How do I convert M4A to AIFF using LetsConvert?

1. Upload your M4A file. 2. Select AIFF as the output format. 3. Optionally adjust sample rate and bit depth. 4. Click Convert and download the AIFF file. The conversion repackages audio into uncompressed PCM while preserving sample rate and channel count.

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

AIFF is an uncompressed audio format widely supported by digital audio workstations (DAWs), video editing software, and legacy Apple/Mac systems. M4A typically uses AAC lossy compression, which discards audio data to reduce file size. Converting to AIFF ensures bit-perfect audio for editing, archiving, and professional tool compatibility—trading larger file sizes for uncompromised fidelity.

What happens to bitrate, sample rate, and metadata when converting M4A to AIFF?

M4A (AAC) stores audio at a specific bitrate and sample rate; AIFF stores audio as uncompressed PCM. During conversion, the audio is decoded to raw PCM, retaining the original sample rate (e.g., 44.1 kHz) and bit depth (e.g., 16-bit). The bitrate becomes a function of these values (e.g., 1411 kbps for CD quality), not the original lossy bitrate. Metadata tags are usually preserved, but cover art may not be supported by all AIFF players and could be dropped.
