About the conversion
FLAC compresses audio without losing anything: the file is about half the size of the original WAV, yet every bit of the original is preserved. The price is storage — an album in FLAC runs 300 to 500 MB, while the same music as MP3 fits into 50 to 80 MB. On a home system that is fine; on a phone or a USB stick for the car, space runs out fast.
So the usual arrangement is this: keep the collection in FLAC and make an MP3 copy for the phone, the player or the car stereo. That also solves compatibility, since many car stereos and budget players cannot read FLAC at all, while every one of them handles MP3.
Here you are converting from a lossless source, which means the original data is complete and the result will be as good as the bitrate you choose allows. For music it is worth using 256 or 320 kbps — on ordinary headphones and speakers such an MP3 is practically indistinguishable from the original, and your FLAC files stay untouched.
Frequently asked questions
Why convert FLAC to MP3?
For space and compatibility. A FLAC album takes five to six times more room than the same album as MP3, and many car stereos, players and speakers cannot read FLAC. An MP3 copy solves both problems while the original stays in your collection.
Which bitrate should I use for music?
320 kbps for maximum quality, or 256 kbps as a sensible balance between sound and size. Since the source is lossless, at these bitrates the difference is not detectable on normal equipment.
How much smaller will it be?
Roughly five to six times. A 400 MB FLAC album becomes 60 to 80 MB as MP3 at 320 kbps, and smaller still at a lower bitrate.
Will I lose sound quality?
Formally yes: MP3 is lossy and FLAC is not. In practice, at 256 to 320 kbps the difference is inaudible on most headphones and speakers — and your original FLAC files remain exactly where they were.
Is anything uploaded?
No. The conversion runs in your browser on your own device; your music is never sent to any server.
