Resize Options Explained

Percentage Scaling

Simple & Proportional: Scale images by percentage (1-500%). Perfect for consistent sizing across multiple images.

Example: 50% makes a 1000x800px image become 500x400px.

Pixel Dimensions

Precise Control: Set exact width and height in pixels. Choose to maintain aspect ratio or set exact dimensions with cropping.

With aspect ratio on, setting width auto-calculates height.

Maintain Aspect Ratio

Preserve Proportions: When enabled, images resize proportionally without distortion.

Exact Fit: When disabled, images are center-cropped to fit exact dimensions.
