Why convert FLAC to MP3?
FLAC files are lossless audio — audiophile quality, but enormous (often 300MB+). Converting to MP3 at 192 or 320 kbps reduces the file to under 10MB while keeping quality indistinguishable to most ears.
What is FLAC?
FLAC (Free Lossless Audio Codec) is lossless audio with smaller files than WAV. Popular with audiophiles and music archivists.
What is MP3?
MP3 is the universal audio format — small file size, compatible with every device and app on the planet.

Yes. Because it runs in the browser, it works on any device — iPhone, Android, Mac, Windows, or Linux — as long as you have a modern browser like Chrome, Safari, Firefox, or Edge.
How long does FLAC to MP3 conversion take?
Conversion time depends on your file size and device. Most files convert in under 30 seconds. Longer videos or high-resolution images may take a minute or two. Nothing is being sent over the network, so your connection speed has no effect.
