Adobe Acrobat : Application Software and Web services

Software Knowledge : Adobe Acrobat is a family of application software and Web services developed by Adobe Inc. to view, create, manipulate, print and manage files in Portable Document Format (PDF).

The family comprises Acrobat Reader (formerly Reader), Acrobat (formerly Exchange) and Acrobat.com. The basic Acrobat Reader, available for several desktop and mobile platforms, is freeware; it supports viewing, printing and annotating of PDF files.

Key Points :

Additional, "Premium", services are available for reader on paid subscription. The commercial proprietary Acrobat, available for Microsoft Windows and macOS only, can also create, edit, convert, digitally sign, encrypt, export and publish PDF files. Acrobat.com complements the family with a variety of enterprise content management and file hosting services.

The main function of Adobe Acrobat is creating, viewing, and editing PDF documents. It can import popular document and image formats and save them as PDF.

It is also possible to import a scanner's output, a website, or the contents of the Windows clipboard. Because of the nature of the PDF, however, once a PDF document is created, its natural organization and flow cannot be meaningfully modified.

In other words, Adobe Acrobat is able to modify the contents of paragraphs and images, but doing so does not re-paginate the whole document to accommodate for a longer or shorter document. Acrobat can crop PDF pages, change their order, manipulate hyperlinks, digitally sign a PDF file, add comments, redact certain parts of the PDF file, and ensure its adherence to such standards as PDF/A.

Adobe has released security updates for Adobe Acrobat and Reader for Windows and Macintosh. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

Adobe Acrobat is available in the following languages: Arabic, Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Turkish and Ukrainian.

Arabic and Hebrew versions are available from WinSoft International,[35] Adobe Systems' internationalization and localization partner. Before Adobe Acrobat DC, separate Arabic and Hebrew versions were developed specifically for these languages, which are normally written right-to-left. These versions include special TouchUp properties to manage digits, ligatures option and paragraph direction in right-to-left Middle Eastern scripts such as Arabic, Hebrew, and Persian, as well as standard left-to-right Indian scripts such as Devanagari and Gujarati.

The Web Capture feature can convert single web pages or entire web sites into PDF files, while preserving the content's original text encoding. Acrobat can also copy Arabic and Hebrew text to the system clipboard in its original encoding; if the target application is also compatible with the text encoding, then the text will appear in the correct script.
