When a photo and a print have different proportions, something must give. You can crop part of the picture, leave blank space, or distort the picture. Our tools offer the first two choices. They never stretch an image to force it into a different shape.
Compare shapes, not just sizes
Aspect ratio is width divided by height. A 6 × 4 inch photograph and a 12 × 8 inch photograph both have a 3:2 ratio. They can use the same crop. An 8 × 10 inch portrait has a 4:5 ratio, so it needs a different crop from a 4 × 6 inch portrait even though both are rectangular.
A worked example
Take a landscape image measuring 3,000 × 2,000 pixels and prepare a 10 × 8 inch print. Crop to fill retains 2,500 × 2,000 pixels. A centered crop removes 250 pixels from each side: one-sixth of the original image area is gone. Moving the crop left or right changes which pixels are removed, but does not change the retained area.
Fit whole image instead makes the photograph 10 × 6.67 inches inside the 10 × 8 area. That leaves about 0.67 inches of blank space above and below a centered image. This is often the better choice if the edges contain a signature or someone's face.
Use the crop preview deliberately
- Choose an image from your device. Swetter processes it locally.
- Set the intended print width and height. These define the crop shape, not the number of output pixels.
- Move the horizontal and vertical position sliders to protect the subject.
- Download the cropped PNG and check it again in your print software.
The download uses available source pixels and does not enlarge the picture. Its physical printed size must still be set in your printing application. Changing the ratio can reduce the number of pixels available for the final print.
Leave breathing room
A crop preview is a geometric guide, not a model of your printer or frame. Some frames cover the picture's outer edge. Borderless printing may enlarge the image slightly. Keep important details inside the intended edge and check the requirements of the frame or print provider. When exact positioning matters, make a proof on inexpensive paper first.
