Good questions. Simple answers.
Will it keep faint strokes?
Light cleanup preserves small details. Lower the threshold if faint strokes disappear; always compare with your original.
Can it remove any background?
It is designed for dark ink on light paper, not handwriting over photographs or complex patterned backgrounds.
