Inspect JAR Package Contents Online
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.
Choose a .jar fileYour file stays on this device
Anyfile reads only the local file you select. Parsing, decoding and rendering happen in this browser tab; the file is not uploaded to Anyfile servers.
What Anyfile can show
- Archive entry paths, sizes and compression
- Container-level metadata
- Safe directory navigation
Limits and conditions
- Class files are not decompiled
- Encrypted, corrupt or extreme archives can be rejected by safety limits
Need deeper capabilities?
JD-GUI — Use a Java decompiler when you need reconstructed source-level methods and fields rather than an archive listing.

Common question
Can opening a JAR run its application?
No. The archive viewer only inspects container entries and never launches Java.
