Video to Audio Features
Audio extraction with format and bitrate controls.
Supported Video Formats
Supports MP4, MOV, AVI, WebM, MKV and other common video formats.
Extracts audio and encodes to MP3 with your chosen bitrate.
Browser-side processing can keep your video on your device when supported.
Privacy & Performance
Your video stays on your device. browser-side workflows happens in the browser.
Choose from 64 to 320 kbps to balance file size and audio quality.
Works on any modern desktop or mobile browser with no software to install.
Key Takeaways
- Audio extraction runs entirely in your browser, so the video file is processed on your device, which makes it safe for confidential meetings and personal recordings.
- It outputs a single MP3 of the complete soundtrack from a video file you already have saved; it cannot fetch or download videos from streaming sites or links.
- Use the bitrate slider to match your source: around 128 kbps for podcasts and speech, the 192 kbps default for mixed audio, and up to 320 kbps for music you want to keep detailed.
- Extraction relies on your browser's built-in codecs, so MP4 and WebM work widely; if a file (often MKV or AVI) will not decode, convert it to MP4 first, and use a desktop browser for large files since the whole video is decoded in memory.
How to Extract Audio from a Video in Your Browser
Add your video file
Drag a video onto the upload area or click Choose Video File to pick one from your device. The file is read locally on your device, so even large clips stay on your computer.
Set the bitrate
Move the bitrate slider to balance quality against file size. Lower values such as 128 kbps suit speech and podcasts, while higher values up to 320 kbps preserve more detail for music.
Extract and download
Click Extract Audio. The browser decodes the video, renders the full audio track, and encodes it in real time. When it finishes, download the resulting MP3 file with the original name.
Bitrate Settings and What They Are Good For
The bitrate slider controls how much data per second is kept in the extracted audio. Higher bitrates sound better but produce larger files. Use this table to pick the right setting for your source material.
| Bitrate | Best for | Relative file size | Quality |
|---|---|---|---|
| 64 kbps | Voice memos, audiobooks, mono speech | Smallest | Basic, intelligible voice |
| 96 kbps | Spoken word, lectures, low-bandwidth sharing | Very small | Clear speech |
| 128 kbps | Podcasts, interviews, general use | Small | Good for talk content |
| 192 kbps | All-purpose default for mixed audio | Moderate | Very good |
| 256 kbps | Music with detail you want to keep | Larger | High |
| 320 kbps | Music extraction, archival copies | Largest | Highest available |
Is This the Right Tool for Your Job
You have the video file on hand
This tool works on video files already saved to your device, such as recordings, downloads, or exports. It does not fetch or download videos from streaming sites or links.
You want the complete soundtrack
The extractor captures the entire audio track from start to finish. If you only need a portion, extract first and then use a separate audio trimmer to cut the part you want.
Privacy matters for your footage
Because decoding and encoding happen in your browser, the video stays on your machine. This suits confidential meetings, personal recordings, or material you cannot upload.
Your browser can decode the format
Extraction relies on your browser built-in codecs. Common formats like MP4 and WebM work widely. If a file will not decode, convert it to MP4 first, then extract the audio.
Common Problems and Fixes
Could not decode audio from this video
Your browser may not support the codec inside the file. This is common with some MKV or AVI containers. Convert the video to MP4 with our video converter first, then run the extraction again.
Extraction is slow on a large file
The whole video is decoded in memory, so long or high-resolution files take longer and use more RAM. Use a desktop browser for big files and close other heavy tabs to free up memory.
The output file is silent
If the source video has no audio track, the result will be empty. Confirm the video actually plays sound, and check that the correct file was selected before extracting.
Drag and drop does nothing
The drop area only accepts files the browser recognizes as video. If your file is not detected, use the Choose Video File button instead, which lets you pick the file directly.
Why Extract Audio from Video?
Videos often contain useful audio, including music, speeches, podcasts, or sound effects, that you may want as a standalone audio file. This tool extracts the audio track and saves it as MP3, with processing behavior depending on browser support and file size.
Frequently Asked Questions
Which video formats work?
The tool supports any video format your browser can decode, which includes MP4 (H.264/H.265), WebM, MOV, and AVI on most modern browsers.
MKV and other container formats work if your browser supports the codec inside.
If a format is not supported, try converting the video to MP4 first using our video converter.
How is the audio extracted?
The browser decodes the video using its built-in video element, then the Web Audio API captures the audio stream.
MediaRecorder encodes the stream to compressed audio and saves it as a downloadable file.
When browser-side processing is supported, the workflow can run on your device.
Is this the same as YouTube to MP3?
No. This tool works with video files you already have on your device, not online videos.
To extract audio from an online video, you would need to download the video first.
Always respect copyright when extracting audio from video content.
What bitrate should I choose?
128 kbps is ideal for voice recordings, podcasts, and audiobooks where file size matters.
192 kbps is the best all-purpose setting — excellent quality and reasonable file size.
320 kbps is for music extraction where you want the highest possible audio quality.
Is my video uploaded anywhere?
The tool is designed for browser-side extraction when supported by the file and browser.
For sensitive videos, confirm the active workflow before processing.
Always respect copyright when extracting audio from video content.
How long does it take?
Processing time depends on video length and your device speed. A 5-minute video typically takes 10-30 seconds.
Larger or longer videos take proportionally more time as the browser decodes the full video.
For very large files (over 1GB), a desktop browser will perform better than mobile.
Does it work on iPhone and Android?
Yes, modern mobile browsers support the Web Audio API used by this tool.
On iOS, Safari provides the best compatibility. On Android, Chrome works best.
Mobile processing is slower than desktop for large files, but works fine for shorter videos.
Can I extract audio from a recorded screen?
Yes. Screen recordings saved as MP4 or WebM work perfectly with this tool.
This is useful for extracting audio from recorded meetings, webinars, or tutorials.
The output will include all audio that was captured in the screen recording.
