XCF to JPEG Converter

XCF (eXperimental Computing Facility) is the native file format of GIMP) (GNU Image Manipulation Program), named after the computing facility at UC Berkeley where Spencer Kimball and Peter Mattis originally developed GIMP as a student project, with the format introduced alongside GIMP 1.0 in 1998. XCF stores the complete editing state of a GIMP project: all layers with their positions, dimensions, opacity, and blending modes; layer masks; channels (including custom alpha channels); paths (vector shapes stored as Bezier curves); parasites (arbitrary named data attached to the image or individual layers); and the image's color profile, resolution, guides, and grid settings. The format supports 8-bit, 16-bit, and 32-bit floating-point precision per channel in RGB, grayscale, and indexed color modes, and uses a tile-based internal structure where the image is divided into 64x64 pixel tiles that are individually RLE-compressed. Each layer in an XCF file is stored independently with its own dimensions (layers can be larger or smaller than the canvas), enabling non-destructive editing workflows where source material is preserved at full resolution. One advantage is complete state preservation: XCF files save everything needed to resume editing exactly where you left off — every layer, mask, path, and setting — making them the essential working format for any multi-session GIMP project. The format's open specification is another strength: the XCF structure is fully documented and readable by GIMP, XnView, ImageMagick, and various programming libraries, ensuring project files remain accessible without vendor lock-in.
