WAV to MP3: smaller files for sharing and players

WAV is what DAWs, recorders and sample packs produce: uncompressed PCM, large and readable almost anywhere. MP3 is how a mix, a demo or a field recording travels by email, chat or upload, and how it fits onto a phone or a USB stick.

The WAV is decoded on your device and its full-precision samples are encoded at a constant 128, 192, 256 or 320 kbps, or at V0. A five-minute 44.1 kHz stereo WAV of about 53 MB becomes about 12 MB at 320 kbps and under 5 MB at 128 kbps. WAVs at 44.1 or 48 kHz keep their rate; 88.2 and 176.4 kHz files are resampled to 44.1 kHz, 96 and 192 kHz files to 48 kHz. A WAV of three to eight channels is folded to stereo with the standard speaker downmix, LFE left out.

Loops need care: the encoder delays the start and pads the end. The MP3's gapless header records both, so a player that reads it trims them; one that ignores it adds a short gap. Keep loops and stems as WAV. The input limit is 30 minutes, and the WAV must fit your device's memory once decoded: a long 24-bit or 96 kHz recording reaches that limit first, sooner on a phone or tablet.

Frequently Asked Questions

Is WAV or MP3 better quality?
WAV is lossless and MP3 is lossy. Converting will reduce file size significantly, but some audio detail is permanently removed during compression. Use 320 kbps for the best quality.
Will I lose quality converting WAV to MP3?
Yes — converting from lossless WAV to lossy MP3 removes some audio detail. At 320 kbps the difference is inaudible to most people. If you need perfect fidelity, keep the WAV original.
How long does conversion take?
Seconds for most files. Conversion runs entirely on your device — no upload wait, no server queue. Files up to 30 minutes long are supported.
Which bitrate should I pick?
320 kbps, the default, for music you will listen to closely; 192 or 256 kbps for everyday listening; 128 kbps for speech or quick previews where size matters more than detail.
Will my loop stay seamless as an MP3?
Only in a player that reads its gapless header. The encoder adds about 1,100 samples of delay at the start (25 ms at 44.1 kHz) and pads the last frame; the header tells such a player how much to trim. Other players play that silence. Keep loops as WAV.
Which WAV files can it read?
Uncompressed PCM at 8, 16, 24 or 32 bits and 32- or 64-bit float, mono, stereo or multichannel. Compressed WAV variants such as IMA-ADPCM may be refused.
