3GP was the video format of mobile phones in the 2000s. The files are tiny, often 176×144 or 320×240, with AMR or AAC sound.
Many current phones and computers no longer play 3GP, especially with AMR sound. Converting gives an MP4 with H.264 video and AAC sound. Files your browser can’t read are converted with ffmpeg in the page. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
