Some of the commonly used file formats for graphics are PNG, GIF and JPEG, all of these formats has its own traits so lets discuss the advantages and disadvantages of using these file formats, the type of image format that would suit your website and optimizing your images for the web usage. GIF: It is short for Graphics Interchange Format; this is by far the most popular file type. The image format is well accepted because of its image size that is very small which makes uploading less time consuming. Also like JPEG, information is not lost in this file type which means you could store the graphic at just a few bytes and without deteriorating the image quality. The format is also known to support transparency in pictures, it is by far the most commonly used formats for picture creation. Unlike the other image formats, animation is also possible in GIF. If you want to go for GIF file optimization, it is important to limit the file size; it is advisable that you select a 32 color palette to get the least possible size. JPEG: This stands for Joint Photographic Experts Group; the file type is generally known as JPG and is usually used in web designing. One of the main pros of incorporating this type of image is that you could save the images in true color that offers you as many as 16 million colors; this makes the image type appropriate for use with photos and pictures that include intricate color range. One of the cons of using JPG is the loss of details that is encountered every time the file is stored; this points to the fact that the image is marred by clarity issues and a lot of details may be lost. Unlike other file formats such as GIF, transparency is not possible in this format. If you have chosen an innovative image editing program for instance, the Adobe Photoshop, you can pick the image quality and the file size but it is imperative to understand that the lower the resolution the smaller the size, which is easy to upload. PNG: Is an abbreviation for Portable Network Graphics and is a relatively new image format. PNG is provided in two forms; PNG-8 which is the 8 bit color format and the PNG-24 which offers 24 color pictures. PNG-8 can compress pictures with wonderful detail and without the customary loss of data experienced in GIF files; this leads to better picture quality and quick uploads. But, PNG-24 is not as effective as JPG when you want to store photos and other graphics that require a more detailed palette of colors. The image format is sans loss; this means that the photograph retains its crispness and quality. PNG-24 offers transparency support and you can utilize various levels of transparency in this format. In this format the pictures are better looking because they do not have the tell tale jagged edges when pitched on a background with contrasting colors like GIF files.
