Convert AIFF to 3GP — Free Online Converter

AIFF (Audio Interchange File Format) is Apple's uncompressed audio format from 1988, storing PCM audio at full CD quality — 16-bit, 44.1 kHz, roughly 10 MB per minute. 3GP is a lightweight multimedia container built for 3G mobile networks, typically carrying AMR narrowband speech audio. Converting AIFF to 3GP compresses studio-quality audio down to mobile-friendly sizes, enabling delivery over constrained cellular connections to feature phones and legacy handsets.

AIFF files are enormous compared to what 3G-era mobile infrastructure can handle. A one-minute AIFF clip at CD quality is about 10 MB, while a one-minute AMR-NB file is under 100 KB. When you need to deliver voice content to legacy telecom systems — MMS gateways, voicemail servers, IVR platforms — 3GP with AMR encoding is the required format. Feature phones from Nokia, Samsung, and Sony Ericsson accept 3GP natively.
