FAQ

Frequently Asked Questions

What video formats are supported?

This tool supports all major video formats including MP4, MKV, MOV, AVI, WebM, FLV, WMV, and many more. As long as the file contains an audio track, it can be extracted to your preferred format like MP3 or WAV.

Is my video file uploaded to a server?

No. This tool uses WebAssembly (WASM) technology to process your files entirely within your browser. Your video data never leaves your device, ensuring complete privacy and security.

What is the best output format to choose?

MP3 is the most universally compatible format, perfect for mobile devices and music players. WAV and FLAC are ideal for professional, lossless audio. AAC offers a great balance of quality and file size for streaming.

Is there a file size limit?

There is no server-side limit since all processing is done locally. The practical limit depends on your device's available RAM. For best results, we recommend processing files under 2 GB.

How long does the conversion take?

Conversion is extremely fast because the audio is being demuxed (extracted) rather than re-encoded from scratch. A 1-hour video file can typically be processed in under 30 seconds on a modern device.

How to extract audio from video using this tool?

Simply drag and drop your video file into the dropzone, choose your output format (like MP3, WAV, or AAC), select the quality, and click 'Extract Audio'. Your file will be ready for download in seconds.

Can I convert multiple videos at once?

Yes! Our batch processing engine allows you to add multiple video files and extract their audio tracks sequentially without having to refresh the page or restart the process.

Is it safe to use this audio extractor?

Absolutely. Unlike traditional online converters that re-encode your videos on their servers, our extraction happens 100% locally. This means your private videos are never seen by us or anyone else.
