What is aspect ratio lock?
Aspect ratio lock ensures that when you resize image files, the proportions stay the same. If you resize image width to 800px, the height automatically adjusts to match the original ratio — so your image will not look stretched or squished.
Does resizing reduce image quality?
When you resize image files to smaller dimensions, quality is preserved well. When you resize image files to larger dimensions than the original, quality decreases because pixels must be stretched. For best results, always resize image files to equal or smaller dimensions than the original.
