Good to know
- The MP3 is encoded at 192 kbps constant bitrate from the first audio track of the video.
- The sample rate is your device's playback rate, usually 44.1 or 48 kHz; surround sound is mixed down to stereo.
- MP3 is a lossy format, so the result is smaller than the original sound but not identical to it.
- The file is named after your video with _converted.mp3 at the end.

Frequently Asked Questions
What video formats are supported?
The converter accepts MP4, MOV, WebM, MKV, AVI and other video files, up to 500MB. If a video has several audio tracks, the first one is converted.
What is the audio quality of the output?
The output is a standard 192 kbps MP3, which plays on any phone, car stereo, or media player.
Can I convert only a portion of the video?
Currently the tool converts the entire video. For partial extraction, we recommend first trimming your video using a video editor and then converting the trimmed clip to MP3.
Tips & Best Practices
- Use MP4 for best results: MP4 files with AAC audio provide the most reliable extraction across all browsers and operating systems.
- Check the preview: Always listen to the audio preview before downloading to verify the quality and completeness of the extraction.
- Shorter clips convert faster: If you only need a portion of the audio, trim the video first to reduce conversion time significantly.
- Use an up-to-date browser: Current versions of Chrome, Edge, Firefox and Safari read the same range of video files.
- Mind the file size: While 500MB videos are supported, smaller files convert faster and the resulting audio files are more manageable.
