PSB Viewer - Open Large Photoshop Files on Android & Online

PSB is Adobe’s Large Document Format - the version of the Photoshop file made for images that outgrow PSD, with dimensions up to 300,000 pixels and file sizes that can reach many gigabytes. Billboard artwork, panoramas and print masters ship as PSB, and no Android phone opens a file like that on its own.

Server-side rendering removes that limit. GroupDocs.Viewer Cloud processes the heavy file on its own machines and sends your device only lightweight HTML, PDF, JPG or PNG output, so you inspect the artwork with zoom and navigation while the original file stays in cloud storage.

When a studio sends you a PSB for approval, the free online GroupDocs.Viewer app is the simplest option: upload the file from your mobile browser and review the composition right away.

Developers who handle design assets can add the same rendering to an Android app with the REST API and its Java SDK, installed by Gradle or Maven and documented with samples. Password-protected files are served too, alongside more than 180 other formats, and an evaluation fits inside the free trial, with the API Explorer for trying calls.
