Image Compression: Importance of Gif, Jpeg and Lossy Method in Web Designing
Graphics and images form an integral part of website designing. Graphics have an engrossing appeal and thats why they attract more and more visitors. But, due to expensive bandwidth and time-consuming downloads; it has become essential to compress data and images. Compressing data means the ability to crunch an image or text into a smaller size. Compressing images or graphics makes use of special algorithms to measure pixels. The pixels are used as single items in a compression method.
A compressed image consumes less storage space. The bandwidth required is also less compared to uncompressed data. There are two fundamental methods for compressing data:
The Lossy compression technique is preferred by most companies specializing in custom web site design India. It is mainly used for crunching graphics, audio and video signals. Images compressed using lossy technique may have lower resolution and sharpness than the original. In case of audio and video, the lossy technique compresses to 5 percent of original size.
Almost every custom web site design company in India use different image formats. These image formats consume less space and take less time while downloading. One of the most popular formats used is the Graphic Interchange Format or GIF. GIF formats support 8-bit color palettes and keep files relatively small. Most Ecommerce website design companies in India use GIF format in the designing because many image files can be compressed into a single GIF file, especially if an animation is created.
Apart from GIF formats, JPEG formats are widely used in websites. JPEG format can compress an image file a 100 times than the original size. A custom web site design company in India easily controls the compression elements of JPEG files. The complicated drawings and images do not lose their overall quality and the download speed is quite faster than other file formats.
