How to Resize Images Without Losing Quality

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.
