A newsletter or article to be published on the Web of course will be constantly more complete and clearer if added to the picture. Visitors will certainly feel at home because of an article can be impressed and not monotonous only from a text.

But as the owners of the Web is, of course we must pay attention to image quality and size of the image. With the aim of drawing a quality color and good light but size is small, so that Web pages remain still fast to accessing and could be seen clearly by the visitors, another reason would save space and bandwith hosting of course.

JPG or JPEG (Joint Photographic Experts Group)

This format is suitable for pictures with color combinations are many and complex, such as landscape photography and so on since it contains a 24-bit color. Therefore, this format most commonly used in the world of photography.

Given the relatively small file size with good quality equipment. If you want to display images with complex color combinations, and wanted to keep the quality of the display, then this format is the best option. Only, this format does not support transparency.

GIF (Graphic Interbhange Format)

Is a widely used format for the Web, even the Web has become a standard format that has been introduced since 1987. Although this format can contain a veriety of 24-bit color (about 16 million different colors), but a Gif image can only have as many as 256 combinations of colors (8-bit-per-pixel), so for images with many color combinations such as photos, when converted to GIF format will look broken.

This format is suitable for files with a limited color display and simple, like drawing with a block certain colors, lines, and text. The advantages of this format can be used to save the animation, so it’s still often used for Banner Ads. Because of licensing problems compression is used, hence made a substitute format GIF format is PNG format.

PNG (Portable Network Graphic)

Starts due to problems licensing the GIF format, PNG format then be made of this. Initially PNG support is still limited, but from now all browsers already support this format. Unlike GIF, this format can store 24-bit color combinations, not limited to just 256 colors. Resulting file size is relative smaller than the GIF format.

There are many advantages over the GIF format, PNG can not only save the animation, though there are silimar for animation formats, namely MNG. In addition, older browsers such as Internet Explorer 3 and earlier (if there is wear) do not support this format.
