Convert Jar file to EXE executable.

[ad name=”AD_INBETWEEN_POST”] I remember the day when I created a Tic Tac Toe game using Java Swing and packed it in an executable JAR file to distribute it among my friends. As few of my friends were not from computer background, they were unable to execute the JAR file. Hence I converted the JAR into EXE and send them the EXE.

It is sometime desirable to convert the JAR file in to EXE (executable) and distribute the EXE. Although the exe can be executed only in Windows environment, this will definitely affects the “platform independency” of a Java program. Still if you want to convert a JAR file in EXE then following tools are for you.

JSmooth .exe wrapper

java jar file to exe executable JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a web site.

JSmooth provides a variety of wrappers for your java application, each of them having their own behaviour: Choose your flavour!


JarToExe 1.8

Jar2Exe is a tool to convert jar files into exe files.
Following are the main features as describe in their website:

  • Can generate “Console”, “Windows GUI”, “Windows Service” three types of exe files.
  • Generated exe files can add program icons and version information.
  • Generated exe files can encrypt and protect java programs, no temporary files will be generated when program runs.
  • Generated exe files provide system tray icon support.
  • Generated exe files provide record system event log support.
  • Generated windows service exe files are able to install/uninstall itself, and support service pause/continue.
  • New release of x64 version, can create 64 bits executives. (May 18, 2008)
  • Both wizard mode and command line mode supported. (May 18, 2008)



Package your Java application as a jar, and Executor will turn the jar into a Windows exe file, indistinguishable from a native application. Simply double-clicking the exe file will invoke the Java Runtime Environment and launch your application.

Advanced Installer lets you create Windows MSI installs in minutes. This also has Windows Vista support and also helps to create MSI packages in other languages.

    You can also try Launch4j that is opensource and hosted on Sourceforge.

  2. Alex van Beek says:

    Can generate multi platform wrappers.

    • Launch4j is very good, but it has two disadvantages:
      Its generated .exe file can be extracted (e.g. by winrar)
      Doesn’t support passing variable parameters (e.g. file name)

      However, it is suitable for most applications that don’t receive parameters

      • @Osama – Thanks for sharing your findings with Launch4j.. Very useful for users..

    very nice thanks , i didn\’t knew these application do exist :)

    Nice post… Can we change the icon of the exe file using any of the above tools?

    • Ferrybig says:

      you can do this whit the limited time of the Jar2Exe Wizard 1.8 tool

  11. Sunish VK says:

    I have tried most of the tools mentioned above. I found Inno Setup as the best tool for creating Setup exe files. That allows you to add icon for exe and also uninstallation support also there.

  12. DJ says:

    Thank You So Much! copacetic!!!

  13. waddah says:

    those r some vwey nice tools yet the problem persists in the fact that you need a JRE to start the exe files u created using these converters and its not always that easy for end users to install u know of any program that converts jar into exe files that dont require a JRE environement to run at all?

    • Nepster says:

      Java can not run without JRE.

      However, if not installed, it should prompt to download and install automatically.

  14. @waddah, I understand it is not common that people install JRE on their system. But I am not aware of any way of running a JAR file without JRE!! This may not be good solution but you may want to make a prerequisite of installing a JRE before installing your Java software.

  15. suggestive conclusion… wehehehe…. don’t try all just pick your most trusty p2p servers like mine….

  16. gilles says:

    And is it possible to reverse again the .exe generated by laun4j into a .jar,
    by exemple if i have converted a .jar into a .exe with launch4j and then i want to convert back this same .exe into .jar in order to find back my original .jar ?

  17. Jagan says:

    Hi Viral,
    ur posts are really good … thanks a lot :-)

    just wanted to add about JRE stuff .. jsmooth allows to point to a local JRE folder which can be shipped along with our product .jsmooth is another OSS wrapper for jar files files.
    (No installation required from user end).BUt that would add about 60mb to our distribution . Not really a problem if we are planning to distribute over a physical medium – Mem. Stick/CD/DVD

    Best setup packing options for a jar from my experience is
    IzPack + jsmooth

  56. maxxas says:

    I wrote an application which takes an .xls file with account information (account nr., swift code) and generates another .xls file, where IBAN and BIC code are there.

    The application works via an internet site (through AJAX controller), where it retrieves the IBAN and BIC with the help of account nr. and swift code (it takes some time until you’ve got the information). The output .xls is saved in the project directory ( writableWorkbook.write() ).

    The application works from JDeveloper but does not work from .jar or .exe file (I wrapped the .jar-file with launch4j). Do you have an idea what the problem could be? Thx in advance!..
