Question 1

Will extracting audio upload my video?

Accepted Answer

No. Extraction happens locally in your browser. The video never leaves your device and is not uploaded to any server.

Question 2

Which video formats are supported?

Accepted Answer

Most common video formats are supported (MP4, MOV, MKV, AVI, WebM, FLV, etc.), allowing you to extract audio tracks and save them as audio files.

Question 3

What is the quality of the extracted audio?

Accepted Answer

Choosing WAV / FLAC preserves the original track losslessly. For MP3 / M4A / Opus, it's recommended to set the bitrate no lower than the source track to minimize quality loss.

Question 4

Why is there a loading wait on first use?

Accepted Answer

The first time, the processing engine (about 30MB) is downloaded. After that, it's cached by the browser, so subsequent use requires no re-download and even works offline.
