hosted entirely on your server and enables your users to interactively view and modify PDF documents from any source - adding comments, form fields, bookmarks, and more – directly from within a standard web browser, without requiring any client-side software such as Adobe Reader or Flash, or the use of ActiveX controls. With activePDF Portal, you can selectively disable the end user’s PDF editing, printing and saving capabilities, allowing for full protection against unauthorized distribution or tampering.
