Questions
Will my images be stretched?
No — width, height, percent and fit-in-box all keep the original proportions. Only “Exact size” can change the shape.
What does “Don't enlarge smaller images” do?
Images already smaller than the target are left at their size, because enlarging only makes them blurry.
