How do I convert a WAV file to M4A with LetsConvert?

Go to the WAV to M4A converter, upload your WAV file, select M4A as the target format, and choose your preferred AAC bitrate (e.g., 256 kbps). Click Convert, then download the resulting M4A. You can convert multiple WAV files at once with the batch option.

Why should I convert WAV to M4A instead of keeping WAV?

WAV files are uncompressed and can be 5–10 times larger than M4A. M4A uses AAC encoding, which produces near-CD quality at a fraction of the size, making it perfect for iPhones, Android, and web uploads. However, if you need lossless editing, keep WAV.

What happens to audio quality when converting WAV to M4A?

The WAV's uncompressed PCM stream is decoded and re-encoded into AAC. Sample rate and channel count (e.g., 48 kHz stereo) are preserved, but the encoding drops some audio data—especially above 16–20 kHz. At 320 kbps, the difference is hard to hear, but it remains a lossy copy, not a bit-perfect transcode.
