Icon sizes: 256x256, 48x48, 32x32, 24x24, 16x16 File formats: ICO, GIF, PNG, BMP Picking The Correct Image Format In Icon Creation.There are several file formats that should be utilized for storing web graphics and for a newbie web creator this can quickly lead to a big pain because you will need to understand how to utilize a specific format, given below is an explanation of the benefits and issues of some commonly used image formats.If you are interested in icon making or wish to create pictorial depictions for your web site, it is essential to know about the varied image file formats and their features so that you can utilize the right file format for graphics. Normally used file types for graphics are GIF, JPEG and PNG, every one these formats has its own traits so lets look at the benefits and drawbacks of incorporating these formats, the type of file that would meet the expectations your website and optimizing your icons for the web. GIF: The full form is Graphics Interchange Format; the format is one of the most commonly used file types. The reason for its popularity is its tiny image size which makes uploading a breeze. Also like JPEG, information is not lost in this image format which means you can store the graphic without using up a lot of space and messing the quality of the picture. Since GIF supports transparency in images, it is one of the most suitable formats for web graphic making. Unlike the other image formats, animation is also offered in GIF. If you want to optimize a GIF file, it is necessary to restrict the size of the file; it is recommended that you pick a 32 color palette to get the least possible size. JPEG: This stands for Joint Photographic Experts Group; the file format is generally called JPG and is often used on websites. One of the primary pros of using this type of format is that you will be able to save the graphics in true color that gives you an impressive range of 16 million colors; this renders the image type suitable for saving photos and pictures that include detailed color work. One of the problems of using JPG is the loss of details that is encountered each time the image is stored; this means that the graphic is susceptible to clarity issues and many information may be lost. Unlike the GIF format, support for transparency is not provided in this file format. If you have chosen a superior image editing program like the Adobe Photoshop, you can select the quality and the file size ; however, it is important to understand that a lower resolution will mean a small size, which is convenient to upload. PNG: Is an abbreviation for Portable Network Graphics and is a very fresh file type. This format is offered in two forms; PNG-8 which is the 8 bit color format and the PNG-24 which has 24 color graphics. PNG-8 can curtail the size graphics with fantastic detail and without the normal loss of details experienced in GIF files; this results in better quality pictures and quick uploads. But, PNG-24 is not as efficient as JPG when you need to store photographs and other graphics that merit the use of a vaster color palette. The image format is loss-less; this means that the picture holds on to its quality and clarity. PNG-24 supports transparency and you can use various levels of the transparency feature in this format. In this format the images are smoother because they do not have the tell tale jagged edges when inserted on a contrasting background like GIF files.
