WAV to MP3 Converter

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.

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.

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.

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.

• Converting WAV music for phones and portable players.
• Reducing storage for a WAV-heavy library.
• Sharing WAV recordings with people who only support MP3.
• Preparing WAV files for streaming services.
• Converting audio production exports to MP3.
• Reducing backup size for a WAV archive.
• Fitting more audio on a phone or SD card.

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.

• Conversion is lossy — MP3 can't be reverted to WAV losslessly.
• 24-bit WAV is downsampled to 16-bit.
• Multi-channel WAV is downmixed to stereo.
• File size reduction is ~90%, not more.
• Very large WAV files may take longer.

• Output MP3 plays on every device, player, and OS.
• Works with iTunes, Windows Media Player, VLC, phones, car stereos.
• ID3 tags preserved.
• Standard MP3 — no special software needed.
• Accepted by every audio platform.

• 320 kbps is best for critical music listening.
• 192 kbps is transparent for casual listening.
• Metadata is preserved.
• Keep the original WAV if you may want lossless later.
• For audiophile work, keep the WAV — don't convert.

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.
