4. Change the Print Size of an Image
You can change the printed size of an image to determine how it appears on paper. The printed size of an image depends on the number of pixels in the image and the resolution, which measures the pixel density on the printed page.

8. Change the Resolution of an Image
You can change the print resolution of an image to increase or decrease the print quality. The resolution, combined with the number of pixels in the image, determines the size of a printed image. The greater the resolution, the better the image looks on the printed page — up to a limit, which varies with the type of printer and paper quality.

13. Crop an Image
You can use the Crop tool to change the size of an image by removing unneeded space on the top, bottom, and sides.

18. Trim an Image
You can use the Trim command to automatically remove any blank space surrounding your image. This can be useful for scanned photos or when you want to minimize the file size of an image. Options let you trim space from all four sides or just some of them.

21. Change the Canvas Size of an Image
You can alter the canvas size of an image in order to change its rectangular shape or to add blank space around its borders. The canvas is the area on which an image sits. Changing the canvas size is one way to crop an image.
