Frequently Asked Questions

Which video formats are supported?

Our Audio Extractor supports all popular video formats including MP4, WebM, MOV, AVI, and MKV. Compatibility is determined by your web browser's native decoding capabilities.

Is there a limit on file size?

There is no hard server-side limit because files are processed entirely on your local machine. However, extremely large files (e.g., above 500MB) may consume significant browser memory depending on your computer's hardware.

What audio format is generated?

The tool outputs the extracted track in WAV format. This ensures the output retains the highest possible audio fidelity without lossy compression.

Can I use this tool offline?

Yes. Once the webpage has loaded, all calculations and decoding processes run locally in your web browser. You can disconnect from the internet and the tool will continue to extract audio.
