NCM to MP3 FAQ
Will converting NCM to MP3 lose quality?
Both NCM and MP3 are lossy formats. Re-compression may further reduce quality — choose a higher bitrate to minimize additional loss.

Converting to a lossless format (WAV) usually increases size, while converting to a lossy format (MP3, AAC) usually decreases it, depending on the chosen bitrate and sample rate.
