PSD

PSD is the native working format for Adobe Photoshop, storing a document's full layer stack — including adjustment layers, smart objects, masks, and layer styles — in a proprietary binary structure. Because it preserves every editable element, PSD files are typically far larger than flattened exports. The format has not been publicly specified, but Affinity Photo and GIMP both provide substantial PSD compatibility, making it a de-facto interchange format for layered photo editing workflows.
