JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. The JPG format is often used in digital camera memory cards. The resultant 'lossy' file means that quality can never be recovered. The range of available GIF colors is from 2 (black and white) to 256 while reducing the number of colors leads to a decrease in the file size.JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved. Reducing the number of colors required to create an image is provided by removing shades unnecessary to perform this process. Scan-line data is compressed to the smallest size. Interlaced data storage is also possible. Thanks to the Lempel-Ziv-Welch algorithm, the format handles graphic files with repeating sections well, particularly images with a large number of single-color pixels horizontally. This ensures the preservation of high-quality pictures. The extension uses the LZW algorithm to carry out a parallel process with the removal of segments containing insufficient information. The format was developed by Compuserve specialists, especially for its use in the web environment, which provided broad public access to data on such files. Many applications open the extension to view and process images and video content installed on PCs and mobile devices regardless of OS. Due to this, it is possible to convert to other formats while preserving the original image properties. The process of compressing files in GIF does not affect the quality in any way, as there is no loss because of the compression technique. They use scan-line images with the depth parameters up to 256 colors of the RGB palette. Such files are used to develop web advertising with sequentially changing pictures and the graphics shell of video files. It also supports transparent views of various animations. GIF, Graphics Interchange Format, is one of the most popular bitmap image formats on the World Wide Web, allowing you to share images. In this case, the reduction in image quality can vary from insignificant to substantial. The file compression ratio is in the range from 10:1 to 100:1. #Jpg to gif animator iso#The format acts simultaneously as the standard of ISO and the International Telecommunication Union. JPEG uses a "lossy" compression system and discrete cosine transform technology. Finally, the colors and brightness are coded. Then it is divided into squares to determine the upper range of the color spectrum. First, the photo is transformed into a color space YCbCr. The procedure for compressing the digital images in JPEG format is carried out in several stages. It is not recommended to use this format to compress drawings and various graphics since a big difference between several near located pixels provokes visible artifacts. The JPEG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present. It is also frequently used in memory cards of digital video cameras. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It uses the technology of encoding smooth color renditions, providing the ability to reduce the amount of data frequently during the image recording. JPEG – is a popular graphic file format, which is characterized by a high degree of compression, which leads to a decrease in image quality.
