Convert AAC to 3GP — Free Online Converter

AAC (Advanced Audio Coding) is the dominant lossy codec for music distribution, used by iTunes, YouTube, and every major streaming platform since its MPEG-2 standardization in 1997. 3GP is a lightweight multimedia container designed by the 3rd Generation Partnership Project for mobile phones operating on 3G networks. Converting AAC to 3GP wraps your audio inside a container that older feature phones and low-bandwidth mobile devices expect, making it possible to send audio clips via MMS or play them on handsets that lack a standalone AAC decoder.

Feature phones from manufacturers like Nokia, Samsung, and LG shipped with native 3GP playback but no raw AAC support. If you need to send a voice memo or music clip to someone on a basic handset, or upload audio to an MMS gateway that only accepts 3GP, this conversion is essential. 3GP also strips unnecessary metadata, producing smaller files suited for constrained storage.
