When you need to account for quality, JPEG 2000 is a better compression tool. Lossy compression is generally used for video and many images, since theyвЂ™re in the standard JPEG format. Lossy compression reduces a file by permanently eliminating some information, so when the file is uncompressed, only a part of the original information remains.

This is generally what you want to use for text or spreadsheets, where losing words or data could be problematic, even catastrophic. With lossless compression, every bit of data that was originally in the file remains. That means whether or not all original data can be recovered when a file is compressed, then uncompressed. JPEG 2000 offers a single approach to lossless and lossy compression.

And the fact is, there are times to use JPEG 2000, which is why PDF supports JPEG 2000-compressed images. And there are many other use cases, such as biometric applications.Д«ut the venerable format is also used in archiving and business image compression applications. Watching new movies at the theater means youвЂ™re looking at JPEG 2000 pictures, too. If your doctor is doing your radiology pictures in an MRT, those are JPEG 2000 pictures as well. But if you use Google Earth, youвЂ™ll see JPEG 2000 images of your hotel and beach. Therefore, JPEG 2000 wonвЂ™t replace JPEG for digital photos like your vacation pictures. Yet with the passing of time, most photographers have foregone the JPEG 2000 in the same way Betamax was shined on for VHS. Aptly named JPEG 2000, the standard offered better compression performance and superior image quality. In the year 2000, the Joint Photographic Experts Group created what they considered to be the next generation of JPEG image compression. But what about the lesser-known JPEG 2000? Does it have its own uses? The answer is yes.

If youвЂ™ve ever taken a photo with your smartphone or received an image, youвЂ™re aware of JPEG, the standard format for digital photos.
