Resizing Images Resizing images (pictures and photographs), or reducing the file size of saved image files, is accomplished by using one or more of the following techniques:
Backgrounds Removing unnecessary backgrounds significantly reduces the size of image files. The tutorials below walk you step-by-step through this cut & paste operation. File Format Saving your images (pictures and photographs) in the correct file format is important, and the issues to consider when selecting a format are (a) compression, and (b) compatibility. Although less superior to PNG (Portable Network Graphics), JPEG (Joint Photographic Experts Group) is supported by all web browsers, as well as by the majority of image-viewing software programs. For compatibility and general viewing purposes, then, all images should be saved in JPEG format. Dimensions A small picture often tells the same story as a large picture. Consider reducing the dimensions (physical size) of your image before sending this to others. Resolution/Quality Reducing the resolution and quality of an image accelerates transfer speeds. Try this option before saving your final image. Gray Scale Is it really necessary to send the image in full colour? Converting an image to gray scale (black and white) reduces the file size by approximately 50%. TUTORIALS The tutorials below walk you step-by-step through each of the above file-reducing operations.

Caution Freeware and shareware applications often contain spyware, an intrusive little utility that monitors your travels on the web and then relays this information back to the developers.
