How do I convert AIFF files to MP4?

Choose AIFF files, select MP4 as the output format, and adjust video settings like resolution or bitrate if needed. Click 'Convert' to start the batch conversion. Once finished, download the MP4 files with your audio embedded.

Why should I convert AIFF to MP4?

AIFF is an uncompressed audio format used in professional audio editing, but it's not widely supported by media players and social platforms. MP4 with AAC audio compresses the file while preserving good quality, making it easier to upload, share, and play on devices and software that don't support AIFF.

What happens to audio quality and metadata when converting AIFF to MP4?

The audio from AIFF is re-encoded to AAC codec within the MP4 container. If your AIFF file is 24-bit/96kHz, you can choose to preserve the sample rate up to the container's maximum, but note that MP4 typically supports up to 24-bit/48kHz for wide compatibility. The video track is generated as a static or customizable image (like a cover art) to create a video file. No color profiles or layers apply since AIFF is audio-only.
