Keep width and height linked
When the ratio lock is active, changing one dimension calculates the other automatically. A 3:2 image remains 3:2 at every size, so the content is scaled rather than stretched.
Crop when the destination has another shape
If a layout requires a square but the source is landscape, proportional resizing alone cannot fill the frame. Crop to 1:1 first, then resize to the required pixel dimensions.
Prefer downscaling
Reducing dimensions combines existing detail and normally looks clean. Enlarging asks the browser to invent intermediate pixels, which can look soft. Use the highest-quality source and avoid multiple resize-and-save cycles.
