Lossy formats have a bitrate related to them (or a "high quality" setting), which lets you determine what level of commerce-off area vs high quality is appropriate to you.
Lossless formats, FLAC for example, don't sacrifice any high quality within the transition. They make a perfect digital copy of each bit from the original supply. The bitrate is not a measure of quality anymore, it's simply a measure of how much compression the software program was able to obtain, without sacrificing any knowledge. These files are typically much larger than lossy codecs, and the standard challenge is negligible.
FLAC stands for Free Lossless Audio Codec, an audio format much like MP3, however lossless, meaning that audio is compressed in FLAC without any loss in high quality.

I think soundKonverter on KDE might do this for you. Some customers have reported that this system m4a to flac converter online stops letting you change information after 14 days. I haven't experienced this however hold it in thoughts, and use a special tool from this list when you run into that.
