Video to MP3 — free, in your browser
Short answer: drop an MP4, MOV, WebM or MKV into the box above. The tool reads the video's audio track right on your device, lets you trim a start/end clip, encodes it to MP3 (128–320 kbps) or lossless WAV, and hands you the download. No signup, no upload, no waiting on a server queue.
People use it to pull a song out of a video clip, save a podcast episode's audio from a recording, grab a voiceover from a screen capture, or cut a 30-second ringtone from a longer video. Because the whole pipeline runs locally, even large files convert fast — the only limit is your device's memory.
How it works
1. Drop your video onto the box (or tap it on your phone) — MP4, MOV, WebM, MKV. 2. The tool reads the file's metadata for its duration and quietly decodes the audio track in the background. 3. Optionally set start/end times to extract just a clip. 4. Pick MP3 (choose a bitrate) or WAV (lossless) and click Extract audio — your file downloads, named after the video.
Most videos take the fast path: the audio track is decoded directly and rendered faster than realtime. A few unusual containers can't be decoded that way — for those the tool falls back to realtime capture, silently playing the video and recording its audio. It tells you honestly when this happens: a 3-minute clip takes 3 minutes, so keep the tab visible.
MP3 vs WAV: which should you pick?
MP3 is the everyday choice — small files (a 3-minute track is roughly 3–7 MB at 192 kbps) that play on every phone, car stereo and app. At 256–320 kbps it's effectively indistinguishable from the original; 128 kbps is fine for speech and saves space.
WAV is the pro choice — uncompressed 16-bit PCM, bit-identical to the audio decoded from your video. Use it when you're editing in Audacity or Premiere, feeding a transcription tool, or archiving at full quality. Files are bigger (about 10 MB per minute of stereo), but nothing is lost.
Frequently asked questions
Is this video to MP3 converter really free?
Yes — unlimited conversions, no signup, no watermark. Everything runs in your browser, so there are no server costs to pass on to you.
Are my videos uploaded anywhere?
No. Your video never leaves your device. The audio track is decoded, trimmed and encoded locally in your browser — you can verify this in your browser's Network tab. Nothing is stored or tracked.
Should I download MP3 or WAV?
Choose MP3 for listening and sharing — it is much smaller (a 3-minute song is about 3–7 MB) and plays everywhere. Choose WAV for editing — it is lossless 16-bit PCM, bit-identical to the video's decoded audio, which is what audio editors and transcription tools prefer.
Will the extracted audio sound exactly like the video?
WAV output is bit-identical to the audio decoded from your video — zero quality loss. MP3 re-encodes the audio; at 256 or 320 kbps the difference is inaudible to virtually all listeners, while 128 kbps saves space with a small quality trade-off.
What is realtime capture and when is it used?
Most videos (MP4, MOV, WebM) have their audio track decoded instantly in your browser. A few unusual containers cannot be decoded directly — for those, the tool plays the video silently and records its audio in realtime. A 3-minute clip takes 3 minutes to capture, so keep the tab visible until it finishes.
Can I extract just part of a video's audio?
Yes. After your video loads, its duration appears above the trim controls. Set a start and end time (in seconds) to extract only that clip — for example a 30-second segment for a ringtone. Leave them untouched to convert the whole video.
Is there a file size limit? Does it work on my phone?
There is no server-side limit because nothing is uploaded — the practical limit is your device's memory. Phones comfortably handle typical clips; very long videos (an hour or more) are best processed on a desktop. The tool works in any modern mobile or desktop browser.
Can I extract audio from YouTube or other streaming videos?
No — this tool works on video files saved on your device, not on streaming links. And a copyright note: only extract audio from videos you recorded yourself or have permission to use. Extracting audio does not change who owns it.
