FLAC (.flac) · Max 20 MB
The converter defaults to the highest practical bitrate for MP3. For lossy output, that means 320kbps or VBR quality 0. Transparent quality for virtually all listeners.
Garbage in, garbage out. The output quality depends on your source. A 128kbps FLAC file won't sound better in MP3. Start with the best source available.
AudioUtils processes everything locally using WebAssembly. The encoder runs at near-native speed. A 10-minute file converts in seconds with maximum quality settings.
Frequently Asked Questions
What MP3 bitrate should I use for FLAC conversion?
320kbps for the best quality, 256kbps for a great balance, 192kbps if storage is tight. Avoid going below 192kbps — the quality drop becomes noticeable.
How much smaller will the MP3 be?
Dramatically smaller. A 30MB FLAC file becomes roughly 5-7MB as MP3 at 320kbps. That's a 75-80% size reduction.
Will the conversion preserve metadata?
The converter preserves basic metadata like title, artist, and album when possible. Cover art may not transfer in all cases.
Can I batch convert multiple FLAC files?
Free users can convert one file at a time. Pro users get batch conversion support for processing entire albums or libraries at once.
