Resize options
- By percentage: shrinks every image by, say, 50% and keeps the proportions.
- By width / height: fixes one side and calculates the other.
- Fit in a box: the image shrinks to fit inside the width × height you give, keeping its proportions.
- Fill and crop: produces exactly the requested size, cropping the overflow from the centre (for example a 1080×1080 social media square).
Do not enlarge small images
With “Do not enlarge small images” on, images smaller than the target are left as they are. Enlarging does not add quality; it only bloats the file.
