Some of the commonly used file types for graphics are JPEG, PNG and GIF, all of these formats has its own traits so lets talk about the pros and cons of using these formats, the type of image format that should meet the expectations your website and optimizing your icons for the web usage. GIF: The full form is Graphics Interchange Format; the image format is one of the most commonly used file types. The reason for its popularity is its tiny image size which makes it easy to upload them. Also like JPEG, details are not lost in this format which means you can save the image without using up a lot of space and deteriorating the quality of the images. The format is also known to support transparency in images, it is by far the most commonly used file formats for web graphic making. Unlike the other image formats, animation is also possible in GIF. If you would like to optimize a GIF file, it is vital to restrict the size of the file; it would be best that you choose a 32 color palette to get the smallest possible size. JPEG: This stands for Joint Photographic Experts Group; the file format is generally known as JPG and is often incorporated on websites. One of the primary benefits of utilizing this type of format is that you will be able to store the pictures in true color that affords you an impressive range of 16 million colors; making this file format ideal for storing photos and graphics that have detailed color work. One of the problems of utilizing JPG is the data loss that is encountered each time the file is saved; this points to the fact that the graphic is prone to compromised clarity and some details may be lost. Unlike other file formats such as GIF, transparency support is not offered in this file type. If you have chosen an advanced image editing program like the Adobe Photoshop, you will have the liberty to choose the quality and the size of the JPG file ; however, it is vital to realize that a lower resolution will mean a small size, which is easy to upload. PNG: Is stands for Portable Network Graphics and is a relatively new file format. PNG is available in two versions types; PNG-8 which offers 8 bit color format and the PNG-24 which uses 24 color graphics. PNG-8 can compress images with wonderful detail and without the customary loss of data observed in the GIf format; this results in better quality pictures and quick uploads. But, PNG-24 is not as effective as JPG when you want to store pictures and other images that merit the use of a vaster color range. The format is sans loss; this means that the photograph holds on to its clarity and quality. PNG-24 offers transparency support and you can include different levels of the transparency feature in this format. With this type of file the images are better looking because they do not have the tell tale jagged edges when placed in relation to a contrasting color backgrounds like GIF files.
