How to convert WAV to MP3

  1. Upload your WAV file (up to 50 MB).
  2. Choose a bitrate (192, 256, or 320 kbps).
  3. Click 'Convert WAV to MP3' — takes 5-15 seconds.
  4. Download the MP3.

Quick fact about WAV

WAV files are uncompressed — a 4-minute song can be 40+ MB. Converting to MP3 at 320 kbps reduces size by 90% with no audible quality loss for most listeners.

Why convert WAV to MP3?

WAV is uncompressed — it preserves every sample of the original recording, which makes files huge (a 4-minute song can be 40+ MB). For playback on phones, streaming, and casual listening, MP3 at 320 kbps is virtually indistinguishable from the WAV source while being 90% smaller.

Technical details

Input format WAV (uncompressed PCM)
Output format MP3
Bitrate range 192-320 kbps
Default bitrate 320 kbps (transparent)
Encoder LAME
Sample rate Preserved
Channels Preserved (mono/stereo)
Typical size reduction ~90%
Max file size 50 MB per file
File retention Auto-deleted after conversion

How the conversion works

The converter decodes the WAV (PCM) audio and re-encodes it as MP3 using LAME. At 320 kbps, the conversion is transparent for almost all listeners. Metadata is preserved.

When to convert WAV to MP3

Quality considerations

At 320 kbps, MP3 is transparent for almost all listeners — you won't hear the difference from the WAV original. At 192 kbps, it's transparent for casual listening. For audiophile-critical work, keep the WAV.

Tips for best results

Common problems and fixes

Audio quality is slightly worse
Use 320 kbps for best quality. Lossy→uncompressed conversion is always slightly lossy.
24-bit WAV loses precision
24-bit is downsampled to 16-bit for MP3 compatibility. Keep the original for 24-bit work.
Multi-channel WAV loses channels
Multi-channel is downmixed to stereo. For 5.1 or 7.1, keep the original.
