Frequently asked questions

MP3 or FLAC: Which is better?

MP3 vs. FLAC: which format is better? It depends largely on other audio settings and the quality at which they have been mixed and produced. However, FLAC files are generally better due to the fact that they have lossless compression, which means that they contain more detail and data than the average MP3 file.

On the other hand, if you are looking for small files and the most possible compatibility, then MP3 files could be a good option, it is all about choosing what is suitable for each scenario.

Does converting MP3 to FLAC improve quality?

Not necessarily, if you are starting with a file that has already lost details by going through lossy compression, then the conversion to FLAC will not be able to restore that data. FLAC files should be sourced from the highest possible original audio quality to keep loads of the data there and preserve quality.

Is MP3-to-FLAC a lossless conversion?

The process of converting MP3 to FLAC won’t lose any data, but it also won’t restore any of the data that may have been lost in creating the MP3. Many people are looking for information on how to turn FLAC into MP3 files, too. Though this is lossy, it does result in much smaller file types.
