What this conversion does

What to know

  • Processing takes place in your browser; the selected files are not uploaded.
  • Features that the target format cannot represent may be flattened, simplified or omitted.
  • Encoding depends on browser support. The output container and profile may vary.
  • Lossy conversion can reduce quality further. Metadata may be omitted.
  • Compare the exported sound with the original. A larger bitrate cannot restore detail already lost, and codec availability depends on the browser.
