Design files are notoriously large and complex, often requiring heavyweight desktop programs to open and review.
For a stakeholder without Photoshop, a .psd is an unopenable file. The PSD viewer renders it in the browser — up to 25 MB, free, no account, no plugin — and deletes it when you close the tab.
What you see is the saved composite — the flattened preview Photoshop writes alongside the layered data — so it is the artwork exactly as the designer last saw it, blend modes and masks already applied.
Be clear about what that does and does not give you. You are not browsing layers here: there is no layer panel, nothing to toggle on and off, and anything the designer left hidden stays hidden. For that you still need Photoshop. What you get is the picture, reliably, on a machine with no Adobe licence.
One useful consequence: type was rasterised into that composite before the file left the designer's machine, so you do not need their fonts to read the small print. Zoom in and check a crop or a caption.
The upload runs over HTTPS, the file is rendered on our servers, and it is deleted when the viewing session ends. There is no account, so nothing is filed under your name and nothing can be retrieved later.
We claim no security certification, and we are not offering storage — so for unreleased campaign artwork under embargo, weigh that up rather than taking "deleted afterwards" as a guarantee about anything but retention.
The interface is deliberately plain: drag the file in, zoom and pan, print with Ctrl+P. Because rendering happens on our servers, a heavy multi-artboard PSD opens on a laptop that could not run Photoshop at all.
The ceiling is 25 MB, and working files do go past it — a layered poster at print resolution reaches that easily. If yours is refused, flattening a copy or saving out the artboard you need is the usual fix.
Open the PSD viewer and upload the file — the billboard mock-up or the social template sitting on your drive.
There is no sharing feature here, so a client sees it by opening the file themselves, which they can do without an account. And for the rest of a designer's awkward formats — EPS, TIFF, SVG, CDR, TGA and camera raw — the vector and raw image viewer takes those, applies embedded ICC profiles, and shows a photograph's EXIF beside it.
