Why convert OGG to M4A?
M4A may be better supported by your device or app. To keep quality, choose a bitrate equal to or higher than the original OGG.
M4A is best for iPhone, iTunes/Apple Music, YouTube uploads and efficient music storage. Excellent on Apple devices, Android, Windows, browsers and most modern 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.
