Reads a Photoshop document's dimensions, color mode, layer names, and the embedded thumbnail preview, if Photoshop saved one.
Being handed a .psd without owning Photoshop is common — this shows what's inside without needing the app.
Drop a .psd file. Document info, the embedded thumbnail (if present), and the layer list all appear immediately.
Read-only, and doesn't composite or render the full layered image — only the embedded thumbnail, if one was saved with the file.
