Some of the commonly used file types for images are JPEG, PNG and GIF, each one of these file types boasts of a fair share of advantages so lets discuss the pros and cons of utilizing these file formats, the type of image format that should live up to the requirements of your web page and optimizing your icons for the internet. GIF: It is the abbreviation for Graphics Interchange Format; the format is one of the most commonly used file types. The popularity of this format can be attributed small size which makes it easy to upload them. Unlike JPEG, information is not lost in this format which means you can store the image in a smaller size without messing the quality of the images. The format is also known to support transparency in pictures, it is the most appropriate formats for picture designing. Unlike the other formats, animation is also possible in GIF. If you wish to optimize a GIF file, it is necessary to limit the file size; it would be best that you pick a 32 color palette to get the smallest possible size. JPEG: This is the abbreviation for Joint Photographic Experts Group; the file format is commonly known as JPG and is usually incorporated for online graphics. One of the principle pros of using this type of file is that you could store the images in true color that affords you an impressive range of 16 million colors; making this image type suitable for storing photos and images that have detailed color range. One of the issues of utilizing JPG is the loss of details that you will have to deal with each time the image is stored; this means that the graphic is susceptible to blurriness and some data may be lost. Unlike the GIF format, transparency support is not offered in this format. If you have chosen an advanced image editing software for instance, the Adobe Photoshop, you will be able to choose the image quality and the size of the JPG file but it is vital to understand that a lower resolution equates to a smaller size, which is convenient to upload. PNG: Is short for Portable Network Graphics and is a very fresh file format. PNG is available in two forms; PNG-8 which offers 8 bit color format and the PNG-24 which has 24 color pictures. PNG-8 can compress graphics with great detail and without the usual loss of details seen in in GIF images; this gives better quality pictures and quick uploads. However, PNG-24 is not as efficient as JPG when you want to save photographs and other illustrations that merit the use of a vaster palette of colors. The format is loss-less; this means that the picture retains its quality and clarity. PNG-24 offers the transparency feature and you can utilize various levels of transparency in this file format. When you use this file format the graphics are better looking because you cant see jagged lines when inserted in relation to a background with contrasting colors like GIF files.
