Frequently Asked Questions
Why convert FLAC to MP3?
FLAC is a lossless audio format that preserves full quality but creates large files (30-50 MB per song). MP3 files are 60-80% smaller and play on virtually every device, app, and music player. For everyday listening, most people cannot tell the difference between a 320kbps MP3 and the original FLAC.
What bitrate should I use for FLAC to MP3?
320kbps is the best choice if you want the closest quality to your FLAC originals. 192kbps offers a good balance between quality and size for music. 128kbps works fine for podcasts, voice recordings, or when storage space matters most. Read our FLAC to MP3 conversion guide for more details.
Will I lose audio quality converting FLAC to MP3?
Yes, some quality is lost because MP3 is a lossy format while FLAC is lossless. However, at 320kbps the difference is minimal and inaudible to most listeners on standard headphones and speakers. Your original FLAC files remain unchanged.
Are my files uploaded to a server?
No. All conversion happens in your browser using WebAssembly (FFmpeg compiled for the web). Your FLAC files never leave your device. Nothing is uploaded, stored, or tracked. Learn more on our security page.
How much smaller will my files be?
A typical 30 MB FLAC file becomes about 7-10 MB as a 320kbps MP3, or 4-6 MB at 192kbps. The exact reduction depends on the audio content and bitrate you choose. Check our FLAC vs MP3 comparison for detailed size examples.
