To convert JAR to ZIP, select or drop your .jar file above, check that ZIP is chosen as the output, and click Convert. Files up to 200 MB are converted right in your browser, so they never leave your device.
What is a JAR file?
JAR – Java archive. JAR is a Java application packaged as a ZIP archive, with an added manifest in its META-INF folder.

ZIP – ZIP archive. ZIP is the most widely supported archive format: every operating system opens it without extra software. It compresses each file separately, usually with Deflate, so single files can be pulled out quickly.

Good to know
- A JAR already is a ZIP archive with a Java manifest, so renaming .jar to .zip also works. Converting gives a plain ZIP with the same files, META-INF folder included.
- Symbolic links, hard links and special files (such as devices) are left out of the result for safety; the page tells you when it does this.
Frequently asked questions
Is converting JAR to ZIP free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my JAR files uploaded anywhere?
Files up to 200 MB never leave your device: ConvertKitty runs 7-Zip inside your browser. Only larger files, or formats your browser cannot handle, are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.
How large can the JAR file be?
Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.
Will the folders inside my JAR be kept?
Yes. The ZIP has the same folders and file names as the JAR. Only links and special files are left out, and the page tells you if it did that.
Can I convert several JAR files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
