1JAR is an application developed by Ibrabel that will help you compile all JAR files and its other necessary extensions into one executable file. With just a few clicks, you will be able to have your very own executable and independent JAR file package that you can share with others.

Downloading and installing the program is very quick and easy. The moment you run 1JAR, you will be welcomed by its straightforward interface where all you have to do is type in a name for your JAR file, upload the necessary JAR files and libraries, and upload your desired splash screen which can come in various supported formats. The splash screen will appear as your cover when the JAVA pack you created is launched. Some of the file formats this supports are JPEG, TIFF, and GIF. Once you are all set, you can now start processing the file. Its progress will be displayed so you have an idea about its status. Aside from that, if you happen to change your mind, you can also pause or cancel it.
