− | {{w|JPEG 2000|JPEG2000}} is a standard for digital image storage created by the Joint Photographic Experts Group from 1997 to 2000 to improve on the original {{w|JPEG 2000|JPEG}} standard, published in 1992. The original JPEG standard is the most widely used image format in the world for both digital cameras and the World Wide Web, while the newer and improved JPEG2000 standard is relatively rare. As of 2020, it is supported by Photoshop, the Safari browser, and GIMP, but it remains unsupported or poorly supported by other popular software, including Google Chrome and Mozilla Firefox browsers. Meanwhile, competing format {{w|WebP}} which appeared 10 years later is supported in all major browsers and has much wider support in other applications as well. | + | {{w|JPEG 2000|JPEG2000}} is a standard for digital image storage created by the Joint Photographic Experts Group from 1997 to 2000 to improve on the original {{w|JPEG 2000|JPEG}} standard, published in 1992.

As a result, the conventional file name extensions for files using the JPEG2000 standard, .jp2 and .jpx, remain unfamiliar to many users while the .jpg extension, denoting the original standard, is well known. | As a result, the conventional file name extensions for files using the JPEG2000 standard, .jp2 and .jpx, remain unfamiliar to many users while the .jpg extension, denoting the original standard, is well known. | ||
The JPEG2000 standard was seen as an improvement by its creators, supporting many features not included in the original standard, such as multiple resolutions, progressive transmission, a lossless compression option, and alpha channel transparency. The complexity of fully implementing the standard, as well as patent concerns, may have slowed adoption. | The JPEG2000 standard was seen as an improvement by its creators, supporting many features not included in the original standard, such as multiple resolutions, progressive transmission, a lossless compression option, and alpha channel transparency.
