Android has natively supported FLAC since version 3.1 (Honeycomb, 2011), so in many cases you do not need to convert at all. However, 'Android Audio' as a conversion target typically means AAC or MP3 in settings optimized for Android device playback — specifically tuned bitrates, sample rates, and container formats that ensure smooth performance across the fragmented Android hardware landscape, from budget phones with limited DACs to flagship devices with high-resolution audio support.
While FLAC plays natively on Android, there are practical reasons to convert. FLAC files are 2-3x larger than equivalent AAC files, consuming limited internal storage on budget devices. Bluetooth audio on Android transcodes to SBC, AAC, or LDAC anyway — sending FLAC over Bluetooth gains nothing. Battery life is marginally affected by FLAC decoding on older SoCs. And some Android Auto head units handle AAC/MP3 more reliably than FLAC for album art display and track transitions.
The conversion decodes FLAC to PCM and encodes to AAC-LC (the most universally supported Android audio codec) in an M4A container, or to MP3 for maximum compatibility with every Android music player. Default settings target 256 kbps AAC VBR or 320 kbps MP3 CBR. Sample rate is preserved up to 48 kHz (Android's standard output rate on most devices). For devices supporting high-resolution output, 24-bit FLAC can be converted to AAC at higher sample rates.
At 256 kbps AAC or 320 kbps MP3, quality is excellent for portable listening through both wired earbuds and Bluetooth headphones. The difference from the original FLAC is inaudible to most listeners in typical mobile listening environments (commuting, exercising, walking). On high-end wired headphones in a quiet room, trained listeners may detect subtle differences below 256 kbps AAC.

For most Android users, converting FLAC to optimized Android Audio (AAC or MP3) saves significant storage space with negligible quality impact. Keep FLAC originals as your master archive and sync converted files to your device.
