How do I convert an MP4 video to 3GP in this converter?

Upload your MP4 file. Then select 3GP as the target format. Choose a mobile-appropriate resolution (176×144 for QCIF or 320×240 for QVGA) and set your preferred video/audio bitrate. Click Convert, wait for the re-encoding from H.264/AAC to H.263/AMR, and download the resulting .3gp file.

Why would I need to convert MP4 to 3GP instead of just playing MP4?

Many legacy feature phones, older car head units, and embedded devices only support 3GP because it uses a less demanding codec (H.263/AMR) compatible with low-power ARM processors. MP4 files are often H.264/AAC, which these devices can't decode. Converting to 3GP dramatically reduces resolution and bitrate, making the file much smaller and playable on this older hardware.

Will converting MP4 to 3GP preserve video or audio quality?

No. MP4 to 3GP is a lossy process. The video is resized and re-encoded to H.263/MPEG-4 Part 2, which uses a simpler compression algorithm, and the audio is converted to AMR-NB or AAC-LC at a significantly lower sample rate (typically mono, 12.2–32 kbps). Resolution drops to QCIF (176×144) or QVGA (320×240), and metadata, chapters, or subtitles are generally discarded. This is accepted as a trade-off for compatibility with 3G-era devices.
