Fit inside preserves the full image and keeps it within the dimensions you enter.

Enter at least one target dimension. With aspect ratio locked, ConvertThings can calculate the missing dimension automatically.

Flexible resizing

Fit inside a target box, fill dimensions with a centered crop, choose an exact draggable crop area, or unlock the aspect ratio for an exact width and height.

Safe by default

Prevent enlargement is enabled by default, while ConvertThings validates the real image type, dimensions, file size, and integrity before Imagick processes it.
