Frequently Asked Questions

Can I choose the audio quality?

Yes. You can select bitrate from 128kbps to 320kbps. 320kbps offers the highest quality.

What is the difference between WAV and MP3?

WAV is uncompressed so files are larger but with no quality loss. MP3 is compressed, providing good quality at much smaller file sizes.

What is the difference between MP3 and M4A?

MP3 is the most widely supported format, but M4A offers better sound quality at the same bitrate. M4A is natively supported on Apple devices.

Can I extract audio from a YouTube video?

VideoTools works with local files only. You need to first download the video from YouTube, then use that file here.

Why is M4A extraction so much faster?

M4A uses stream copy (no re-encoding). It simply moves the audio data into a new container, which is why it finishes in seconds.

Is my video uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly technology. Your video data never leaves your device, ensuring complete privacy.

Is this tool free?

Yes, it's completely free. No account registration required, and there are no usage limits.
