What is a PSZ file?
The .PSZ file extension usually belongs to a Photogrammetry Project Archive created by Agisoft Metashape. Professionals use this software to generate 3D spatial data from 2D digital images. The .PSZ file contains the complete project data, including 3D models, textures, and point clouds. Internally, these files use standard ZIP compression to store multiple files and folders in one single package.
A secondary use for the .PSZ file extension is a compressed game asset or 3D model file, often found in older PlayStation 2 games or titles using the Illusion Soft game engine. Rarely, it can also represent a Compressed PostScript File, which holds encoded print documents.
How to open PSZ files?
To open a photogrammetry project, you need Agisoft Metashape. Because the primary format uses standard compression, you can also rename the .PSZ extension to .ZIP and extract the contents using archive utilities like 7-Zip or WinRAR. If the file is a PlayStation 2 game asset, users typically rely on community-built extraction tools or a specialized PSZ Viewer.
Software and tools
Because a .PSZ file has multiple possible meanings, you might not know which software to use. viewer.online/psz analyzes .PSZ files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because many .PSZ files use the known ZIP format, viewer.online/psz can safely open and display them online, eliminating compatibility problems.
