¿Qué es MP4 to MP3?
Extract the audio track from any MP4, MOV, AVI, or WebM video file and save it as a high-quality MP3 — entirely in your browser. No upload, no waiting, no watermark. Choose from 128, 192, or 320 kbps bitrates to balance file size and audio fidelity. Ideal for ripping audio from recorded lectures, interviews, podcasts saved as video, music videos, and more. Processing uses the Web Audio API for decoding and the lamejs encoder for MP3 output, so your video file never leaves your device.
¿Por qué usar MP4 to MP3?
- 100% private — your video file is never uploaded to any server. All decoding and encoding happens locally in your browser.

- Choose the MP3 bitrate that fits your use case: 128 kbps for podcasts and voice, 192 kbps for general music, 320 kbps for archival quality.
- Works with virtually every video format your browser can decode: MP4, MOV, AVI, WebM, and more.
- Instant results for short clips — longer videos show a real-time encoding progress bar so you always know where you are.

Consejos y buenas prácticas
- 💡128 kbps is sufficient for spoken-word content like podcasts and lectures. Use 320 kbps when audio fidelity matters, such as for music.
- 💡The output quality is capped by the source. If the video's audio was recorded at low quality, a higher bitrate setting will not improve it.
- 💡For very long videos (over 1 hour), the encoding step can take a minute or two — the progress bar keeps you informed.
Cómo se compara
Unlike online converters such as CloudConvert or Online-Convert, TinyTool's MP4 to MP3 tool never uploads your video to a server. This means there are no file size caps, no queues, and complete privacy. The trade-off is that encoding speed depends on your device — a modern laptop will encode a 60-minute video in under 2 minutes.
