What happens when you convert FLAC to AAC
| Compression | Lossless → Lossy |
|---|---|
| Size per minute | FLAC ≈ 6.4 MB → AAC ≈ 1.4 MB at 192 kbps |
| Quality | Lossy encode; 192 kbps is transparent for most listeners, 128 kbps is fine for speech |
| Tags | Title, artist and album tags are copied when the target format supports them |
| Opens in | phones, browsers and most players; some editors want it inside M4A |
Sizes are typical values; your files will vary with content and settings.
FLAC Free Lossless Audio Codec
FLAC compresses audio losslessly to around 50 to 60 percent of WAV size. Decoding gives back the exact original samples, so it is the format of choice for archiving music.
FLAC converterAAC Advanced Audio Coding
AAC is the successor to MP3 and the audio codec inside most MP4 videos, YouTube and Apple Music. A raw .aac file is an ADTS stream without a container.

FLAC files come from CD rips and lossless music stores such as Bandcamp and Qobuz. Files are much larger than MP3 and some portable players cannot play them. Choose AAC when a player, hardware device or editor expects a raw AAC stream.
Frequently asked questions
Will the AAC lose quality?
AAC uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the FLAC original.
Will the AAC be smaller than the FLAC?
Usually yes: a minute of audio takes about 6.4 MB as FLAC and about 1.4 MB as AAC at 192 kbps. Lower the bitrate to shrink it further; 128 kbps is plenty for speech.
