Frequently Asked Questions

What video formats are supported?

We support all popular video formats: MP4, AVI, MKV, MOV, WebM, WMV, FLV, 3GP, TS, and M4V. If FFmpeg can read it, this tool can extract audio from it.

What is "quick extract" mode?

Quick extract copies the audio stream directly from the video without re-encoding. This is the fastest method and preserves original audio quality. For example, extracting AAC audio from an MP4 file gives you an M4A file with identical quality.

What is the maximum file size?

The recommended limit is 500 MB. Since all processing happens in your browser using WebAssembly, very large files may cause performance issues depending on your device. For best results, use files under 500 MB.

Can I extract audio from a YouTube video?

This tool works with video files on your device. You need to first download the video file, then use this tool to extract the audio.

Why is my video preview not showing?

Some formats like MKV, AVI, WMV, and FLV are not natively supported by browsers for playback. The preview will show a placeholder, but audio extraction will still work correctly.

Can I extract just a portion of the audio?

Yes! Enable the "Extract portion only" option and set start and end times. This is perfect for extracting a specific song, dialogue, or sound effect from a longer video.
