Convert your FLAC audio files to AAC (Advanced Audio Coding) format using our free online tool. AAC provides excellent audio quality at smaller file sizes, making it ideal for portable devices, streaming, and when storage space is limited. No Signup Required.
FLAC (Free Lossless Audio Codec) is an open source lossless audio format that offers exact audio reproduction while reducing file size by about 50-60% compared to uncompressed audio.
AAC (Advanced Audio Coding) is a lossy audio codec designed to be the successor to MP3, offering better sound quality at the same bitrate or similar quality at lower bitrates.
While FLAC preserves 100% of the original audio data, AAC uses perceptual coding techniques to remove audio information that is less noticeable to human hearing, resulting in smaller file sizes.
AAC is widely supported across platforms including iOS, Android, Windows, and macOS, making it an excellent choice for portable devices and streaming services.
Converting FLAC to AAC involves transcoding from a lossless to a lossy audio codec. The conversion decodes the FLAC file to uncompressed PCM audio and then encodes it to AAC format.
AAC files are typically 5-10 times smaller than the original FLAC files, making them much more practical for portable devices with limited storage.
AAC can be encoded at various bitrates, with higher bitrates (256kbps+) providing nearly transparent audio quality for most listeners.
This conversion is especially useful for creating portable versions of your high-quality music collection while maintaining good sound quality.
AAC supports multichannel audio and high sampling rates, making it suitable for a wide range of audio content from music to podcasts.
Pro Tip: Converting from FLAC to AAC is ideal for creating portable versions of your music library. Choose a higher bitrate (256kbps or higher) when converting to AAC to maintain excellent audio quality while still benefiting from significantly reduced file sizes.
