Frequently asked questions

Is this audio extractor free?

Yes. You can extract audio from videos for free without signup, software installation, or a watermark.

What output formats can I download?

Choose MP3, WAV, M4A, AAC, or Original audio. Original keeps the embedded audio stream when it can be placed in a safe audio file.

Does Convertr reduce audio quality?

Convertr stream-copies the original audio when the selected output can safely hold it. If you request another format, ffmpeg transcodes the audio to that target format.

Which audio stream is extracted from videos with multiple tracks?

The first audio stream is extracted. The tool shows when multiple audio streams are detected so you know the file has more than one track.

What is the maximum upload size?

The upload limit is 1 GB, matching the rest of Convertr. Full-resolution videos are supported when the file is within that limit.
