Adobe Acrobat is a family of application software and web services developed by Adobe Systems to view, create, manipulate, print and manage files in Portable Document Format (PDF).[15]

The family comprises Reader (formerly Acrobat Reader), Acrobat (formerly Acrobat Exchange) and Acrobat.com. The freeware Adobe Reader, available for several desktop and mobile platforms, can view, print and annotate PDF files.[16] The commercial proprietary Acrobat, available for Windows and OS X 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.

History[edit]

Since the early 1990s, the Acrobat product has had several competitors, some of which used their own document formats, such as:

By the late 1990s PDF had become the de facto standard. This has resulted in the development of both free and commercial programs that create or manipulate PDF. Adobe also allows Acrobat plug-ins to be developed by third parties, which can add extra functions to the Acrobat program.

Product names[edit]

Adobe has changed the names of the products of the Acrobat set regularly, also dividing, merging, or discontinuing products. Initially, the name "Acrobat" was used as the parent name of a set of products which included Acrobat Reader, Acrobat Exchange and Acrobat Distiller. Over time Acrobat Reader became Reader; and the name Acrobat Exchange was simplified to Acrobat. Between version 3 and 5, Standard and Professional versions were one product known simply as Acrobat.

As of March 2013, the current main members of the Acrobat family are:[17]

Acrobat[edit]

Version 1.0[edit]

Acrobat 1.0 was released originally on 15 June 1993 for Macintosh computers. It was released later for the operating systems DOS and Windows 3.1. This was not available as single copies and was not initially free, with Acrobat Reader priced originally at $50 per user.[18] After a while, the Internal Revenue Service of the United States purchased a right to distribute the program Reader 1.0, effectively making it seem free to those who obtained it that way.

Adobe Acrobat 1.0 included:

  • Support for PDF version 1.0
  • Acrobat Exchange 1.0 (included PDFWriter printer driver and Acrobat Exchange application)
  • Acrobat Distiller 1.0, a software application that creates a PDF file from a PostScript source

Version 2.0[edit]

Acrobat 2.0 was first released during September 1994 for the operating systems Windows and Macintosh. It included:

  • Support for PDF version 1.1
  • Acrobat Exchange 2.0
  • Acrobat Catalog, which creates searchable indexes for PDF files

Acrobat Professional 2.0 was also released, which included Acrobat Exchange plus the program Distiller.

Adobe also released the first Acrobat Plug-ins SDK; allowing third party developers to create plug-in programs for the Acrobat Exchange application.

Version 3.0[edit]

Acrobat 3.0 was released during November 1996. It was the first release usable with Windows 95, and the last to be usable with Windows 3.1. It was also the first version to display PDF files inside web browsers, and the first to have form-filling functions. Later, an update to version 3.02 introduced extended forms capabilities and JavaScript. Adobe Acrobat 3.0 included:

  • Support for PDF version 1.2
  • A free Reader that allows searching (It was not part of the default copy)
  • Acrobat Catalog
  • A Distiller printer driver

Version 4.0[edit]

Acrobat 4.0 was released during April 1999. It included:

Distiller Server 4.0, and Acrobat Business Tools 4.0 were also released at this time. Distiller Server was a version of Distiller for Windows, Linux and Solaris that is licensed to multiple users. Acrobat Business Tools was a limited[clarification needed] version of Acrobat.

Version 5.0[edit]

Acrobat 5.0 was released in May 2001. It included support for PDF version 1.4 and was the last version to be usable with Windows 95. Acrobat 5.0.5 was the first to be able to operative native in Mac OS X, but also operated in Mac OS 9.

This version did not include PDFWriter with the Macintosh release.[19]

Acrobat Reader 5.1, the subsequent version of Acrobat Reader usable with the Adobe LiveCycle Reader Extensions for forms saving.

Adobe also released Distiller Server 5.0 and Acrobat Approval 5.0, a limited version of Acrobat mainly sold to people who wanted to digitally sign PDF files or save fill-in forms.

