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.
This process runs entirely on your device — no server is involved.
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?
No. The entire process runs in your browser using the Web Audio API.
Your video file never leaves your device. No servers, no storage, no tracking.
This makes it safe for private videos, confidential recordings, or copyrighted 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.
