Convert FLAC to AAC NowAbout FLAC (Free Lossless Audio Codec)
Lossless compression: identical audio quality to WAV at roughly half the file size. FLAC is the go-to for archiving music collections and delivering masters, and it's the required upload format for several distribution platforms. It supports embedded metadata and album art, which WAV handles poorly.
Best for: archiving, music distribution, audiophile listening
About AAC (Advanced Audio Coding)
The successor to MP3, delivering noticeably better quality at the same bitrate — especially below 192 kbps. AAC is the native format of the Apple ecosystem (iTunes, Apple Music, iPhone) and the standard audio codec inside YouTube videos and most streaming services.
Best for: Apple devices, YouTube, streaming, small high-quality files

FLAC vs AAC: what changes?
FLAC is a lossless format, while AAC is lossy. Converting to AAC compresses the audio to a much smaller file. Choose a high bitrate (192-320 kbps) to keep the difference inaudible.
