In-depth guide

Understanding MP3 in practical workflows

MP3 became the default everyday audio format because it is easy to store, easy to share, and supported almost everywhere. It is especially useful when file size matters more than keeping every bit of the original source audio intact.

MP3 is a lossy audio format, which means some audio data is removed to reduce file size.
Higher bitrates usually preserve more detail, while lower bitrates create smaller files.
MP3 is often a better delivery format than an editing format.
Converting a low-quality MP3 into WAV or FLAC will not restore the detail that was already lost.
