Frequently Asked Questions

How does the MP4 to MP3 converter work?

Our converter uses Remotion (remotion.dev) directly in your browser. When you upload an MP4 file, it extracts the audio track locally on your device and saves it as an MP3 file without ever being sent to a server.

Is there a file size limit?

Yes, currently we limit file sizes to 500MB to ensure smooth performance in the browser. For larger files, you might need to use a desktop application.

Will this affect the audio quality?

Our converter extracts the audio at a high bitrate of 192kbps, which maintains excellent quality while keeping file sizes reasonable.
