About This Tool
FLAC (Free Lossless Audio Codec) preserves every detail of the original recording with zero quality loss, but produces large files — often 3 to 5 times bigger than MP3. MP3 uses lossy compression to dramatically reduce file size while retaining perceptually excellent audio quality. Converting FLAC to MP3 is ideal when you need smaller files for portable devices, streaming, or sharing, and don't require studio-grade fidelity. All processing happens directly in your browser using WebAssembly technology — your audio files are never uploaded to any server.
Frequently Asked Questions
What is the difference between FLAC and MP3?
FLAC is a lossless format that preserves 100% of the original audio data, resulting in larger files. MP3 is a lossy format that removes inaudible frequencies to achieve much smaller file sizes while maintaining good perceived quality.
Will I lose quality converting FLAC to MP3?
Yes, MP3 is a lossy format so some audio data is discarded. However, at 320 kbps most listeners cannot distinguish MP3 from the original FLAC in blind tests.
What bitrate should I choose for MP3?
320 kbps offers the best quality and is recommended for music listening. 192 kbps provides a good balance between quality and file size. 128 kbps is suitable for spoken content or when storage is limited.
How much smaller will the MP3 file be?
A typical FLAC file is 3-5 times larger than an equivalent 320 kbps MP3. For example, a 50 MB FLAC track will convert to roughly 10-15 MB as a 320 kbps MP3.
Are my audio files secure during conversion?
Yes! All conversion happens locally in your browser using FFmpeg WebAssembly. Your audio files are never uploaded to any server, ensuring complete privacy.
