A .jng file is an image saved in the JPEG Network Graphic format. The JNG format is similar to the JPEG (.jpg) format, except it supports transparency. For this reason, JNG is often compared with PNG (.png), which is the primary format used to save images with transparency.

Most image viewers and editors cannot open JNG files. To use JNG files more easily, you can convert them to JPEG or PNG. If your JNG file contains transparent or semi-transparent sections, you should convert it to the PNG format, to retain its transparency.
