No, converting MP3 to DFF does not cause additional quality loss — DFF uses lossless compression. However, any artifacts already present in the original MP3 file will persist in the DFF output.
DFF files are typically 2-5x larger than equivalent MP3 files because DFF preserves all pixel data. This is expected and necessary for lossless quality.
