Why convert M4A to OGG?
OGG may be better supported by your device or app. To keep quality, choose a bitrate equal to or higher than the original M4A.
OGG is best for games, Spotify-style streaming, open-source projects and web audio. Android, Chrome, Firefox, VLC, game engines (Unity, Godot). Limited on older Apple devices.
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.
