Extract the audio track from any video file as MP3, WAV, AAC, FLAC, or OGG.
Video uploads are transferred via encrypted connections to ConvertCraft servers and processed in isolated containers. The audio extraction is purely computational — no audio content is stored, indexed, or analysed beyond the extraction process. All uploaded videos and extracted audio files are permanently deleted from our servers immediately after your download completes.
This tool demuxes the audio stream from a video container using FFmpeg's -vn (no video) flag. When the source audio codec is compatible with the target format (e.g. AAC to AAC, or MP3 to MP3), it uses stream copy mode (-c:a copy) for instant, bit-perfect extraction with zero quality loss. For incompatible pairs, it re-encodes using the target codec — libmp3lame for MP3, aac for AAC, pcm_s16le for WAV, flac for FLAC, or libvorbis for OGG. Output bitrate defaults to 192kbps for lossy formats and full quality for lossless formats.
Perfect for extracting the soundtrack from a movie clip for use as a standalone audio file, pulling voiceover audio from screen recordings, or converting video podcast recordings into downloadable audio episodes. Also useful for isolating music tracks from video content, extracting dialogue for transcription services, or creating ringtones from favourite video moments. Ideal when you only need the audio portion of a video file without the visual data.