Version 6.0[edit]

Acrobat 6.0 was released during July 2003. This version introduced significant changes to the set of Adobe Acrobat:

  • Adobe Acrobat Standard 6.0 was released. It is a limited version of Acrobat Professional that includes Distiller but lacks Adobe Catalog, form design features and pre-press support.
  • Adobe Acrobat Elements 6.0 was introduced. It enabled PDF creation but was intended for the corporate market and was only volume-licensed for a minimum of 1000 licenses. It was available for Microsoft Windows only.
  • Acrobat Elements Server 6.0, a server software version of Acrobat Elements, was introduced.
  • Adobe Acrobat Reader was renamed Adobe Reader.
  • Distiller printer driver was renamed Adobe PDF.
  • PDFWriter, a printer driver used to create PDF files, was discontinued in favor of the Adobe PDF printer driver to Distiller.
  • A new version of Adobe Catalog was included, which was not compatible with earlier products for searching.
  • Support for many operating systems was ended. Mac OS 9 was no longer compatible. No version of Adobe Acrobat for Linux or Unix was released. Adobe Acrobat Standard was not compatible with Windows 95 and Windows 98, although it was usable with Windows 98 SE. Adobe Acrobat Professional ceased to be compatible with Windows 95, Windows 98 and Windows Me.

This version included:

  • Support for PDF version 1.5
  • Support for PKI (without a plug-in) via Microsoft CryptoAPI
  • Support for "Reader enabling", allowing Adobe Reader to save, sign or annotate PDF files if the PDF file allowed

Version 6 was criticized for its performance. Adobe Acrobat 6 is slow to load and use. The Acrobat 6 plug-ins for web browsers were also criticized for suffering from bad performance and potentially rendering one's web browser non-responsive.[20]

Version 7.0[edit]

Adobe Acrobat 7.0 was released during January 2005:[21] It was the first version to include a mandatory product activation. It included:

  • Support for PDF version 1.6
  • Support for Adobe Policy Server rights management
  • Support for embedded 3D object information from the .u3d Universal 3D format

The Adobe Acrobat 7 set experienced multiple changes. Adobe Acrobat 7 Professional for Windows now included Adobe LiveCycle Designer 7.0. Adobe Elements 7.0 was also released which was still only sold by volume licensing outlets but decreased the minimum licenses limit to 100 licenses. Finally, another edition of Adobe Acrobat, Acrobat 3D, was added to the set.

Adobe Acrobat 3D included all of the functionality of Acrobat Professional 7.0 as well as updated assistance for embedded 3D computer graphics, tools for capturing 3D content from OpenGL applications, and the Adobe Acrobat 3D Toolkit for converting CAD documents to PDF objects. Also included is a version of the capture tool for installation on Unix systems.

Acrobat 7 ended support for Windows 98 Second Edition and Windows Me. However, Adobe released editions of Adobe Reader for Linux, Solaris (SPARC only), HP-UX and IBM AIX.

Version 8.0[edit]

Adobe Reader 8 operating on Windows Vista

Adobe Acrobat 8.0 was released during November 2006.[22] It included:

  • Support for PDF version 1.7
  • Acrobat 8 Elements, which was withdrawn before its expected release during mid-2007[23]
  • Acrobat Connect (formerly Macromedia Breeze), a support application with online personal meeting rooms to collaborate in real time with as many as 15 participants

A later update 8.1 on June 2007 was released in order to be compatible with Microsoft Office 2007, Windows Vista, and 64-bit Windows operating systems.[24] Also during September 2007, Adobe Reader 8.1.1 released for Linux and Solaris (SPARC) users.

The Adobe Acrobat 8 set had a few changes. Acrobat 3D was now able to produce embedded PRC file format, a very compressed format for geometry and graphics which requires Reader 8.1 to display. It also supported Product Manufacturing Information and many different CAD formats.

Acrobat Connect Professional (formerly Macromedia Breeze) was also added to the set. It allowed scalable interactive web conferencing and multiple personal meeting rooms for everyone part of an enterprise.

