Adobe Acrobat

Adobe Acrobat is a software package first released by Adobe Systems on June 1993 for Macintosh Computers. Adobe Acrobat is a collection of applications and web services that enables users to create, edit, view, and print PDF files. PDF stands for Portable Document Format, a document format unique to the Adobe systems.

Adobe Acrobat is divided into three sections—Acrobat Reader, Acrobat, and Acrobat.com. Acrobat Reader enables users to view and print PDF files. Users may even add annotations in the form of comments, highlights, underscores, and strikeouts on the PDF document. Acrobat Reader is a freeware and may be downloaded separate from the Adobe Acrobat. Acrobat is a proprietary software with the same capabilities as Reader, but with additional functions. These include PDF conversion and encryption. Users may also publish, export, and digitally sign PDF documents. Lastly, Acrobat.com takes care of the online service functions of Adobe. It includes PDF file hosting services, as well as enterprise content management functions. These functions are CreatePDF,  ExportPDF, EchoSign, and FormsCentral. Other web hosting functions include SendNow, Personal Storage, and Workspaces.

Adobe Acrobat is primarily developed for desktop computers. However, on November 2010, Adobe Reader was released for mobile and handheld devices as Adobe Reader X. Adobe Systems also released the Adobe Reader Touch especially developed for Windows Tablets supporting the modern Windows 8 UI on December 2012.
