Among the most popular file types for graphics are GIF, JPEG and PNG, each one of these file types has its own traits so lets discuss the advantages and disadvantages of using these file formats, the type of image format that would live up to the requirements of your website and optimizing your icons for the internet. GIF: It is short for Graphics Interchange Format; this is by far the most popular file type. The popularity of this format can be attributed image size that is very small which makes uploading a breeze. Unlike JPEG, information is not lost in this image format this means you can store the image in a smaller size without messing the image quality. The format is also known to support transparency in graphics, it is by far the most commonly used image formats for web graphic creation. Unlike the other formats, animation is also possible in GIF. If you would like to consider GIF image optimization, it is necessary to keep the size of the image small; it is advisable that you select a 32 color palette to get the smallest possible size. JPEG: This is short for Joint Photographic Experts Group; the file format is generally called JPG and is often seen on websites. One of the principle advantages of incorporating this type of format is that you can store the images in true color that gives you as many as 16 million colors; making this image type ideal for saving photographs and images that have vast color range. One of the cons of using JPG is the data loss that is encountered every time the picture is saved; this points to the fact that the picture is susceptible to compromised clarity and a lot of information may be lost. Unlike the GIF format, transparency is not possible in this format. If you are using an innovative image editing software for instance, the Adobe Photoshop, you will be able to choose the quality and the size of the JPG file but it is important to understand that a lower resolution will mean a small size, which is easy to upload. PNG: Is an abbreviation for Portable Network Graphics and is a relatively fresh file format. This format is offered in two forms; PNG-8 which has a 8 bit color format and the PNG-24 which offers 24 color graphics. PNG-8 can compress images with fantastic detail and without the customary loss of information experienced in in GIF images; this results in better quality pictures and quick uploads. But, PNG-24 is not as efficient as JPG when you want to save pictures and other images that require a more detailed color range. The file type is sans loss; this means that the picture retains its crispness and quality. PNG-24 supports transparency and you can utilize different levels of of the feature in this format. When you use this file format the graphics are better looking because they do not have the jagged edges when placed on a background with contrasting colors like GIF files.
