Convert JAR to RAR

Both JAR and RAR formats are used for compressed archives, so it should be possible to repack the contents freely between formats you like. Alternatively, JAR files can be further compressed into RAR files, but that isn't jar to rar conversion, and the file size will not be significantly reduced.

Repacking contents between JAR and RAR formats can offer advantages such as increased compatibility and improved compression. Converting a JAR file to a RAR file allows for easier sharing and distribution, especially if the recipient does not have a program to extract JAR files. Compressing a JAR file into a RAR file may result in a smaller file size, saving storage space and facilitating faster downloads.
