A .3gp file is a lightweight container defined by the 3GPP standards body for video recorded and shared on mobile phones. It packs low-bitrate video and compressed speech with minimal overhead, which made .3gp the format of MMS messages and early camera phones.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.The Third Generation Partnership Project defined 3GP starting in 2001 so video could travel over the slow, expensive mobile networks of the era. The design derives from the MP4 base media file format, and a sibling called 3G2 served CDMA networks under the separate 3GPP2 group.
Android still opens most .3gp files, and desktop players such as VLC handle them, but iOS and web browsers generally do not. Because the codecs inside are dated, converting to MP4 with AAC audio is the standard path to modern playback.
A small set of 3GPP-defined asset atoms for title, author, and location exists, though most recording phones never wrote them.
