JAR, also called Java ARchive, is a file format that's principally used to aggregate Java class files, metadata, and resources into a single archive. This provides compression, as well as easy management for Java files. Interestingly, JAR format is based on ZIP, so there is a very close relation between these file types.
JAR and ZIP are closely related, and pretty much the same file format. However, some systems and programs work with ZIP file format, rather than JAR. As such, converting JAR to ZIP can help with compatibility issues in these situations.
JAR files are essentially ZIP files, so conversion can be pretty straightforward. In many cases, simply renaming the file extension from JAR to ZIP can do the trick. In case it is not possible to manually change file extensions, you can use online tools like uFileTool to handle the conversion. Finally, locally installed programs or apps like 7-Zip and WinZip can be used to convert JAR archives to ZIP archives.
While JAR and ZIP are very similar formats, the conversion can present a limitation because of the specialized nature of the JAR archives. Specifically, the metadata or specific functionalities within the JAR archive may not be handled as well with the ZIP format. In fact, there are chances that the Java manifest file might be ignored.
