About PI files
The .pi extension primarily identifies a legacy raster graphics file associated with the NEC PC-9800 series, a family of Japanese microcomputers that dominated the market in the 1980s and 1990s. These files typically contain pixel art, game sprites, or interface elements rendered with the specific color palettes (often 16-color or 256-color) native to PC-98 hardware. While historically significant for retro gaming and digital preservation, .pi files present a major drawback today: they are completely unsupported by modern operating systems and standard image editors like Adobe Photoshop. Trying to open them directly usually results in an "unknown file format" error. To make these graphics usable for web display, archiving, or modern editing, they must be converted. The best target format is PNG, which uses lossless compression to perfectly preserve the sharp, blocky aesthetic of the original pixel art without the artifacts introduced by JPG compression. Just drag and drop to determine the format, view, and convert it.

The PI Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PI converter.
