Extracting audio to MP3 is perfect for turning talks, tutorials, interviews, and music videos into portable audio you can play anywhere — on your phone, in the car, or in a podcast app. Because everything runs locally in your browser using WebAssembly, your files stay private and you avoid upload waits and file-size caps that server-based converters impose. Choose a higher bitrate for music and a lower one for speech to keep files small.
Frequently Asked Questions
How does this video to MP3 converter work?
Drop your video into the browser, optionally select a clip range, choose your preferred audio quality, then click convert. The MP3 is created entirely on your device using FFmpeg WebAssembly — nothing is uploaded to any server.
Is this MP3 converter free to use?
Yes, completely free with no watermarks, no sign-up, and no hidden limits. You can convert as many videos as you want.
What video formats can I convert to MP3?
You can convert any video format your browser supports, including MP4, WebM, MOV, MKV, and AVI. The tool extracts the audio track and re-encodes it as a standard MP3 file.
Is my video uploaded to a server?
No. Your video never leaves your device. All processing happens locally in your browser using WebAssembly, so your files stay completely private.
What audio quality should I choose?
320 kbps gives the highest quality and is great for music. 192 kbps is the standard sweet spot for most uses, balancing quality and file size. 128 kbps produces the smallest files and works well for podcasts, voice, and speech.
Can I extract just part of the audio?
Yes. Use the clip range slider to select a start and end point, and only that portion will be extracted. Leave the full range selected to convert the entire audio track.
Why does it say my video has no audio track?
Some video files are recorded or exported without an audio stream (for example, screen recordings with sound disabled). There's nothing to extract in that case, so no MP3 can be produced.
Is there a maximum video length or file size?
The tool accepts files up to 500 MB. There is no hard limit on duration, but very long videos take longer to process since everything runs on your own device.
