What is a PSG file?
A .PSG file is a shared file extension used by several different software applications. Because multiple developers chose this same extension, a .PSG file can contain completely different types of data. Common uses include PlayStation 3 game graphics, IBM Advanced Function Presentation (AFP) page segments, and GLOSSA programming code used by the Greek Ministry of Education. Other applications also use the .PSG extension, such as Adobe Photoshop for layer groups, PVsyst for solar grid designs, and older software like Broderbund Print Shop Deluxe.
How to open PSG files?
To open a .PSG file on your computer, you must first know which program created it. If the file is a solar grid project, you can open it with PVsyst. If it is an image layer group, you can use Adobe Photoshop. If the file contains GLOSSA pseudocode, you can view it in a standard text editor. Enterprise users handling IBM AFP page segments typically use specialized printing infrastructure or document management tools from companies like Elixir Technologies.
Best practices and troubleshooting
The biggest challenge with .PSG files is format confusion. Opening a PlayStation 3 graphic in a text editor will only show scrambled characters. Trying to open a GLOSSA source file in an image viewer will cause an error. Because of this overlap, you should never blindly assign a default application to the .PSG extension on your computer. Always verify the file origin first.
Software and tools
- Adobe Photoshop (Graphics and layer groups)

Summary
If you do not know the origin of your file, viewer.online/psg can analyze .PSG files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. Because this extension has multiple possible meanings, viewer.online/psg is useful for identifying, inspecting, and understanding .PSG files without installing software or dealing with compatibility problems.
