The Preview application comes standard on Macintosh OS X installations. The program is primarily an image-viewer (.pdf, images, etc.), but can be used for many other purposes.

Cropping

1. Open the image (.jpg, .jpeg, .png, .gif, .tiff, etc.) in Preview.
2. Click and drag over the image until a box appears. Drag the handles of the box to the desired crop points.
3. In the menu at the top, go to Tools, then click "Crop". Users may also click the crop button in the toolbar at the top.
4. Save the cropped image. If you do not save, the image will revert to its previous dimensions.

Scaling/Resizing

1. Open the image (.jpg, .jpeg, .png, .gif, .tiff, etc.) in Preview.
2. In the scale box (in the toolbar at the top), type in the desired size (i.e. 50%), then hit enter.
3. To save the resized image, type SHIFT+CMD+4, click and hold the mouse while tracing the outline of the image.
4. The new image will appear on the user's desktop in the format, "Picture #".
