Understanding your result
A 2400 × 1200 image fitted inside 1200 × 1200 becomes 1200 × 600. The bounding box limits both edges while keeping proportions. Smaller originals keep their existing size. Compare portrait and landscape results separately if the destination expects a uniform shape.
What to do if you have a problem
If a photo remains smaller than your limits, it was not enlarged. If files are refused, check the count, file size and decoded pixel limits shown above the controls. Choose Width and Height, select the files and click Process images again when changing your target size.
What to know before using the result
Images are never enlarged. Animated images become a single still frame.
