Convert GIMP XCF to Photoshop PSD

XCF (eXperimental Computing Facility) is the native project file format for the GNU Image Manipulation Program (GIMP). It is a binary format designed to save all data associated with a GIMP editing session, including layers, channels, paths, transparency (alpha), and guides. The file structure relies on a pointer-based system to reference image tiles and uses simple Run-Length Encoding (RLE) for compressing pixel data. XCF is strictly a working format for image editing and is not intended for final image distribution or web rendering.

The XCF format is proprietary to GIMP and should be opened using the GNU Image Manipulation Program on Windows, macOS, or Linux to preserve layer structure and editability. While some third-party viewers like IrfanView (with plugins), XnView, and Inkscape can import or view flattened versions of XCF files, they cannot write or edit the multilayered data natively. Operating systems do not provide native rendering support for XCF files.

The Photoshop Document (PSD) is the proprietary file format of Adobe Photoshop, capable of storing an image with support for all available imaging options including layers, adjustment layers, layer masks, alpha channels, paths, and vector text. It utilizes Run-Length Encoding (RLE) for compression and allows for a maximum file size of 2 GB and dimensions up to 30,000 pixels. The format maintains the editing history and non-destructive elements of a project, unlike flattened raster formats. The internal structure is divided into five parts: File Header, Color Mode Data, Image Resources, Layer and Mask Information, and Image Data.

Adobe Photoshop is the primary software for full PSD support. However, several other programs offer varying degrees of compatibility. GIMP (GNU Image Manipulation Program) and Paint.NET (with a plugin) can open PSD files but may not render complex layer styles or adjustment layers correctly. CorelDRAW and Affinity Photo also provide robust support. For simple viewing without editing, standard image viewers like XnView or IrfanView can often display the flattened composite preview embedded within the file.
