Some of the commonly used file types for images are GIF, JPEG and PNG, each one of these file formats has its own traits so lets look at the benefits and drawbacks of using these formats, the type of file that would meet the expectations your website and optimizing your icons for the internet. GIF: It is the abbreviation for Graphics Interchange Format; the image format is by far the most popular file type. The reason for its popularity is its small size which makes uploading a breeze. Unlike JPEG, information is not lost in this format ; this equates to the fact that you could store the image in a smaller size without deteriorating the quality of the images. The format is also known to support transparency in pictures, it is one of the most commonly used image formats for icon creation. Unlike the other image formats, scope for animation is also possible in GIF. If you want to go for GIF file optimization, it is vital to restrict the size of the file; it is advisable that you select a 32 color palette to get the least possible size. JPEG: This is the abbreviation for Joint Photographic Experts Group; the file format is generally known as JPG and is frequently used in web designing. One of the main pros of using this type of image is that you will be able to save the images in true color that affords you as many as 16 million colors; this renders the image type suitable for use with photos and graphics that boast of vast color work. One of the cons of using JPG is the information loss that is encountered every time the image is saved; this equates to the fact that the image is marred by compromised clarity and a lot of data may be lost. Unlike the GIF format, transparency is not possible in this file type. If you are using an innovative image editor for instance, the Adobe Photoshop, you will have the liberty to pick the quality and the file size ; however, it is imperative 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 new file format. PNG format is provided in two versions types; PNG-8 which has a 8 bit color format and the PNG-24 which has 24 color images. PNG-8 can compress graphics with great detail and without the customary loss of details observed in in GIF images; this gives high picture quality and fast uploads. However, PNG-24 is not as effective as JPG when you have to save photos and other images that need a vaster color range. The file type is sans loss; this means that the picture maintains its crispness and quality. PNG-24 offers the transparency feature and you can include varying degrees of transparency in this image type. When you use this file format the graphics are better looking because they do not have the jagged edges when placed against a background with contrasting colors like GIF files.
