Audio extraction FAQ

Is MP3 the only output format?

No. MP3 is preselected as a convenient default, including on pages named “to MP3,” but you can choose AAC, M4A, WAV, OGG, Opus, or FLAC from the output menu.

Can I extract audio from only part of a video?

Yes. Open Options and set the Start and End times before extracting. Leave them blank when you want the complete audio track.

Which audio track is extracted?

The tool extracts the first audio track. If a video contains several languages, commentaries, or other audio streams, use a track-aware editor when you need a different one.

Are my video files uploaded?

No. The selected video is processed in this browser tab and is not uploaded to a server by this tool.

Why can large videos take longer to process?

Processing time depends on the video's duration, file size, output settings, and your device. The first extraction may also take longer while the browser prepares the required media tools.
