FLAC to MP3 FAQ
Will I hear a difference?
At 320 kbps most listeners cannot distinguish MP3 from FLAC in blind tests on typical equipment. Keep the FLAC files as your master copies anyway.
Is album art kept?
Text tags are kept. Embedded cover art is not transferred; add it afterwards with the Audio Tag Editor if your player needs it.
Why does the MP3 sound slightly different from a 24-bit FLAC?
MP3 is limited to frequencies the format and bitrate can carry, usually up to about 20 kHz, which covers the range of human hearing. High-resolution details beyond that are not represented.
Can I convert the other way?
MP3 to FLAC is possible but pointless: it creates a large file containing MP3 quality. Lossless files should always come from a lossless source.
How long does conversion take?
A few seconds per track on a typical computer; a full album takes a minute or two.
Lossless masters and portable copies
FLAC, the Free Lossless Audio Codec, compresses audio like a ZIP file compresses documents: the original samples come back exactly when decoded. It is the preferred format for CD rips and high-resolution downloads, typically using 50–70% of the space of an uncompressed WAV.
Lossless files are still large, around 30 MB for a typical song, and not every device plays them. Many car stereos, older players and some apps support only MP3 or AAC. Keeping a FLAC archive and generating MP3 copies for portable use gives the best of both: perfect masters at home and broad compatibility on the go.
Converting from FLAC is the ideal case for MP3 encoding because the encoder starts from a perfect source. At 320 kbps the result is about a quarter of the FLAC size and, for practical purposes, indistinguishable when listening on phones, in cars and with most headphones.
Tags make a music library usable. The converter copies the FLAC’s Vorbis comments, such as title, artist, album and track number, into the MP3’s ID3 tags, so players can display and sort the converted tracks correctly.
