FLAC keeps every bit of a recording, which is why an album takes a gigabyte and why many players and car stereos will not touch it. This page produces a compact MP3 from a FLAC on your device.
Choose the bitrate: 192 or 256 kbps keeps music close to transparent; 128 kbps is plenty for speech. Trim, or split a long file into equal parts.
Nothing is uploaded; a whole album converts locally.

Frequently asked questions
Are my files uploaded to a server?
No. This conversion runs entirely inside your browser using your own device’s processing power. The file never leaves your computer or phone, which is why it also works when your connection drops.
How much smaller will the MP3 be?
Roughly five to ten times smaller than the FLAC, depending on the bitrate you choose.
Is the loss audible?
At 256 kbps almost nobody can tell in a blind test. Keep the FLAC as your master and use the MP3 for devices.
