Audio Quality Changer

Adjust bitrate, sample rate, and channel mode to change quality and file size

Drag & drop an audio file or click to browse

How to change audio quality:

  1. Select an audio file (MP3, WAV, OGG, M4A, FLAC, etc.)
  2. Adjust quality settings in the panel on the right:
    • Bitrate – higher = better quality, larger file (32–320 kbps)
    • Sample rate – higher = more high frequencies, larger file
    • Channel mode – Stereo (original) or Mono (smaller file)
  3. Click "Apply Quality & Export" – the file will be re‑encoded
  4. Download the new MP3 and compare quality/size
