How do I convert RMVB to MP3 using this tool?

1) Click 'Upload' and select a .rmvb file. 2) Choose output settings: format MP3, bitrate (e.g., 192 kbps). 3) Click 'Convert'. 4) Download the resulting MP3 to your device. The RMVB's video track is discarded, only audio is processed.

Why convert RMVB to MP3 instead of keeping the original?

RMVB is a container used mainly by RealPlayer and may include video; MP3 is an audio-only codec supported by virtually every player, phone, and editor. Converting to MP3 lets you play a song or podcast from an RMVB on any device, and cuts file size significantly—for example, a 3-minute track encoded at 128 kbps is roughly 2.8 MB, regardless of the original RMVB size.

What happens to the audio quality and metadata during RMVB to MP3 conversion?

The RMVB's audio is decoded into raw PCM, then re-encoded with MP3's lossy compression. If you choose 320 kbps, the output preserves most audible detail; at 128 kbps, higher frequencies are cut to save space. Metadata such as artist and title is copied if present. Any video data (resolution, HDR, or subtitles) is ignored because MP3 cannot contain video streams.
