Video to MP3 Online Free

Frequently asked questions

How do I extract MP3 from a video online?

Upload your video (MP4, WebM, MOV, AVI, or MKV). Click "Extract MP3". FFmpeg.wasm runs in your browser and produces a high-quality MP3. Download the file. Your video never leaves your device.

Are my files sent to a server?

No. Extraction runs entirely in your browser using FFmpeg.wasm. Your video never leaves your device.

What if the video has no audio?

If the video has no audio track, the tool will show an error. Only videos with an audio stream can be converted to MP3.

What quality is the MP3?

The tool uses -q:a 2 (high-quality VBR, roughly 190 kbps average). Good for music and speech.

What video formats are supported?

MP4, WebM, MOV, AVI, and MKV. The tool reads the audio and encodes it to MP3.

Why does FFmpeg take a few seconds to load?

FFmpeg.wasm is a large WebAssembly module. It is downloaded once and cached. The first time you use the tool you will see a short loading state.

Does it work on mobile?

Yes, in browsers that support WebAssembly. Chrome and Safari on mobile work. Longer videos may take more time on slower devices.

Can I extract from a streaming video?

You need to upload a video file from your device. The tool does not accept URLs or streaming sources.

Is there a length limit?

There is no fixed limit. Very long videos may take longer and use more memory. Limits depend on your device.

Does it work in all browsers?

FFmpeg.wasm requires a modern browser with WebAssembly. Chrome, Firefox, Safari, and Edge (recent versions) work.
