What does MP4 to MP3 conversion do?

MP4 to MP3 conversion extracts the audio track from an MP4 video and saves it as an MP3 file. This removes the video portion so the file is smaller and easier to listen to.

Will the MP3 have the same length as the MP4?

Yes. The audio duration stays the same. The conversion removes video and changes format, but keeps the timeline intact.

Does converting to MP3 reduce audio quality?

MP3 is compressed audio, so quality depends on source and encoding settings. GhostConvert uses balanced settings intended for clear everyday listening with reasonable file sizes.
