Why convert AMR to AAC?
AAC may be better supported by your device or app. To keep quality, choose a bitrate equal to or higher than the original AMR.
AAC is best for streaming, broadcast and devices that need a raw AAC stream. Most phones, browsers, smart TVs and media players.
Will I lose quality?
Converting between two lossy formats re-encodes the audio, which can add a small amount of loss. Use a bitrate at least as high as the original (192 kbps or more) to keep it transparent.
