Extract Audio

Extract Audio pulls the audio track from any video file and saves it as MP3, WAV, or AAC. Whether you need the soundtrack from a presentation recording, the dialogue from an interview video, or the music from a concert recording, this tool separates the audio stream and exports it as a standalone audio file — all within your browser with no server uploads. Video files contain both a video stream and an audio stream bundled together. Many use cases only need the audio portion: converting a lecture recording to a podcast-style audio file for commuter listening, extracting the soundtrack from a video for use in another project, or saving the audio from a recorded meeting for transcription. Rather than playing the entire video to hear the audio, extracting the track gives you a portable audio file that works in any music player or audio editor. The extraction uses FFmpeg compiled to WebAssembly, running entirely in your browser. The video file is decoded locally, the audio stream is isolated, re-encoded into your chosen format, and presented for download. The original video file is never transmitted anywhere.

Upload any video file containing an audio track. Select the output format: MP3 (broad compatibility, good compression), WAV (uncompressed, highest quality), or AAC (efficient compression with good quality for Apple devices). Optionally adjust the audio bitrate — higher values produce better quality but larger files. For MP3 output, you can choose between mono and stereo mode. Mono is sufficient for voice-only content and produces smaller files. The tool displays the estimated output size based on your settings. Once you click Extract, the tool processes the audio and offers it for download as a standalone audio file with a preview player so you can verify the result before closing the page.

Video-based audio is everywhere. Students record lectures on their phones and want to listen while commuting without the video draining battery. Journalists record interviews as video for backup but only need the audio for transcription. Content creators repurpose video content into podcast episodes or audio snippets for social media. Extracting the audio track is the first step in all of these workflows.
