MP4 to AAC Converter
Extract the audio from a MP4 video as a AAC file.
To convert MP4 to AAC, upload the video and the audio track is extracted and encoded as AAC. AAC is the successor to MP3 and sounds better at the same bitrate. It is what Apple Music, YouTube and most streaming uses. Everything runs in your browser through FFmpeg compiled to WebAssembly, so the video is never uploaded.

AAC is the successor to MP3 and sounds better at the same bitrate. It is what Apple Music, YouTube and most streaming uses. Extracting audio from video is a re-encode, not a copy, so the result is bounded by the quality already in the source — a 96 kbps track exported at 320 kbps gains nothing but file size.
