Frequently Asked Questions

Absolutely safe. This tool uses advanced browser-based local processing technology. The entire extraction process is completed on your own computer, and your video files are never uploaded to our servers. This fully protects your privacy while also saving upload/download time and bandwidth.

What is the maximum video file size supported?

There is virtually no limit on the size of video files you can process. In practice, our tool can extract audio from videos up to an entire day long, making it suitable for full-length movies, long lectures, or multi-hour recordings—far beyond most online tools that only support small files (tens of MB).

Which audio formats can I convert my video to?

You can extract and convert video audio to MP3, WAV, FLAC (lossless), M4A, WebM, OGG, and more. In addition, we also support direct export to the iPhone-specific M4R ringtone format.

Will there be any quality loss in the extracted audio?

In the default “Auto” mode, the system intelligently selects the optimal output method and, whenever possible, directly extracts the original audio track without re-encoding. This preserves the original audio quality to the greatest extent and delivers lossless fidelity.

If a video contains multiple audio tracks (for example, bilingual tracks), can they all be extracted?

Yes. The tool features powerful multi-track detection and can easily identify and separate all independent audio tracks in a video, such as narration, background music, or multiple language tracks. You can extract all of them at once and choose which ones to download.
