Convert 3GP to iPhone Video — Free Online Converter

3GP was the standard recording format on pre-smartphone mobile phones, storing video encoded with H.263 or MPEG-4 Part 2 and audio in AMR at resolutions from 176x144 to 720x480. iPhones require video in H.264 or H.265 format within MP4 or MOV containers, with AAC audio, to leverage the A-series chip's hardware decoder. Converting 3GP to an iPhone-optimized profile ensures native playback in the Photos app, Messages, and FaceTime, with full support for sharing, editing, and AirDrop.

iPhones do not reliably play 3GP files — the Camera Roll ignores unknown containers, and most iOS apps cannot handle H.263 video or AMR audio. Converting to iPhone video (H.264 Baseline or Main profile, AAC-LC, MP4 container) enables hardware-accelerated decoding that saves battery and ensures smooth playback. The conversion also produces files that are instantly shareable via iMessage, AirDrop, and social media apps without any additional transcoding by the receiving app.
