Video to MP3 Converter
Runs in your browserExtract the audio track from any video and save it as MP3 or WAV. Trim to a clip, pick the bitrate, and download — the file never leaves your device.
The fastest way to rip audio out of video
Most “video to MP3” sites are a detour: you upload your file to a server you don't know, wait for a queue, download a watermarked result, and hope your video never shows up on a shady thumbnail aggregator. This tool works differently. It runs entirely inside your browser tab, so the video never leaves your device — and because there's no upload step, the conversion usually finishes before a server-based tool would have even accepted the file.
Under the hood, the video is demuxed so we can isolate the audio track, then that track is re-encoded directly to MP3 (via the browser's built-in AudioEncoder) or WAV (lossless PCM). No FFmpeg round-trip, no intermediate uploads, no watermark.

Why extract audio from video?
Podcasts & interviews
Strip the audio from a recorded Zoom or webinar MP4 and publish it as a podcast episode. 128 kbps MP3 is the sweet spot for spoken-word — clear voices, small files.
Music videos & concerts
Rip the soundtrack out of a concert clip to listen offline. Use 256 or 320 kbps MP3 to keep musical detail intact.
Transcription & subtitles
Audio-only files upload to transcription services faster than video and cost less. Or run the audio through our AI subtitler to get timed captions back.
Editing in a DAW
Export to WAV when you're pulling the audio into Logic, Ableton, Audacity, or Reaper. Lossless PCM keeps every sample intact for mastering or restoration work.
Ringtones & sound clips
Trim a 10-second clip from a movie or show with the Start/End sliders, then drop the MP3 into your phone as a ringtone or notification sound.
Archiving lectures
A 1-hour lecture MP4 is often 1–2 GB. The same audio as 128 kbps MP3 is under 60 MB — much easier to store, sync across devices, and re-listen to while commuting.
MP3 vs WAV: which should you pick?
| Attribute | MP3 | WAV |
|---|---|---|
| File size | ~1 MB / min at 128 kbps | ~10 MB / min at 44.1 kHz 16-bit |
| Quality | Lossy; near-perceptually transparent at 192 kbps+ | Lossless PCM |
| Use case | Sharing, streaming, podcasts, phones | Editing, mastering, archiving |
| Compatibility | Every device made in the last 25 years | Everything pro audio; most consumer players |
How It Works
Upload a video
Drag and drop your MP4, MOV, WebM, MKV, or AVI — or click to pick a file. Audio files work too.
Pick MP3 or WAV
Choose MP3 (small files, universal) or WAV (lossless). Set bitrate and trim the start / end if you only want a clip.
Download the audio
Your MP3 or WAV is ready to save, share, or transcribe. No watermark, no sign-up, no uploads.
Frequently Asked Questions
How do I convert a video to MP3?
Drop your video onto the uploader, keep MP3 selected, and click Extract MP3. We demux the audio track out of the container and re-encode it to MP3 right in your browser. Download the file when it's done.
Does my video get uploaded to a server?
No. The entire conversion runs on-device using WebCodecs and MediaBunny. Your video, your audio, and everything in between stays in your browser tab — nothing is sent to our servers.
What file formats can I convert from?
Any video your browser can read: MP4, MOV, WebM, MKV, AVI, M4V, FLV, 3GP, and more. You can also drop in audio files (M4A, AAC, FLAC, OGG) to convert between audio formats.
What's the difference between MP3 and WAV?
MP3 is compressed — small files, tiny quality tradeoff, plays everywhere. WAV is uncompressed PCM — much bigger files, zero encoding loss, the format professional editors and DAWs expect. Pick MP3 for sharing, WAV for editing.
Which MP3 bitrate should I use?
128 kbps for spoken-word content (podcasts, lectures). 192 kbps is a safe default for most music. 320 kbps is near-CD quality — use it if you're archiving or the source audio is high quality to start with.
Can I extract just part of a video?
Yes. After uploading, drag the Start and End trim sliders to pick the clip you want. Only that range is encoded — so a 30-second extract from a 2-hour video takes seconds, not minutes.
Is there a file size limit?
No hard cap imposed by the tool — the limit is your device's memory. In practice a modern laptop handles multi-gigabyte videos without issue. Longer videos take longer to process.
Does it work on my phone?
Yes, on modern iOS and Android. iOS Safari added WebCodecs support in version 17, which is what powers the MP3 encoder here. Older devices may fall back to WAV only.
Will there be quality loss?
WAV is lossless — bit-perfect PCM out of the source. MP3 involves a single encoding pass; at 192 kbps or higher most listeners can't tell the difference from the original. Converting between two MP3 files introduces some loss; going video → MP3 once is fine.
Do I need an account or pay anything?
No account, no payment, no watermark. The tool is free because it runs in your browser — there's no server cost to pass on.
