Everyone uses JPG, GIF and PNG files for photos and graphics. But if you're anything like me, you probably treat them indiscriminately. Well, apparently, there's a real difference. Having been recently enlightened by our web folks, I've decided to pass my newfound knowledge along. Here's a quick primer on the difference between these common file types.
JPGs are best for complex graphics and photographs. JPGs use a lossy compression technique. I.e., as the file is compressed, the image loses some of its data. Exactly how much data is lost depends on the amount of compression. The JPG format isn't ideal for text-heavy pictures or simple drawings that don't have the depth to survive the lossy compression. Such images tend to lose their sharpness and clarity when converted to JPG.
