3GP is a multimedia container format developed by the 3rd Generation Partnership Project (3GPP) for 3G mobile phones. It was designed for extremely low bandwidth and processing power — perfect for the feature phones of the 2000s. 3GP files are tiny but very low quality. You might encounter them from old phone backups, MMS messages, or legacy mobile recordings.
3GP files tend to be very small compared to optimized MP4. Converting from 3GP to MP4 H.264 typically reduces file size by 40-80% while maintaining excellent visual quality. The resulting MP4 also plays on every device and platform without compatibility issues.
3GP was developed by 3GPP in 2003. It uses the 3GP (based on MP4) container and typically contains H.263/MPEG-4/H.264 encoded video. Browser support is very limited, and mobile support is legacy phones, android. For streaming, 3GP offers 3g mobile streaming capabilities.
Keep 3GP if you're doing professional editing and need the original codec quality. Convert to MP4 when: you need to share the video online, upload to social media, send via email, or reduce storage usage. For 99% of sharing and consumption purposes, MP4 is the better format.

When you upload a 3GP file, SquishVideo first analyzes the video stream to understand its codec, resolution, framerate, and bitrate profile. We then transcode the video to H.264 MP4 using optimized encoding parameters. The entire process preserves audio quality (re-encoded to AAC) and maintains the original resolution unless a lower resolution would provide a better quality-to-size ratio.
3GP files typically come from: old Nokia/Samsung phones, MMS messages, early Android recordings, and feature phone backups.
