Audio Quality

Compresto uses the highest quality VBR (Variable Bit Rate) encoding via the libmp3lame encoder. This produces MP3 files with excellent audio fidelity while keeping file sizes efficient.

Tips

  • Source audio required: The video must contain an audio track. Videos with no audio will produce an empty or invalid file.
  • Supported inputs: Works with any video format Compresto supports — MP4, MOV, WebM, MKV, etc.
  • File size: The output MP3 size depends on the audio duration and complexity, not the video resolution or size.
  • Batch extraction: You can extract audio from multiple videos at once — each will produce a separate MP3 file.
