XCF是eXperimental Computing Facility[1][2]的简称，是 GIMP（GNU图像处理程序,一款跨平台的图像处理软件）保存的图像源文件，具有很多诸如图层的额外特性。也是GNU自由文档许可证与维基共享资源所允许的透明影像格式之一。
该格式类似Adobe Photoshop的PSD文件，支持图层，通道，透明，路径等的储存，不支持撤销历史记录。对保存的图像数据使用简单的RLE算法压缩。
XCF文件可以向后兼容。例如，GIMP 2.0能够文本作为文本图层保存，而GIMP 1.2不能，但GIMP 1.2可以把GIMP 2.0保存的XCF文件中的文字图层当作普通图像层处理。
GIMP开发者不推荐使用XCF作为数据交换格式[3]，是因为
The use of XCF as a data interchange format is not recommended by the GIMP developers,[4] since the format reflects the GIMP's internal data structures, and there may be minor format changes in future versions. The source code of GIMP itself (which is freely available) is the reference documentation of the format. Henning Makholm (see XCFTools below) has written a specification which has been adopted by the GIMP developers. In addition, a collaborative effort between the GIMP developers and Krita developers is underway to design a raster file format called OpenRaster, modelled on the OpenDocument format, for use in both applications in a future version.
支持此格式的软件 [编辑]
除了在GIMP中作为源文件，XCF还可被另外一些软件，如某些图像阅览器与图像转换软件中被读取、使用、导出：
- Seashore是个Mac OS X上基于GIMP的轻量级图像处理软件。
- ImageMagick 有个XCF模块，但仅可读取其单层图像。
- Inkscape 在0.44版后支持导出XCF。[5]
- XnView 可以显示XCF的单层图像。
