What This Tool Does
This tool converts a WAR file into a ZIP file. A WAR is the ZIP-based deployment bundle for Java web applications, and this converter reads it entry by entry and writes a plain ZIP you can browse and reuse.
Classes, configuration files and libraries are preserved exactly. The result is not a deployable WAR any longer, it is a standard archive of the same content.
How It Works
Every entry of the WAR is copied into a freshly built ZIP. The ZIP is reopened and verified before the download link is offered, and the summary lists the number of entries carried over.
Step by Step
- 1
Upload the WAR file.
- 2
Click Convert to ZIP.
- 3
Wait for the entries to be copied.
- 4
Download your ZIP.
Compatibility
- WEB-INF structure and libraries are carried over intact.
- The output is a standard ZIP for any reader.
- Byte-for-byte entry contents throughout.
Troubleshooting
- Files that are not ZIP-structured are rejected clearly.
- A converted ZIP is content, not a deployable web application.
- Nested libraries inside WEB-INF/lib remain nested; the tool does not flatten them.
Frequently Asked Questions
What is a WAR?
A ZIP-based archive Java app servers use to deploy web applications.
Is data preserved exactly?
Yes, each entry is copied byte for byte into the new ZIP.
Can I deploy the ZIP?
No. It is a standard ZIP for access and reuse, not a deployment unit.
Will libs be flattened?
No, the folder layout, including WEB-INF/lib, is preserved.
Is verification done?
Yes, the output is opened again to confirm the entries before download.
