Need deeper capabilities?

JD-GUI — Use a Java decompiler when you need reconstructed source-level methods and fields rather than an archive listing.

IMPLEMENTATION

Viewers responsible for this format

JAR is a ZIP-derived package for Java classes, resources and metadata. Anyfile reads the central directory and exposes a bounded file listing without starting Java or executing package code.

Archive metadata viewer

Archive metadata viewer: explore supported file formats, viewing limits and open-source credits. Your files are never uploaded.

Common question

Can opening a JAR run its application?

No. The archive viewer only inspects container entries and never launches Java.
