The XCF file format is the native image format used by GIMP (GNU Image Manipulation Program), a free and open-source raster graphics editor used for image editing, free-form drawing, converting between different image formats, and more specialized tasks. XCF stands for eXperimental Computing Facility, which was the name of the lab where GIMP was originally developed. XCF files are designed to store all the information that GIMP needs to accurately render an image.
It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
