By percentage: scale the image proportionally, e.g. 50% halves both width and height;Fixed dimensions: specify target width and height; enable keep aspect ratio to avoid distortion;Max side length: limit the longest side of the image to a given value; the short side scales proportionally.
Keep Aspect Ratio
In fixed dimension mode, with keep aspect ratio enabled, entering the target width or height automatically calculates the other side based on the original ratio, avoiding stretching or distortion.
