Some of the commonly used file types for pictures are GIF, JPEG and PNG, all of these formats boasts of a fair share of advantages so lets talk about the advantages and disadvantages of utilizing these file formats, the type of file that would meet the expectations your website and optimizing your images for the web usage. GIF: It is the abbreviation for Graphics Interchange Format; the image format is one of the more well known file types. The image format is well accepted because of its tiny image size which makes uploading a breeze. But like in the JPEG format, data is not lost in this format ; this equates to the fact that you can store the file without using up a lot of space and compromising the image quality. The format is also known to support transparency in graphics, it is by far the most commonly used image formats for picture 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 important to keep the size of the image small; it would be best that you pick a 32 color palette to get a suitably small size. JPEG: This is the abbreviation for Joint Photographic Experts Group; the file type is generally called JPG and is often seen on websites. One of the primary pros of using this type of image is that you can save the graphics in true color that gives you as many as 16 million colors; this renders the image type ideal for saving photos and graphics that have detailed color work. One of the problems of utilizing JPG is the data loss that you will have to deal with each time the file is saved; this points to the fact that the image is susceptible to clarity issues and some data may be lost. Unlike the GIF format, support for transparency is not provided in this format. If you are using an advanced image editing software like the Adobe Photoshop, you will be able to select the image quality and the size of the JPG file but it is imperative to realize 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 fresh file type. This format is offered in two versions types; PNG-8 which is the 8 bit color format and the PNG-24 which offers 24 color pictures. PNG-8 can compress pictures with fantastic detail and without the customary loss of data observed in in GIF images; this gives improved picture quality and quick uploads. But, PNG-24 is not as efficient as JPG when you have to store pictures and other images that require a vaster palette of colors. The image format is loss-less; this means that the image retains its clarity and quality. PNG-24 supports transparency and you can include various levels of the transparency feature in this file format. In this format the graphics are smoother because you cant see jagged lines when pitched on a contrasting background like GIF files.
