FLAC (.flac) · Max 20 MB
Traditional online converters upload your file, process it on a remote server, and send it back. That's slow, insecure, and wasteful. AudioUtils eliminates the upload entirely.
The converter uses WebAssembly to run a compiled audio engine in your browser tab. It reads your file locally, converts it locally, and saves the result locally. The network is never involved.
This matters for sensitive audio. Unreleased music, legal recordings, private conversations. With AudioUtils, your files stay yours. FLAC is lossless. Converting to MP3 reduces file size at the cost of some audio data. Use a high bitrate to minimize loss.
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.
