Lossy and lossless
MP3, M4A (AAC) and OGG (Vorbis) are compact lossy formats for everyday listening. WAV and FLAC are lossless — WAV is uncompressed and universally compatible, FLAC is compressed but keeps every bit of quality. Pick whichever suits the job.
Audio out of video, too
Drop in a video and the converter keeps only the audio track, so you can turn a clip into an MP3 or FLAC. Everything runs on your device with a WebAssembly build of ffmpeg; the first conversion loads it (~30 MB) once.
