Separate Audio from Any Video File

The SaveOnlineVideos Audio Extractor lets you separate the audio track from any video file and save it as MP3, WAV, or AAC. This is perfect for extracting music, dialogue, narration, or sound effects from video recordings. Whether you recorded a lecture, a concert, a podcast with video, or need the soundtrack from a clip, this tool extracts audio quickly and privately in your browser.

Powered by FFmpeg WebAssembly, the extractor processes everything locally on your device. Your video files are never uploaded to any server, ensuring complete privacy. The tool supports all major video formats and outputs in three popular audio formats to suit different needs. MP3 offers the best compatibility, WAV provides lossless quality, and AAC delivers excellent quality at smaller file sizes.

Frequently Asked Questions

What audio formats can I extract to?

You can extract audio in three formats: MP3 (most compatible, smaller files), WAV (uncompressed, highest quality), and AAC (modern format, great quality at small sizes). MP3 is recommended for most use cases due to its universal compatibility.

What video formats are supported?

The audio extractor accepts MP4, WebM, MOV, AVI, MKV, and other common video formats. Any video file that contains an audio track can have its audio extracted.

What if the video has no audio?

If the video file does not contain an audio track (such as a silent screen recording or a video-only stream), the tool will show an error message. Most video files from cameras, phones, and screen recorders include audio tracks.

Does extraction reduce audio quality?

When extracting to MP3 or AAC, the audio is re-encoded which may cause minor quality loss. For lossless extraction, choose WAV format. The MP3 output uses high quality settings (VBR quality level 2) which produces excellent results for most use cases.

Is there a file size limit?

You can extract audio from video files up to 2 GB. Since audio extraction only processes the audio stream, it is faster than full video conversion.

Are my files private?

Yes. All processing happens in your browser using FFmpeg WebAssembly. No files are uploaded to any server. Your videos and extracted audio stay entirely on your device.
