A .arj extension file is a file that is compressed using the ARJ archiver. The program was developed by Robert K. Jung and hence the extension .arj stands for Archived by Robert Jung. ARJ was initially developed in 1990 for DOS and for the earlier versions of Windows. It was a very popular format for compression in the early days because it was very efficient at file compression. It was highly popular at the time of early networks. It is fast, reliable and helps to save on disk space.
A .jar extension file is a Java Archive format file that is used to store a large number of files into one single file. The basic advantages of .jar extension files are data compression, archiving, decompression, unpacking of the archived file and electronic signing which is one of the advanced features of this format. The Java Development Kit (JDK) contains the Java Archive Tool that is used to perform the basic tasks on .jar extension files. The JAR format is similar to a ZIP file format and it was specifically developed to help download Java applets and its components that include class files, images and sounds in one single HTTP transaction.
FreeFileConvert uses tuned encoding for ARJ to JAR conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload ARJ files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized JAR results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent JAR audio with dependable progress tracking.
The .arj file format supports data integrity protection, multiple volume archives, file version management, long file names acceptability, configurable options for commands and ANSI based escape sequence for display handling. This format is used to create high-efficiency archives of compressed files. The .arj file extension has advanced features which made it easy to split up a single archive into small chunks.
A .jar file contains the Java source code, a manifest file, XML based configuration data, JSON-based data files, images and sound clips as well as security certificates. These files use a standard compression algorithm and hence can be easily opened by extracting the contents of the file with a standard decompression tool like the tool used to extract .zip extension files.
Upload your archive file in the ARJ format from your device, Dropbox, or Google Drive.
Select JAR as the output format and click Convert. Adjust optional settings if needed.
