JPEG background information

If you are a photography enthusiast, you definitely strive to get photographs of the highest quality. There are different image formats in which you can store your images to achieve this goal. Still, high quality usually means large size, so you still need to optimize your images to post on the web, to send them via e-mail, or to view on different applications. In order to convert images from rare formats into more common ones users start looking for special software like ImageConverter Plus. The format which is most often chosen for that purpose is JPEG. JPEG is a commonly used standard method of lossy compression for photographic images. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG-compressed images will generally look good to human eyes because the image information lost is the information least noticeable to the human visual system. ImageConverter Plus fully supports this format in all of its compression algorithms. When launching ImageConverter Plus and choosing the output image to be of the JPEG format, there are 4 types of compression methods available: baseline, sequential, lossless and progressive. The sequential encoding mode is an extension to the baseline mode, allowing for 12 bit per color components and more Huffman tables. It is the one in which each image component is encoded in a left-to-right, top-to-bottom fashion. The JPEG sequential mode has been very successful in coding images of high and medium bit rates. For low bit rates, the quantization step size needs to be increased in order to get more compression ratio.
