FAQ
Is converting MP4 to AVI 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 MP4 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.
