How do I open a .PSD file?

Drop a .PSD file onto Analyser at https://lab.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open Adobe Photoshop documents (PSD and PSB) in the browser: the flattened composite image Photoshop bakes in is shown, plus the full layer tree with each layer name, blend mode, opacity, visibility and a per-layer thumbnail. Reads the canvas dimensions, colour mode and bit depth. Files saved without Maximize Compatibility have no composite, so their layers are shown instead.

Can I open a .PSD file online for free?

Yes. Analyser is a free online .PSD opener and viewer that runs entirely in your browser - your .PSD file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.
