Not only the code and text it is the graphic which comprise the weight of the web site page. In fact graphics in many cases form the bulk of the web page. Graphics are a must on the web page as they convey lot to information – specific and non specific.
Weighty site means slow download. Minimize the image file size witout loosing color consistency, image quality and resolution.This is right for website development as it also helps in conservation of bandwidth.
Use the right format in web design process to get better and perfect results. Professional web development is all about understanding and using the most suitable formats.
GIF – Graphic Interchange Format -It is 256 color lossless compression format – every pixel of the original image is retained in optimized iamge. It is compatible with all web browsers. GIF is best for depicting logos, drawings and simple graphics. GIf is useful in animated web designs as well it result in light weight animations.
JPEG – Joint Photographic Experts Group – It can include sixteen million plus colors. JPEG is highly useful for detailed and realistic images as that in the case of a photograph. JPEG accord true colors and not from the limited palette as in the case of GIF.JPEG results much smaller file size but highly compressed images are pixilated. This is because of lossy algorithms and no animation or transparency is possible.
PNG – Portable Network Graphic – Most popular browsers handle PNGs well both 8 bit and 24 bit. It optimizes images with lossless compression like GIF. Full color PNGs have a place in web design technology as they support transparency and limited pallete yields better results than GIF.
