FAQ

Is converting JAR to ZIP free?

Yes. Unlimited conversions, no sign-up, no watermark.

Are my files uploaded to a server?

No. FieldConvert processes files inside your browser, so your JAR files never leave your device. That makes it private and fast, because there is no upload or download wait.

Is there a file size limit?

Only your device's memory. Files up to about 2 GB work in most desktop browsers.
