When you need to convert video to MP3
Six common workflows where extracting the audio track is the whole job.
Podcast prep from video
Recorded a Zoom or Riverside conversation as MP4? Extract the audio for your podcast host. Most hosts (Buzzsprout, Anchor, Castos) want MP3 only.
YouTube voiceover assets
Have an MP4 from your own YouTube upload? Pull the audio out for use elsewhere — reels, shorts, podcasts, transcript generation.
Audiobook recordings
Authors who record reading sessions on Zoom can extract the audio for distribution on Audible, Spotify, or Google Podcasts.
AI voice training data
Building a voice clone or accent model? Extract clean audio from video recordings of the target speaker.
Music from music videos
Extract audio from your own music videos for separate distribution. Useful for artists prepping multi-platform releases.
Language learning clips
Pull individual phrases from movies, dramas, or interviews for pronunciation practice. Works great with Indian-language films.
How to extract audio from video
Convert MP4, MKV, WebM, MOV, AVI, FLV, or any common video format to MP3 in under a minute.
- 1
Upload your video file
Click the upload area or drop in any MP4, MKV, WebM, MOV, AVI, or FLV video. Your file stays on your device — nothing is uploaded to any server.
- 2
Choose MP3 quality
Pick 128, 192, 256, or 320 kbps. 192 kbps is the recommended sweet spot — indistinguishable from the original audio track for most listeners.
- 3
Click Extract Audio
The extractor loads on first click (~2.5 MB of WebAssembly code). It demuxes your video, ignores the video track entirely, and re-encodes only the audio as MP3.
- 4
Download the MP3
The MP3 saves to your device immediately when extraction completes. No watermark, no signup, no daily limit. Subsequent extractions reuse the cached extractor.
Supported video formats
The converter reads any common video container. The internal audio track (AAC, MP3, Opus, Vorbis, AC3) is auto-detected.
Video never leaves your device
ytmp3, FLVTO, Convertio, and the other big online video-to-MP3 tools all upload your video file to their servers, run the extraction there, and serve a download link. That means your video sits on their infrastructure — often for an unspecified retention period.
This tool runs entirely client-side using WebAssembly — the same browser technology that powers in-browser video editors. Only the extractor code itself (~2.5 MB) loads from a CDN on first use. Your actual video makes zero network round-trips.
Verify it: open DevTools then Network tab, drop in a video, hit Extract. The only request you will see is the extractor code download on first use — and nothing during the actual extraction.

Frequently asked questions
Everything people ask about converting video to MP3.
Is this video-to-MP3 converter really free?+
Yes — fully free, no signup, no watermark, no time or file-size limit, and no daily quota. The whole tool runs in your browser so it costs us nothing to operate.
Does my video get uploaded?+
No. The extraction runs locally in your browser tab via WebAssembly. Only the extractor code itself (~2.5 MB) is fetched from a CDN. Your actual video never touches the network.
Which video formats are supported?+
Almost every common video container: MP4, MKV, WebM, MOV, AVI, FLV, M4V, 3GP, MPG, MPEG, TS, WMV, VOB. The audio track inside (AAC, MP3, Opus, Vorbis, AC3, FLAC) is auto-detected and decoded.
Is there a file-size limit?+
The only limit is your device memory. Desktop browsers handle videos up to ~1 GB reliably. Mobile browsers may struggle past 200-300 MB on low-end devices. The extraction itself is fast — most of the wait is reading the file into browser memory.
How fast is the extraction?+
A 10-minute MP4 (~80 MB) typically extracts in 3-8 seconds on a modern laptop, 10-20 seconds on a mid-range phone. The first extraction includes a one-time ~2.5 MB code download. Subsequent extractions in the same session start instantly.
Which bitrate should I pick?+
For most use cases, 192 kbps. It is indistinguishable from the original for most listeners and keeps the file roughly 1.5 MB per minute of audio. Use 320 kbps for music videos where audio fidelity matters. Use 128 kbps for talking-head content like interviews or vlogs where size matters more than quality.
Does it work for YouTube videos?+
This tool extracts audio from video files you already have on your device. To get audio from a YouTube video, first download the video legally (only your own uploads or videos that explicitly permit download), then drop the file in here. We do not download YouTube videos for you — that would require third-party services that often violate YouTube terms.
How is this different from ytmp3, FLVTO, or Convertio?+
Those tools upload your video to their servers, queue it, watermark output, and often inject ads or trackers. This tool runs entirely in your browser, has no signup, no watermark, no quota, and no ads. It also handles much larger files because there is no upload step.
Can I use this for podcast workflows?+
Yes — this is one of the most common use cases. Record a video conversation, drop it in here, get an MP3 ready for your podcast host. The MP3 quality is identical to what you would get from a desktop ffmpeg command.
Is this legal?+
Using this tool is legal. What you do with the output depends on the source video. Only extract audio from content you own, content licensed for reuse, or content where the platform explicitly permits download. We do not endorse using this for pirated content or anything that violates copyright.
