This tool extracts the audio track from a video file and saves it as a standalone MP3 file. Upload a video, and download just its sound — useful for turning a video's soundtrack, narration, or dialogue into an audio file you can use on its own.
Processing happens entirely in your browser using a built-in video processing engine — your video is never uploaded to a server. The first time you use any of our video tools, there's a one-time download of this processing engine (around 30MB), cached afterward for instant use.
This tool extracts a copy of the audio track — your original video file is not modified. The output is a separate MP3 file containing only the audio, while your video remains intact on your device exactly as it was.
Video files store their audio in a variety of formats depending on how they were created — AAC is common in MP4 files, Opus or Vorbis in WebM files, and various others depending on the source. Rather than producing a file in whichever format happens to be embedded in your specific video (which would vary unpredictably from file to file), this tool re-encodes the extracted audio to MP3 — a format that's universally supported by every media player, phone, car stereo, and audio editing tool. The trade-off is a small amount of re-encoding, but at the bitrate used here, this is generally not noticeable for spoken content and is a reasonable trade for guaranteed compatibility.
If you specifically need a lossless copy of the original audio stream without any re-encoding, that would require a different extraction approach that preserves the container's native audio codec — but for the vast majority of use cases (podcasts, narration, transcription, casual listening), the MP3 output from this tool is the more practical and widely usable choice.
One of the most common reasons to extract audio from video is to prepare it for transcription. While our Audio & Video to Text tool can work directly with video files, there are a few reasons you might extract the audio first: if you're using a third-party transcription service that only accepts audio files, if you want to keep a smaller audio-only archive of a recording's spoken content separately from the (often much larger) video file, or if you want to listen back to just the audio to check transcription accuracy without needing to play the video.
If your video is a long recording — a webinar, a recorded meeting, a multi-hour stream — and you only need the audio from a specific portion, it's often more efficient to trim the video down first using our Video Trimmer before extracting audio. This reduces the amount of data that needs to be processed and results in a smaller, more focused audio file rather than extracting the audio from the entire recording and then trimming the audio afterward.
Once you have the audio file, you can trim it to a specific section using Audio Trimmer, compress it further with Audio Compressor, or transcribe it to text with Audio to Text.
The extracted audio is saved as an MP3 file, which is widely compatible with media players and other audio tools.
No, this extracts a copy of the audio track. Your original video file remains unchanged on your device.
Common formats including MP4, WebM and MOV are supported as input.
Files up to 100MB are supported. Larger files take longer to process since everything runs in your browser.
No, processing happens entirely within your browser.
