The pj file extension is associated with Project64, an emulator for Nintendo 64 games that runs on Microsoft Windows.
A pj file contains a player's progress from an emulated Nintendo 64 game. Project64 uses the file with the corresponding game to restore that progress.
Open the pj file with Project64 on Microsoft Windows. Use Project64's save or load features to restore the stored game progress.
A pj file is an emulator-specific game-progress file and cannot normally be converted to a standard document or media format. To use the progress elsewhere, load it in Project64 rather than converting it.

Bitmap image file
Date updated: September 22, 2026
Printer Command Language, commonly called PCL, is a page description language developed by HP as a printer protocol. This file uses PaintJet-compatible PCL commands and raster data to describe the bitmap that the printer should produce.
The file is intended as printer input, so it may include printing data in addition to the image itself. It is not normally used as an editable source image or as a standard bitmap such as a BMP or PNG file.
HP PaintJet printers and this type of printer data are legacy technology. Modern image applications and operating systems may not provide native support for the format.
The most reliable way to use an HP PaintJet PCL bitmap image file is to send it as raw print data to a compatible HP PaintJet printer. The printer must support the PaintJet PCL commands used by the file.
A PCL-capable rendering or printing application may be able to interpret it, but support for PaintJet-specific files is uncommon.
There is no broadly supported direct conversion path for this legacy printer format. If a PCL-compatible application can render the file, the rendered output may be saved or printed to a more common image or document format.
Converting the file may lose printer-specific information, and simply renaming it does not convert the bitmap data.
