Upload your video, extract the audio track as MP3, download it. Free, no sign-up, works entirely in your browser.
Whether you want to save a song from a music video, pull a podcast-style interview out of a screen recording, or just need the audio for editing elsewhere, the tool decodes your video's audio track and encodes it straight to MP3 in your browser — the video itself is never touched or re-encoded.
Is it free?
Yes, no account needed.
Does my video get uploaded anywhere?
No, audio extraction runs entirely in your browser.
Which video formats are supported?
mp4, mov, webm, mkv, and avi, up to 300MB.
What does the output quality depend on?
The original video's audio quality; the tool encodes the audio to MP3 at high quality without adding extra loss.
Can I extract audio from just part of the video?
Not currently — the whole video's audio track is extracted. You can trim the part you want first with Stelluna's Video Trimmer, then upload the result here.
What MP3 bitrate does it use?
The extractor encodes at a fixed, high bitrate suited for both music and speech, so there's no extra setting to fuss with — just click Convert to MP3 and get a good-quality file.
Is my video or the MP3 stored anywhere afterward?
No. Everything happens in your browser's memory, so closing the tab or refreshing the page clears both your original video and the extracted MP3 — nothing is uploaded or kept on a server.
Which devices and browsers does it work on?
Any modern browser with WebCodecs support — recent versions of Chrome, Edge, Firefox, and Safari, on desktop or mobile. If your browser doesn't support the required APIs, you'll see an error when you try to extract the audio.
