Change MP3 Bitrate — Compress or Increase Bitrate for Compatibility or Exporting Purposes
Re-encode MP3 files at a different bitrate to reduce file size or standardize quality. Choose from common bitrates like 128, 192, 256, or 320 kbps. Note: Increasing bitrate does not restore lost audio quality from previously compressed files.
Perfect for shrinking podcast episodes for smaller files, normalizing a music library to a consistent bitrate, or meeting file size limits on platforms. The conversion runs entirely in your browser.