The Mac OS X version of Adobe Acrobat Pro was improved significantly: Adobe Acrobat for Macintosh was made a Universal binary that operated on both PPC and Intel architectures.

8.x product support ended in November 2011.[25]

Version 9.0[edit]

Adobe Acrobat 9.0 was released June 2, 2008.[26][27] Support for version 9 ended June 26, 2013,[28] with the last available update being 9.5.5. This version included:

  • Support for PDF version 1.7
  • Support for Adobe extensions for PDF 1.7
  • The ability to create Acrobat forms was in Acrobat Standard, which was previously only available with Acrobat Professional 6, 7 and 8
  • Support for real-time collaboration on PDF files with synchronized document views and chat
  • Improved Web Capture for copying entire web pages or just some parts into PDF

  • Support for comparing and highlighting the differences between two versions of a PDF document
  • Support for playback of Flash Video or H.264 video in Adobe Acrobat and Adobe Reader
  • Support for conversion of a variety of[which?] video formats to Flash Video for playback inside PDF
  • Support for creating PDF maps by importing geospatial files that retain metadata and coordinates
  • Support for Optical character recognition (OCR) on PDF files using ClearScan. Adobe ClearScan technology creates and embeds custom Type1-CID fonts to match the visual appearance of a scanned document after optical character recognition. ClearScan uses these newly created custom fonts instead of system fonts or Type1-MM

The Adobe Acrobat 9 set includes a new program: Adobe Acrobat 9 Pro Extended for Microsoft Windows. This product includes Adobe Presenter as well as the features of Acrobat 3D.

Adobe Reader 9 ends compatibility with Adobe Reader Extensions 5 and 6 which permit Adobe Reader client software to save changes to filled-in forms in PDFs. Adobe Reader Extensions 6.1 and newer are still usable. Legacy PDFs will still be viewable, however they will open with the warning "This document enables Reader capabilities that are no longer enabled in this Reader version."[29]

The Adobe Acrobat 9 set also omitted the multiple document interface. Previous versions of Adobe Acrobat activated multiple PDF files in the same window. Acrobat 9 however, only uses the single document interface scheme, wherein each PDF file is activated in an instance of Adobe Acrobat.[30]

Version 10.0[edit]

Adobe Acrobat X (version 10.0) was released on November 15, 2010.[31][32] This version is supported by Adobe until November 15, 2015. It included "sandboxing" protection for Windows XP, Windows Vista and Windows 7. Compatibility was ended for Windows 2000 and Power PC based Apple Macintosh computers.

Adobe Reader X is available for Windows, Mac OS, Android, and iOS.[33][34][35][36] Compatibility with Linux is not planned.[37]

Version 11.0[edit]

Adobe Acrobat XI (version 11.0) was announced on October 1, 2012.[38] This version is supported by Adobe until October 15, 2017. The graphical user interface for desktop systems is carried over from version 10. Some new features include a completely redesigned PDF editing experience, exporting PDF files to Microsoft PowerPoint, touch-friendly capabilities for mobile devices, and integrated cloud services. LiveCycle Designer is no longer bundled (but remains a standalone product). Acrobat XI was released to the market on October 15, 2012.

Adobe Acrobat XI is available for Windows XP, Windows 7 and Windows 8, but not Windows Vista. It is also available for Mac OS X Snow Leopard or later.[35]

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,[46] 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.

Security[edit]

The latest security bulletins from Adobe are published on their Security bulletins and advisories page.[47] There have been security updates for Adobe Reader and Acrobat on January 10, April 10 and August 14, 2012, and January 8, 2013.[48]

From Version 3.02 onwards, Acrobat Reader (now Adobe 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.[49] Adobe applications had already become the most popular client-software targets for attackers during the last quarter of 2009.[50] McAfee predicted that Adobe software, especially Reader and Flash, would be the primary target for software attacks during 2010.[51]

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 and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from activating.[52]

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.[53] 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 service and avoiding all PDF files from external sources.[54]
