How to Open a .PSD File

Why this file may not open automatically:A PSD is a project file, not a picture. Where a JPG saves a single grid of pixels — the finished look, nothing more — a PSD saves the ingredients and the recipe: every layer, how the layers blend together, the masks, the adjustment layers, the text with its font settings, the smart objects that hold the original unscaled artwork. That layered recipe is Photoshop's private language, which is why generic viewers either refuse the file or show only a rough guess. To make life easier for everyone else, Photoshop can bake a flattened composite image into the file — a preview of the finished design that other programs can display. That setting is called Maximize PSD and PSB File Compatibility, and it is exactly what macOS Preview, Quick Look, and most lightweight viewers rely on. If the file was saved without it, those one-glance viewers show nothing at all. Free editors like Photopea and GIMP go further by reading the layers themselves, but even they have honest limits: adjustment layers may not behave the way Photoshop renders them, smart objects may lose their editability, and text usually arrives rasterized — converted to plain pixels — because the font settings don't always translate. So the practical rule is this: if you want to look at the design, almost any free method works. If you want to edit the layers, use Photopea in your browser for the best fidelity. And if you later send an edited file back to a Photoshop user, check it looks right first — round-tripping through another editor can shift fine details.
