A video to audio extractor pulls the audio track from a video file so you can use it independently — for podcasts, music, presentations, or archiving. This tool uses the Web Audio API to decode and re-encode audio entirely in your browser, without any upload.

How to Extract Audio from Video
This video to audio extractor uses the Web Audio API to decode the audio track from any browser-compatible video file, then re-encodes it to a downloadable audio file. Everything happens locally — no upload needed.
Step 1: Upload Your Video
Drag and drop your video file into the upload area or click to browse. The tool accepts any video format that your browser supports natively: MP4 (with H.264/AAC), WebM (VP8/VP9 + Opus), and OGG. Once uploaded, you'll see the file details including duration and resolution.
Step 2: Extract the Audio
Click Extract Audio to start the process. The Web Audio API reads the video's audio track, decodes it, and re-encodes it as WebM audio (Opus codec). A progress bar shows the extraction status. For long videos, this may take 10-30 seconds depending on your CPU speed.
Step 3: Preview and Download
After extraction, the audio is shown with a waveform visualization and a built-in audio player so you can verify the content before downloading. Click Download Audio to save the WebM audio file to your device.
Converting to MP3 or Other Formats
The extracted audio is in WebM format. For MP3 conversion, which requires a codec not available in browsers for legal reasons, use free desktop tools: VLC (Media > Convert/Save), Audacity (with FFmpeg plugin), or FFmpeg command-line tool. These tools can convert WebM audio to MP3, FLAC, or any other format you need.
Common Use Cases
Video to audio extraction is useful for: pulling the audio track from a video interview to use as a podcast, extracting music or sound effects from video clips, archiving audio content from video files, and preparing audio for editing in a DAW like Audacity or GarageBand.
FAQ
Is this video to audio extractor really free?
Yes, completely free with no limits. There are no watermarks, no file size caps, and no signup required. All extraction happens in your browser using the Web Audio API.
Is my video data private?
Absolutely. Your video file is never uploaded to any server. All audio extraction happens locally in your browser using the Web Audio API. Once you close the page, all data is gone from memory.
What output format is the extracted audio?
The audio is extracted as WebM audio format (using Opus or Vorbis codec depending on your browser). WebM audio is supported by Chrome, Firefox, Edge, and VLC player. For MP3 output, you would need a desktop tool.
What video formats are supported?
The tool supports video formats your browser can play natively, including MP4 (H.264/AAC), WebM, and OGG. The video must have an audio track for extraction to work.
Will the audio quality be the same as the original?
The audio is decoded from the video and re-encoded to WebM audio format. The output quality depends on the original audio track quality and the re-encoding process. For archival purposes, lossless extraction is better done with desktop tools like FFmpeg.
What if the video has no audio track?
If the video file has no audio track, the extraction will produce an empty or silent file. The tool will notify you if no audio data is detected during processing.
How long does extraction take?
Extraction time depends on the video length and your computer's CPU speed. The audio is decoded in real time using the Web Audio API, so a 5-minute video typically takes 10-30 seconds to extract.
