Adobe Acrobat 7 Professional allows business professionals to reliably create, combine, and control Adobe PDF documents. This comprehensive suit of powerful tools allows you to create PDF files with the click of a button from Microsoft applications and AutoCAD and easily attach source documents such as spreadsheets, multimedia files, images, and drawings to an Adobe PDF document that is easy to share with others using free Adobe Reader software. The best thing this program has to offer are its security options that ensure that your confidential data and documents do not end up in the wrong hands. For instance, you can apply digital signatures that can be authenticated and also passwords and permissions to control who can open, view, edit, and print a PDF document. Unfortunately, downloading the trial version of the program takes more time than it usually takes to download any trial, since you must register and fill out a survey at Adobe's Web site and then, you must wait for an e-mail to arrive with a link to the installer. So, If you're an occasional PDF creator,do not waste time and effort downloading this trial.
