How do I convert IFF audio to M4A using LetsConvert?

Upload your IFF file by dragging it into the converter. Select M4A as the output format, then choose a bitrate like 192 kbps for balanced quality and size. Click 'Convert' and wait a few seconds. Download the resulting M4A file to your device.

Why convert IFF to M4A instead of keeping the original file?

IFF audio files (often from AIFF) are uncompressed and can be enormous. M4A uses AAC compression to reduce file size by up to 90% while maintaining excellent fidelity for typical listening. M4A also works across iPhones, Android, Windows, and web browsers, while IFF support is limited to niche audio software.

Will converting IFF to M4A lose the original audio quality?

Converting IFF's uncompressed PCM to M4A's lossy AAC does reduce the file's bitrate, which discards some high-frequency detail inaudible to most ears. However, sample rate is preserved, and with a higher bitrate setting (256 kbps) the perceptible quality loss becomes nearly negligible. Metadata like tags and album art are also retained during conversion.
