Resize by Percentage
Scale any image up or down by a percentage of its original size. Enter 50% to halve dimensions, 200% to double them, or any value from 1% to 500%. Unlike pixel-based resizing, percentage resizing always maintains the original aspect ratio perfectly, making it ideal for quick scale adjustments without the need to calculate exact pixel dimensions.
