Any video in, just the audio out
This tool takes whatever container you hand it — an .mp4 from your phone, a .mov from a screen recorder, a .webm pulled off the web, an .mkv from a download — and strips the video stream entirely, leaving only the soundtrack. There's no format-specific wrangling on your end: the same drop zone handles all four. If you specifically have an MP4, the dedicated MP4 to MP3 converter does the same job, but this page is the one to reach for when the source could be anything.
MP3 for sharing, WAV for editing
The format toggle isn't cosmetic — the two outputs serve genuinely different needs. MP3 is compressed (we encode VBR around 190 kbps), so it's small enough to email, drop in Slack, or upload to a podcast host without a second thought. WAV is uncompressed 16-bit PCM: it's much larger, but it's lossless and it's what audio editors and DAWs like Audacity, Logic, and Premiere expect when you want to clean up noise, normalize levels, or layer it into a mix. Pick MP3 if the file is the deliverable; pick WAV if it's raw material headed into an editor.
Three jobs this solves in one click
The common cases are clear. You recorded an interview or panel and want a podcast episode from the audio alone. You're feeding a clip into a transcription service and an audio file uploads faster and costs less than the full video. Or you just want to listen to a recorded talk on your phone with the screen off — something iOS won't do cleanly from a video file. All three start with extracting the audio, and all three are done the moment the download lands.
You might not need to extract at all
If the reason you're here is transcription, there's a shortcut. Clipy records your screen and auto-transcribes every clip the moment you stop — so the text is waiting for you without ever pulling the audio out by hand. And if you're extracting just to share the sound, a hosted Clipy link plays inline anywhere with no download step for the viewer. Extraction is the right move for editing and podcast workflows; for transcripts and sharing, recording with Clipy skips it entirely.
