The .psd is design's native tongue and nobody else speaks it: your file manager shows a blank icon, your image viewer shrugs, and the design you were sent might as well be encrypted. Meanwhile all you wanted was to see it — or drop it into a doc. There is a thirty-second answer that involves installing nothing.
The thirty-second flow
- Open PSD to PNG (or PSD to JPG for a smaller file).
- Drop the .psd. The flattened design is decoded in your browser.
- Preview it right in the page, download at full resolution.
Decoded on your device — unreleased designs never touch a server.
What a PSD actually is
Layers, masks, effects and — in most files — a pre-rendered "composite": the finished image, baked in so other software can display it. That composite is what this conversion extracts, which is why the result looks exactly like the design and why no Photoshop features need re-implementing. It is also why the rare file saved without a composite ("Maximize compatibility" off) cannot convert — there is nothing baked in to extract.
After the conversion
The PNG behaves like any image: compress it for email, resize it for a doc, or wrap it in a PDF for a client. If what you actually need is to reuse a logo from the design at any size, ask the designer for the SVG — and when they send it, the whole SVG toolbox here speaks that language natively.
