It permanently discards audio information that most listeners are unlikely to notice, which makes files small.<\/li>\n\n\n\n<li><strong>FLAC<\/strong> is <em>lossless<\/em>. It compresses the audio without discarding anything, so decoding gives back exactly what went in, like a zip file for sound.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For the general idea, see <a href=\"\/blog\/lossy-vs-lossless-compression\">lossy vs lossless compression<\/a>, and for the format itself, <a href=\"\/blog\/what-is-flac-audio\">what FLAC is<\/a>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">File Size<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Format<\/th><th>Typical size for a 4-minute song<\/th><th>Notes<\/th><\/tr><\/thead><tbody><tr><td>MP3, 128 kbps<\/td><td>About 4 MB<\/td><td>Smaller, noticeably compressed<\/td><\/tr><tr><td>MP3, 320 kbps<\/td><td>About 9\u201310 MB<\/td><td>The high-quality MP3 setting<\/td><\/tr><tr><td>FLAC<\/td><td>Often 20\u201335 MB<\/td><td>Varies with the music<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">FLAC files are commonly several times larger than a good MP3. A library of 5,000 songs might be around 50 GB in MP3 but 150 GB or more in FLAC, so the numbers add up. <a href=\"\/blog\/what-is-bitrate-video-audio-explained\">What bitrate means<\/a> explains why MP3 sizes scale the way they do.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Sound Quality: What&#8217;s Actually Audible<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A high-bitrate MP3 (256\u2013320 kbps) is very hard for most people to tell from lossless on typical headphones and in everyday settings. Blind tests regularly show that many listeners can&#8217;t reliably pick the difference.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Where FLAC can pay off:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Good equipment<\/strong> in a quiet room, where subtle detail becomes easier to hear.<\/li>\n\n\n\n<li><strong>Low-bitrate MP3s<\/strong> (128 kbps and below), where artifacts such as a &#8220;swishy&#8221; high end can show.<\/li>\n\n\n\n<li><strong>Complex music<\/strong> such as classical or dense acoustic recordings.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Where it usually won&#8217;t: car stereos, earbuds on a commute, and background listening.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">The Biggest Myth: Converting MP3 to FLAC<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Converting an MP3 into a FLAC does not restore lost quality. The detail is already gone; you just get a bigger file holding the same MP3-quality sound. FLAC is only worth having if the source was lossless to begin with, such as a CD rip or a purchase from a lossless store.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reverse is fine and common: keep a FLAC master, then make MP3 copies for your phone.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Compatibility<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>MP3<\/strong> plays on everything made in the last twenty years.<\/li>\n\n\n\n<li><strong>FLAC<\/strong> is supported by most modern phones, desktop players, and many car systems and streamers, but some older devices and a few apps don&#8217;t support it.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If a device won&#8217;t play FLAC, convert a copy to MP3 or AAC.

Whether you can hear it depends on your equipment and the MP3&#8217;s bitrate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can people really hear the difference?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, with good gear and careful listening. Many can&#8217;t tell a 320 kbps MP3 from lossless in blind tests.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does converting MP3 to FLAC improve quality?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. It only makes the file bigger.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why are FLAC files so large?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">They keep all the audio information, compressing it without discarding anything.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Will FLAC play on my phone?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most current phones can play it, either natively or with a free app. Check your music app.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is FLAC the same as WAV?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Both are lossless, but FLAC is compressed and smaller, while WAV is uncompressed.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>FLAC and MP3 both store music, but they make opposite trade-offs: FLAC keeps everything and takes more space, MP3 throws some detail away to stay small.
