FLAC (.flac) · Max 20 MB

FLAC is what you rip CDs to and what hi-res download stores sell, and it is superb — bit-perfect, lossless, and about half the size of the raw WAV. It is also awkward: an album runs 250-400 MB, Apple's Music app refuses to import it at all, plenty of car stereos ignore it, and many players and phones handle it inconsistently. Converting to MP3 solves the practical problem while leaving your masters untouched.

The size change is the point. A 35 MB FLAC track becomes roughly 7-9 MB as a 320 kbps MP3 — a lossless album that ate 350 MB comes down to about 80 MB. That is the difference between fitting a handful of albums on a device and fitting your collection.

Because FLAC is lossless, this is the ideal starting point for an MP3 encode: the encoder receives the complete original signal, with no artifacts inherited from a previous lossy step. An MP3 made from FLAC at 320 kbps is as good as an MP3 of that music can be — meaningfully better than one re-encoded from another lossy file.

Keep the FLACs. That is the whole discipline here: FLAC is the archival master, MP3 is the copy that travels. MP3 is lossy and what the encoder discards cannot be recovered, so if you later want a different bitrate, a different format, or a proper lossless copy for a new device, you re-encode from the FLAC — never from the MP3.

Free here means free: no account, no watermark tone, no queue, and no upload. The conversion runs in your browser with WebAssembly, so your library stays on your own disk. Free covers files up to 20 MB with a 10-second preview; Pro ($9/mo) handles full-length tracks up to 500 MB, which is what you want for whole albums.

Frequently Asked Questions

How much smaller is MP3 than FLAC?

Roughly a quarter of the size at 320 kbps. A 35 MB FLAC track becomes about 7-9 MB; a 350 MB lossless album comes down to around 80 MB.

Will I hear the difference between FLAC and a 320 kbps MP3?

In normal listening — phone, car, earbuds — almost certainly not. On a good system with careful listening, some people can detect differences on some material. That is exactly why you keep the FLAC as the master and use MP3 as the portable copy.

What bitrate should I convert FLAC to?

320 kbps if quality matters and space is not tight; 256 kbps is a very reasonable compromise; 192 kbps is fine for casual listening in noisy environments. Encoding from lossless FLAC means you get the best possible MP3 at whichever bitrate you pick.

Should I delete the FLAC files afterwards?

No. MP3 is lossy — the discarded detail is gone for good. Keep the FLAC as your archival master so you can re-encode to any future format or bitrate; the MP3s are disposable copies.
