Turn lossless FLAC albums into MP3 files for your phone, car or any player, right in your browser with the tags kept - want one long track instead? Merge FLAC joins files first.
Need to trim a track afterwards? Use the MP3 Cutter.
FLAC is lossless.
It shrinks audio like a ZIP file, and every bit of the original comes back when you play it.
MP3 is lossy: it removes sounds people barely hear, so a song gets 3 to 5 times smaller. At 320 kbps most listeners cannot tell them apart on phones, car stereos or Bluetooth headphones.

Combining tracks into one file? Merge FLAC keeps them lossless.
Got a WAV master instead? WAV to MP3 works the same way.
Title, artist, album, track number, year and genre are copied from the FLAC Vorbis comments into the MP3 ID3 tag, so your player sorts the album correctly.
Embedded cover art is not copied yet - most music apps fetch covers on their own. MP3 encoding by LAME (LGPL), on your own device.
Drop your FLAC files into the box, keep 320 kbps or pick a preset, and press Convert to MP3.
A whole album downloads as one ZIP.
320 kbps keeps the most detail and is selected here. 256 kbps is near-transparent too, and 192 kbps is a good choice when phone space matters.
At 320 kbps almost nobody can tell them apart on phones, car stereos or Bluetooth headphones. On a very good hi-fi, careful listeners sometimes can - that is why you keep the FLAC as your master copy.
Yes. Title, artist, album, track number, year and genre are copied from the FLAC into the MP3 ID3 tag. Cover art is not copied yet.
No. Your browser decodes the FLAC and the LAME encoder writes the MP3 on your device. Nothing is sent to us.
Yes. 16 and 24-bit FLAC at any common rate work. MP3 stops at 48 kHz, so hi-res files are resampled to 44.1 kHz - the page tells you when that happens.
Very old browsers cannot decode FLAC. Try a current Chrome, Edge, Firefox or Safari - they all read FLAC natively.
Up to 50 FLAC files per batch, up to 200 MB each. More than two MP3s come as one ZIP, and recent conversions stay in this browser.
