Convert 3GA to iPhone Audio — Free Online Converter

The iPhone Audio preset converts 3GA recordings from old Android and feature phones into the optimal format for all iPhone models. The preset outputs an M4A file encoded with AAC-LC at 256 kbps and 44.1 kHz sample rate — the same codec and quality level Apple uses for iTunes Store music purchases. iPhones have zero support for the .3ga extension, so this conversion is essential for anyone who switched from a Samsung, Nokia, or LG phone to iPhone and wants to access their old voice recordings.

Every iPhone ever made, from the original 2007 model to the latest iPhone 16 Pro Max, supports AAC in M4A natively. The converted file integrates with the Music app, Voice Memos, iMessage, FaceTime, GarageBand, and every other Apple audio workflow. Unlike generic MP3 conversion, the iPhone Audio preset produces a file specifically optimized for Apple's hardware audio decoder and the AAC-LC profile that iPhones handle with maximum efficiency and minimum battery drain.

When users migrate from an older Android phone or feature phone to iPhone, 3GA recordings are among the files that become completely inaccessible. The iPhone's Files app cannot preview them, Safari cannot play them, and no native Apple app recognizes the .3ga extension or the AMR codec stored inside. Converting to the iPhone Audio preset immediately makes these recordings first-class citizens in the iOS ecosystem.

The 256 kbps AAC at 44.1 kHz is Apple's gold standard for distributed audio. It is the exact format used by the iTunes Store, Apple Podcasts imports, and GarageBand exports on iOS. By matching these specifications, the converted file behaves identically to any audio purchased or recorded natively on the iPhone. Metadata, artwork, and chapter markers are fully supported in the M4A container, so you can organize your converted recordings in the Music app alongside your regular library.
