FLAC to M4A (AAC) is lossy and yields a smaller file that's native to Apple devices. Choose a high bitrate to retain detail.
About FLAC
Lossless compressed format
FLAC uses lossless compression, cutting file size roughly in half while keeping the original audio quality. It is widely used by audiophiles and for archiving.
- Lossless, identical to the source
- Much smaller than WAV
- Some older players lack support
About M4A
Common audio container in Apple ecosystem

- Good balance of size and quality
- Native to the Apple ecosystem
- Limited support on some non-Apple players
FLAC to M4A FAQ
Will converting FLAC to M4A lose quality?
Converting lossless FLAC to lossy M4A will introduce quality loss. For best results, choose a higher bitrate in the advanced settings.
Will the file size change after conversion?
Converting to a lossless format (WAV) usually increases size, while converting to a lossy format (MP3, AAC) usually decreases it, depending on the chosen bitrate and sample rate.
How do I batch convert FLAC to M4A?
Just drop multiple FLAC files in; they are converted to M4A one by one via a queue. You can download them individually or as a single ZIP.
