Extract audio from video online free with FreeToolBox — pull the audio track from any MP4, MOV, WebM, or AVI file and save it as MP3, AAC, or WAV right in your browser. Extracting audio from video is useful for creating podcasts from video recordings, isolating a song from a music video, saving lecture audio, or creating ringtones from video clips. Our tool uses FFmpeg.wasm to extract the audio track while preserving original quality.
All processing happens locally in your browser using WebAssembly — your video is never uploaded to any server. The extracted audio has no watermarks. Completely free, no account required.
MP3 (widely compatible, smaller files), AAC (high quality, used by Apple devices), WAV (lossless, larger files, best for audio editing), and OGG (open source, good for web use).
If the original video's audio codec matches the output format, the audio is copied directly without re-encoding, preserving perfect quality. Converting between formats involves a minor re-encoding step.
The tool will notify you if no audio track is detected. Silent videos (muted recordings, screen recordings without system audio) have no audio to extract.
No. FFmpeg.wasm extracts your audio entirely within the browser. Your video file stays on your device and is never transmitted anywhere.
