Why Convert AAC to FLAC?
AAC (Advanced Audio Coding) is a lossy audio format known for good quality at relatively low bitrates. FLAC (Free Lossless Audio Codec), on the other hand, is a lossless format. Converting AAC to FLAC allows you to store your audio in a format that preserves all the original audio data present in the AAC file, without further compression loss. While you cannot regain quality lost during the initial AAC encoding, converting to FLAC ensures no additional quality is lost during this conversion and provides a high-quality archival format.
Benefits of Converting AAC to FLAC
- Lossless Quality: FLAC preserves the exact audio data from the source AAC file without further loss.
- Archival Standard: FLAC is widely used for archiving high-quality audio.
- No Further Degradation: Ensures no additional quality loss compared to converting to another lossy format.
- Open Source: FLAC is an open and royalty-free format.

Note: Converting from a lossy format (AAC) to a lossless format (FLAC) will result in a significantly larger file size, as FLAC stores more audio information. The quality will be identical to the source AAC file, but no better.

Frequently Asked Questions
Does converting AAC to FLAC improve audio quality?
No. Converting from a lossy format like AAC to a lossless format like FLAC cannot restore audio data that was lost during the original AAC encoding. The resulting FLAC file will have the same audio quality as the source AAC file, but it will prevent any further quality loss from re-encoding into another lossy format.
Why is the FLAC file so much larger than the AAC file?
FLAC is a lossless format, meaning it compresses audio without discarding any data. AAC is a lossy format, achieving smaller file sizes by removing some audio information deemed less perceptible. Because FLAC stores all the audio data from the source (even the compressed AAC source), its file size is significantly larger.
