Why use aspect ratio lock?
Changing width and height independently can distort an image, stretching it horizontally or vertically. Aspect ratio lock ensures the image keeps its original proportions when you change one dimension: the other updates automatically to match.
Which format should I choose?
Choose JPG for photographs. It's the smallest and universally supported. Choose PNG if you need transparency or pixel-perfect sharpness (logos, screenshots). Choose WebP for the web. It delivers the smallest file size at equivalent quality and is supported by all modern browsers.
