Icon sizes: 256x256, 48x48, 32x32, 24x24, 16x16, 512x512 File formats: ICO, GIF, PNG, BMP Why Do You Need to Use PNG Image Format in Your Website Creation?The pros of incorporating PNG file format in website designing over various other formats such as GIF and JPEG; the file format works well if you need to make really amazing and wonderful icons that will wow your consumersThe PNG file type was introduced a few years back; it was put forth for consumers in the mid 90's to meet the deficiencies of the traditional GIF file type. However, it did not catch on because the the browsers of the time were not designed to support the progressive offerings of PNG so web designers and makers had to use it stingily. One of the major hurdles that marred the features of PNG was with Microsoft's Internet Explorer which was by far the most famous browsers of the time; IE had little or no provision for PNG support consequently the format could only be made use of in limited capacity. Then, things changed after the availability of IE7; this fresh browser from Microsoft has aided in increasing the popularity of PNGs. So here is a look at three reasons why PNG is by far the best image formats in the market today: You will be able to create images that can be superimposed due to their transparency or a property known as alpha transparency: When you analyze the features of GIF and PNG, it will become apparent that A definitive difference in the two formats is that you will only be able to save a specific color as transparent in GIF this simply means that the color can be used whether opaque or transparent with no other color in between with the use of PNG, you get a serious advantage; because the format can be used to produce semi transparency. This feature gives you the ability to save a PNG file with a soft drop shadow and then fuse it with a background that suits your taste. You can also use the image as a gradient background or water mark. The file type gives you the option to use the gradual fading of colors from entirely opaque to see through, and hence you will be able to view the webpage that lies in the background They look fantastic: Not only do you get surprising flexibility when using PNG images but also; there are a myriad of other benefits to incorporating this format. For example, when you use a JPEG image, you lose some of the details from the original file every time the file is saved, so after a while, you will be able to view a noticeable downgrade in the quality of the pictures. Even if, this issue has been resolved in GIF and you will be able to store the files without compromising any information, GIF only allows for a limited 256 color palette, which makes it quite ineffective if you want to store a snap shot. On the other hand, if PNG is incorporated, you could get the best benefits of both these formats; you will have access to a complete color display similar to JPEG images and it also provides managed color palette as seen in GIF files. Another advantage is that the storage of the file is sans loss so the photograph stays as it is regardless of how many time you save it. Self Optimization is possible in PNG: A major concern that web designers have to tackle frequently is the fact that the contrast and the brightness of the monitor has to be changed to see the pictures appropriately; this problem occurs due to various Gamma setting used in monitors from different vendors. Gamma is a technology that helps to scatter the luminance across the display surface. However, different operating systems use varying Gamma settings. Therefore, a picture that is color corrected to suit Windows may appear abnormal in Mac. Again, in this scenario the versatile PNG picture format can prove useful, in PNG, you can save the files with an inherent Gamma correction feature so regardless of the operating system; the Gamma settings will be realigned to display a file with the perfect brightness and contrast.
