Can this repair old 3GP files from feature phones?

Yes. If the file still contains recoverable media data, rebuilding container metadata can often restore playback.

Do I need to convert 3GP to MP4 before repair?

No. You can repair 3GP directly first. Converting a corrupted file before repair can make recovery harder.

Can this fix 3GP files with no audio or no video?

Often yes when the issue is metadata corruption. If one stream is physically missing from the source file, repair may be partial.

Are 3GP files uploaded to a server?

No. Repair runs locally in your browser and keeps files on your device.
