Frequently Asked Questions
3GP is a compact video format designed for mobile phones. Converting MOV to 3GP makes videos compatible with older feature phones, suitable for MMS, and dramatically reduces file size for mobile sharing.
3GP files are typically 60-90% smaller than equivalent MOV files. The exact size reduction depends on the source MOV's resolution, bitrate, and codec.
Yes, most Android devices natively support 3GP playback. It was the standard mobile video format for many years before MP4 became dominant.
3GP uses higher compression at lower resolutions, so quality is reduced compared to the original MOV. It's optimized for small screens and mobile viewing rather than high-fidelity playback.
Yes. MOV files recorded on iPhone are fully supported. The iPhone's H.264 or H.265 video will be transcoded to 3GP's H.264 encoding.
Yes. All uploads use HTTPS encryption. Files are processed on isolated servers and deleted immediately after your download completes.
Up to 50MB is supported. iPhone MOV files can be large — trim the clip or reduce the resolution before uploading if needed.
