KiSS CEL is a raster image file format associated with Kisekae Set System, a game(?) that involves making computerized "paper" dolls. Much of the information about it is in Japanese.
Its name has many variations. "KiSS" may instead be "KIS" or "KiSS/GS" (GS is the name of the specification), "CEL" may instead be "cell", and the words may be capitalized in any conceivable way.
The original KiSS graphics format uses two files for each image: a .CEL file containing the bitmap, and a (possibly shared) .KCF file containing the color palette. KCF files are also known as KiSS color files.
The original KiSS CEL format supports 4- and 8-bit paletted images, with binary transparency. A newer version of it called Cherry KiSS (CKiSS) supports 32-bit RGBA images, and does not use a KCF file.
CEL and KCF files all begin with a 32-byte fixed header.
CEL and KCF files begin with a 4-byte ASCII signature: "
- 4-bit CEL files have bytes
- 8-bit CEL files have
- CKiSS files have
- KCF files have

- GIMP [Ed. note: We could not confirm that GIMP correctly writes CEL files.]
- XnView (Apparently requires the KCF file to have the same base filename as the CEL file.)
