FLAC vs. MP3: Which One is Better?

FLAC and MP3 are important audio formats in our daily lives and work, but they differ in their features, including sound quality, compatibility, file size, etc. If you want to figure out all the differences, the following information is right for you.


#1. Sound Quality

MP3, a data compression format for encoding digital audio, is one of the common audio formats. Known as the lossy format, it performs perfectly in file size, as most parts of the file are shaved off to ensure a small size. However, this audio format is far from the best sound quality because of that. In most cases, reverb, cymbals, and guitars are the most affected sound by the MP3 compression, and the audio files in MP3 format will sound distorted if there is too much compression is applied.

On the contrary, FLAC is a lossless format and always retains the audio quality it stores, so it is better than MP3 in the sound quality. It is more like a ZIP file whenever you test the sounding of the audio, and it will always be similar to the unzipped file. 

Tip: If you are the one who prefers high audio quality, FLAC may be your first choice.

#2. File Size 

Like we said before, the MP3 is a lossy format, and most parts of it are shaved off. So it performs better in the file size. 

However, compared to the MP3 format, FLAC files are bigger and need more storage capacities. This kind of audio file is up to six times larger than an MP3 file. That's because the FLAC files barely lose the content, which makes them quickly bulky, storage-wise.

Tip: If you often use a mobile device to listen to music, MP3 is suitable for you because of the small size.

#3. Compatibility

While speaking of playability or compatibility, which one is better?

Usually, we all know that the MP3 file can be played on almost all mobile devices and computers, and because all modern media players are able to open this file easily.

However, the FLAC audio file is not as widely used as MP3. It is compatible with most computers, but only several mobile phones can play it successfully. 

Tip: If you want to play your music anywhere, anytime, just try MP3!
