Drop a video and get its sound as a file you can edit, transcribe or use under another clip. MP4 and MOV audio is copied as it is, without converting it, so it takes seconds and sounds exactly like the original.

Read in this page from your own disk - the file never leaves your computer.
Most online converters decode the sound and encode it again as MP3. Every pass loses a little, and the bigger the file the longer the queue.
An MP4 or MOV already holds its audio as a separate stream, usually AAC. This tool lifts that stream out into an .m4a file unchanged: same quality, same length, ready in seconds even for a long recording.
Other formats are decoded by your browser and saved as WAV, which every editor opens. WAV is uncompressed, so those files are bigger.
