When preparing images for the web, you can
use the save for web dialogue box, and it gives you the most control when exporting images. To smooth out the appearance of curves with anti-aliasing, you can use the command and control plus button this allows the user to zoom into the picture.
The objective is to scale down the image as much as possible while sustaining high quality of the picture. In order to save for web, you must follow the simple steps of selecting file, export, save for web and in the dialogue box. To make sure the user can see the whole image select fit in view.
To compare the original image and exported image, the Two-Up- view is available. The file format JPEG does not support transparency. The best file format for an image is a PNG image which allows you to reduce the number of colours in the image.
