Why Convert 3GP to MP4?
3GP was designed for early mobile phones with limited storage and bandwidth, producing small, low-resolution video files — but modern devices, video players, and platforms increasingly have poor or no support for the format.
MP4 is the format virtually every device, app, and platform expects, making conversion necessary the moment you want to play, edit, or share an old 3GP recording on current hardware.
Converting also makes the video compatible with modern editing and sharing tools, most of which were never built with 3GP support in mind.

Frequently Asked Questions
Will video quality improve after converting?
No — the conversion preserves the original video quality; it doesn't add detail that wasn't in the low-resolution 3GP source. It does make the file playable on modern devices, which is the main benefit.
Will the file size change much?
Since 3GP videos are typically already small and low-resolution, the converted MP4 stays roughly similar in size.
Does this work with old phone recordings and downloaded 3GP videos alike?
Yes — any standard 3GP file converts, regardless of source.
Do I need any special software installed?
No — the conversion happens entirely on our servers.
Is there a file size limit?
50MB free, 100MB for registered accounts.
