How to use

  1. Choose an audio file.
  2. Select MP3 quality.
  3. Convert and download the new MP3.

What this tool does

Turn WAV, M4A, AAC, FLAC, OGG, OPUS and other compatible audio files into a widely supported MP3.

Worked example

Ten minutes of speech at 128 kbit/s takes roughly 600 × 128 ÷ 8 = 9600 kB, about 9.6 decimal MB plus small metadata. This estimate helps you decide whether a lower bitrate is worthwhile.

Limits that affect the result

Choosing 320 kbit/s cannot restore a poor recording. MP3 is lossy; keep a lossless source for later editing.
