Will I hear a difference after converting FLAC to MP3?

At 320 kbps the difference is inaudible to most listeners on most equipment. The gap only matters on high-end audiophile gear.

How much smaller will the MP3 be?

Typically 5-10x smaller than the original FLAC, since FLAC is lossless and MP3 discards inaudible audio data to shrink the file. A typical album shrinks from roughly 300 MB of FLAC to about 80 MB of MP3.

Can I convert several FLAC files to MP3 at once?

Yes. Add the whole album and click Convert — every track is converted separately, and a lossless release becomes a phone-ready set of MP3s in one pass. There is no limit on the number of tracks per batch.

Should I keep the FLAC files after converting?

If storage allows, yes. FLAC is your lossless master: you can always make a fresh MP3 (or any other format) from it later, but you can never rebuild the FLAC from an MP3. A common setup is FLAC on a home drive and MP3 copies on the phone and in the car.

Why won't my phone or car stereo play FLAC in the first place?

FLAC support is patchy outside dedicated players: many car head units, older phones, cheap MP3 players and Apple devices (which use ALAC instead) simply ignore FLAC files. Converting to MP3 sidesteps the whole compatibility question — every device of the last twenty years plays it.

What happens to hi-res FLAC, like 24-bit / 96 kHz?

It converts fine, but MP3 tops out at a 48 kHz sample rate, so the extra hi-res detail is discarded along the way. For everyday listening on normal gear that difference is inaudible — and the file drops from hundreds of megabytes to a normal MP3 size.

About FLAC and MP3

Key things to know before you convert FLAC to MP3:

FLAC

FLAC compresses audio to ~50-60% losslessly — every bit of the original survives. The format of music collections and audiophiles.

MP3

MP3 is the most compatible audio format in existence: every player of the last 25 years handles it. Less efficient than modern codecs, but compatibility usually wins.
