FAQ
What is an aspect ratio?
An aspect ratio is the proportional relationship between an image or display’s width and its height (e.g. 16:9 for widescreen video, 1:1 for square).
How do you resize images without stretching?
By scaling one dimension and calculating the other using the simplified aspect ratio formula (New Height = (New Width × Original Height) / Original Width).
