Recommended FFmpeg settings
3GP (3GPP file format) is a video container designed in 2001 for 3G mobile phones. It was the standard video format on early camera phones (Nokia, Sony Ericsson, Motorola Razr era). 3GP files are tiny by design — optimized for 64kbps data connections and 176×144 screens. The format is essentially extinct on modern phones but lives on in archives of early-2000s mobile videos. This 3GP compressor decodes 3GP input and re-encodes to H.264 MP4 at CRF 28, typically reducing file size 50-80% while preserving quality acceptable for web and social media. The output is a universally-compatible MP4 file with AAC stereo audio and the +faststart flag for instant streaming playback across browsers, phones, tablets, and smart TVs. Compressing 3GP before sharing means your video plays everywhere without compatibility headaches.
- 1Universal playback. Modernizing 3GP also typically upscales to a more reasonable resolution and frame rate, though source quality is the limiting factor.
- 23GP files commonly contain codecs like H.263 (most common), MPEG-4 Part 2, or H.264 (newer 3GP). Audio is AMR-NB (narrowband) or AMR-WB (wideband) — extremely low bitrate voice codecs.
- 3Typical sources include Old mobile phone video recordings (Nokia 6600, Sony Ericsson K750, etc.), MMS video messages from 2005-2012 era phones, Early 3G video calling archives, and similar.
- 4Local processing means no upload bandwidth and no server storing your files.
- 5Free, no account, no watermark — compress unlimited videos.
- 6CRF 28 encoding is tuned specifically for typical 3GP content profiles, preserving source quality.

Frequently asked questions
The tool decodes your 3GP file and re-encodes the video stream to H.264 with Constant Rate Factor (CRF) compression. Audio is converted to AAC. The result is wrapped in an MP4 container for universal compatibility. Typical size reduction is 50-80% for 3GP sources, depending on the original codec and bitrate.
