New Functionality

Adobe Reader XI provides full commenting capabilities, including text, stamps, file attachments and audio recordings, as well as drawing markups, like lines, arrows, shapes and free-form annotations. Do you have a PDF form that needs attention? Well, Reader is now able to fill, sign, save and send your forms without requiring printing and mailing. And, of course, you can do this on the most recent and popular operating systems, OS X Mountain Lion and Windows 8, which includes our new “touch-mode” for an optimal tablet experience.

Mobile and the Cloud

Wherever you are, save your PDFs to Acrobat.com for access from anywhere, including your mobile devices via Adobe Reader for Android and iOS. Also, leverage Adobe Reader XI’s integration with our cloud services, including creating PDF, exporting PDF files to Word and Excel, or sending your documents for signatures and full tracking via Adobe EchoSign.


We really moved the needle with Protected Mode in Adobe Reader X. Now, we’ve enhanced Protected Mode in Adobe Reader XI to include data theft prevention capabilities. We’ve even added a new Protected View, which implements a separate desktop and winstation for the UI, providing an additional layer of defense. For high-risk environments, we’ve added the PDF Whitelisting Framework, which allows the selective enablement of JavaScript for both Windows and Mac OS, including support for certified documents. And, in the area of content security, we’ve expanded our support to elliptic curve cryptography.

Enterprise Deployment

We spent a lot of time with our Citrix XenApp support, and especially focused on performance, which is key when accessing Adobe Reader XI from your tablet devices. Also, if you’re rolling out application streaming, we’re now supporting Microsoft App-V, including a Package Accelerator. Need a GPO template? We’ve added that to this release too! And, of course, we continue to enhance our support for Microsoft SCCM/SCUP, Apple Remote Desktop and have even added a Configuration Wizard for the Mac. For all your enterprise questions, checkout our new Enterprise Toolkit.

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.[20] Additional, 'Premium', services are available for reader on paid subscription. The commercialproprietary 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.

  • 2Internationalization and localization
  • 3Security


Adobe Acrobat came to being in 1993 and had to compete with other products and proprietary formats that aimed to create digital documents:

  • Common Ground from No Hands Software Inc.[21]
  • Envoy from WordPerfect Corporation
  • Folio Views from NextPage
  • Replica from Farallon Computing[22]
  • WorldView from Interleaf[23]
  • DjVu from AT&T Laboratories

Adobe allows third parties to develop Acrobat plug-ins, which can add extra functions to the Acrobat program.

Acrobat XI
Reader XI
Distiller XI

Adobe has renamed the Acrobat products several times, in addition to merging, splitting and discontinuing them. Initially, the offered products were called Acrobat Reader, Acrobat Exchange and Acrobat Distiller. 'Acrobat Exchange' soon became 'Acrobat'. Over time, 'Acrobat Reader' became 'Reader'. Between versions 3 and 5, Acrobat did not have several editions. In 1999, the Acrobat.com service came to being and introduced several web services whose names started with 'Acrobat', but eventually, 'Acrobat.com' was downgraded from the name of the family of services, to that of one those service.

By 1 April 2015, the Acrobat family consisted of:[24]

  • Acrobat XI Pro (for Windows and macOS)
  • Acrobat XI Standard (for Windows only)
  • Reader XI (for Windows, macOS, Android and iOS)
  • FormsCentral (web service with desktop client)
  • EchoSign (web service)
  • Acrobat.com (web service)
  • PDF Pack (web service)
  • Send (web service)

Unlike most other Adobe products, such as members of Adobe Creative Suite family, the Acrobat products do not have icons that display two letters on a colored rectangle.

Document Cloud[edit]

In April 2015, Adobe introduced the 'Document Cloud' branding (alongside its Creative Cloud) to signify its adoption of the cloud storage and the software as a service model. Apps under this branding received a 'DC' suffix. In addition, 'Reader' was renamed back to 'Acrobat Reader'.[25][26] Following the introduction of Document Cloud, Acrobat.com was discontinued as their features were integrated into the desktop and mobile apps.

The UI had major changes with the introduction of Acrobat DC in 2015, which supports Windows 7 and later, and OS X 10.9 and later. Version numbers are now identified by the last two digits of the year of major release, and the month and year is specified; the previous version was 12, but examples of the DC (Document Cloud) Acrobat product family versions are DC June 2016, version 15.016.20045, released 2 June 2016 and DC Classic January 2016, version 15.006.30119, released 12 January 2016.[27] From DC 2015 the Acrobat family is available in two tracks, the original track, now named Classic, and the Continuous track.[28] Updates for the Classic track are released quarterly, and do not include new features, whereas updates for the Continuous track are issued more frequently, and implemented silently and automatically.[29]

The last pre-DC version, Acrobat XI, was updated to 11.0.23 version (and this was the final release[30]) on November 14, 2017,[31] support for which ended on October 15, 2017.[32]

As of August 2018, the main members of the Acrobat family include:[33]Running man streaming indo.

  • Acrobat Pro DC (for Windows and macOS)
  • Acrobat Standard DC (for Windows only)
  • Acrobat Reader DC (for Windows, macOS, Android, iOS and Windows Phone)
  • Fill & Sign (for Android or iOS)

  • Scan (for Android or iOS)

Internationalization and localization[edit]

Language availability[edit]

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,[34]Adobe Systems' internationalization and localization partner.

Specific features for Arabic and Hebrew languages[edit]

The Arabic and Hebrew versions are 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.


A comprehensive list of security bulletins for most Adobe products and related versions is published on their Security bulletins and advisories page and in other related venues.[35][36] In particular, the detailed history of security updates for all versions of Adobe Acrobat has been made public.[37]

From Version 3.02 onwards, Acrobat Reader has included support for JavaScript. This functionality allows a PDF document creator to include code which executes when the document is read. Malicious PDF files that attempt to attack security vulnerabilities can be attached to links on web pages or distributed as email attachments. While JavaScript is designed without direct access to the file system to make it 'safe', vulnerabilities have been reported for abuses such as distributing malicious code by Acrobat programs.[38] Adobe applications had already become the most popular client-software targets for attackers during the last quarter of 2009.[39]McAfee predicted that Adobe software, especially Reader and Flash, would be the primary target for software attacks in the year 2010.[40]

September 2006 warning[edit]

On September 13, 2006, David Kierznowski provided sample PDF files illustrating JavaScript vulnerabilities. Since at least version 6, JavaScript can be disabled using the preferences menu[41] and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from activating.[42]

February 2009 warning[edit]

On February 19, 2009, Adobe released a Security Bulletin announcing JavaScript vulnerabilities in Adobe Reader and Acrobat versions 9 and earlier.[43] As a workaround for this issue, US-CERT recommended disabling JavaScript in the affected Adobe products, canceling integration with Windows shell and web browsers (while carrying out an extended version of de-integration for Internet Explorer), deactivating Adobe indexing services and avoiding all PDF files from external sources.[44]

February 2013 warning[edit]

Adobe has identified critical vulnerabilities in Adobe Reader and Acrobat XI (11.0.01 and earlier) for Windows and Macintosh, 9.5.3 and earlier 9.x versions. These vulnerabilities could cause the application to crash and potentially allow an attacker to take control of the affected system. There have been reports of these vulnerabilities being exploited to trick Windows users into clicking on a malicious PDF file delivered in an email message. Adobe recommended users update their product installations.[45]

January 2016 warning[edit]

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.[46][47]
