Convert to MP3
MP3 is the most compatible lossy audio format, decodable by every player and device. This group re-encodes six audio formats to MP3 and extracts soundtracks from MP4, MOV, WebM and MKV videos โ 16 conversion directions in total.
The quality parameter (1-100) maps to a 64-320kbps bitrate; the default 80 corresponds to roughly 192kbps. Cover art and tag metadata are stripped on output to protect privacy and reduce size. Sample rate, channel and segment trimming are supported. Files are uploaded over HTTPS and deleted immediately after processing.
