About ConvertFLAC
A FLAC to MP3 converter that does the work on your own device.
What it does
ConvertFLAC turns FLAC audio files into MP3. You drag a file in, you get an MP3 out. That's the whole product. It is built for people who just want a quick, private conversion without installing software or creating an account.
How it works
Everything runs in your browser:
- Your browser decodes the FLAC file using its built-in Web Audio engine.
- The audio is encoded to MP3 with lamejs, a JavaScript MP3 encoder.
- The finished MP3 is handed back to you as a download.
No part of your audio is uploaded to a server. There is no backend that touches your files.
Why browser-only
- Private. Files never leave your computer.
- No account. Nothing to sign up for, nothing to remember.
- No limits. No file size cap, no daily quota.
- No cost. Free to use.
What it is not
This is a focused tool. It converts FLAC to MP3. It does not edit audio, batch-merge tracks, or convert other formats. If you need those, this is not the right tool — and that's fine.
