When it comes in handy
For example, it helps when you need to shrink a large photo to fit a 1024px width limit on a board.
It is also handy for reducing a 4000px original down to an 800px thumbnail.
Keep the aspect ratio
Resize by pixel dimensions while keeping the aspect ratio, so changing one side adjusts the other. The original is left as-is and a new image is created.
The ratio lock keeps it simple
For example, set the width to 800px and, with the ratio lock on, the height adjusts automatically to keep the original proportions.
