Even though JPG & J2K are similar formats, there are a few differences between the two. First, we’ll learn about the JPG format.

The JPG format is a raster image format which has quite lossy compression but is a preferred file format. It is used by digital cameras & other devices majorly for photography.

Users change their images from JPG to J2K because of the new features.

JPG has been in use since a long time but J2K was started being used in 2000. It is capable of offering both lossy as well as lossless compression.

In terms of quality, J2K has better compression & the quality & content is, thus, richer than JPG format.

It has the option for decoding with different output resolutions and the process to calculate the bit rate can be performed.

You can segregate the image into smaller parts which can be independently coded.
