    JAR: JAR is a ZIP-based archive holding Java classes and resources. Open it to inspect or extract its contents.

    ZIP: ZIP is the universal archive format. It bundles many files and folders into one compressed file, and every computer and phone can open it without extra software.

    Frequently asked questions

    Will my files change when converting JAR to ZIP?
    No. Archive formats are lossless, so every file is restored bit for bit and packed again.
    My JAR is password-protected — can I convert it?
    Yes. Enter the password when asked. You can also set a new password on the output (ZIP and 7Z).
    Is there a size limit?
    No fixed limit. It depends on your device's memory: several GB on computers, a few hundred MB on phones.
    Are my files uploaded?
    No. Everything runs in your browser with 7-Zip compiled to WebAssembly.
