If you store digital music as FLAC files, but your portable player can't play them, you'll need a tool like FLAC to MP3 Converter. FLAC stands for Lossless Audio Codec. It is a free and open source standard for compressing audio files. It's popular because it's lossless: storing your music as FLAC files preserves their quality better than more "lossy" standards, including MP3. While many media players handle FLAC files, many portable devices cannot. It is very simple to use.

The user interface of FLAC to MP3 Converter is small and simple, with no controls, options or settings other than those that are immediately accessible. We can drag and drop files into the main window, or click Add and browse to our FLAC files, or click Delete to remove them from the list. We tried both methods. The next step after adding the files is to select the output folder by changing the selection from Same (save the converted files to the same folder as the source files) to Other and browse to the new destination folder. Then just press Convert to MP3 to process our batch. That's all there is to the program interface and functionality.
