Frequently Asked Questions

Everything about converting video to MP3 online.

No. All processing happens entirely inside your browser using WebAssembly. Your video file never leaves your device. This makes it safe to convert private meeting recordings, sensitive interviews, and personal content.

All common video formats are supported: MP4, MOV, MKV, AVI, WEBM, FLV, M4V, 3GP, and more. The tool uses FFmpeg under the hood, which supports virtually every video container format.

The quality depends on the bitrate you choose. At 192 kbps (the default), the extracted audio is indistinguishable from the original video audio for most content. For archiving music videos, 320 kbps is recommended.

Yes. There are no server-side file size limits because everything runs in your browser. Very large files (2 GB+) may take longer and require sufficient device memory, but there is no hard cap.

A video to MP3 converter extracts the audio track from a video file and saves it as a standalone MP3. The video frames are discarded, leaving only the audio at a fraction of the original file size.

The tool will show an error if the output is empty, which typically means the video file has no audio track or the audio is in a format that could not be decoded. Try a different source file.
