Free Video to MP3 Converter: Extract Audio from Any Video
The converter pulls the audio track out of MP4, MOV, MKV, AVI, WEBM, and other video files (up to 2 GB) and saves it as an MP3 at up to 320 kbps. It takes video files only — pasted YouTube or other links don't work, by design. Convert in your browser and download. No upload, no account, no watermark.
