## Frequently asked questions

### What is the difference between FLAC and AAC?

FLAC is a lossless format that preserves all original audio data, while AAC is a lossy format designed for high-quality audio compression and smaller file sizes.

### Can I convert multiple files at once?

This tool is designed to process one audio file at a time.

### Will I lose audio quality during conversion?

Because AAC is a compressed format, there is a slight reduction in data compared to the original FLAC, but choosing a higher bitrate like 320 kbps minimizes audible differences.

### Does this tool support metadata preservation?

Yes, you can enable the 'Keep Metadata' checkbox to retain title, artist, and album information from the original file.

### What is the maximum file size I can upload?

You can upload FLAC files up to 80 MB in size.
