JAR (Java ARchive) is a package file format used to aggregate many Java class files, associated metadata, and resources (text, images, property files) into one file for distribution. JAR files use the ZIP file format as their basis, with a mandatory META-INF/MANIFEST.MF file that describes the archive contents, the main class for executable JARs, the class path, and other metadata. JAR was introduced with Java 1.1 in 1997.

JAR files are the standard distribution format for Java libraries, applications, and web applications (WAR files for web apps, EAR for enterprise apps are all JAR variants). Executable JAR files can be run directly with java -jar application.jar. JAR files can be digitally signed using jarsigner to verify their authenticity and integrity. The Java classpath system allows JARs to depend on other JARs, forming the basis of the Java library ecosystem (Maven, Gradle, etc.).

JAR files can be opened with any ZIP-compatible tool since JAR is built on the ZIP format. On Windows, 7-Zip, WinRAR, and WinZip can open JAR files. On macOS and Linux, the jar command (part of the JDK), unzip, and any archive manager can extract JARs. The JDK's jar tool provides the canonical way to create and inspect JAR files.

Since JAR is ZIP-based, converting JAR to ZIP is lossless and produces an identical archive with a different extension. Converting JAR to other archive formats like 7Z or TAR.GZ extracts the Java class files and resources for inspection or repackaging. LetsConvert makes JAR conversion straightforward for developers who need to inspect or repackage Java archives.
