Convert a file to PNTG

To convert other file formats to the "Legacy MacPaint Graphic File" file type, you need software like Apple MacPaint or a similar tool.


About PNTG files

The .PNTG file extension is a legacy MacPaint Graphic file format developed by Apple for the original Macintosh in 1984. It stores 1-bit monochrome (black and white) raster images using PackBits compression. The canvas is strictly limited to 576 × 720 pixels. Historically, users opened these with Apple MacPaint, but today, specialized software like GraphicConverter or XnView is required to read the bitmap data.

You need to convert this file because modern web browsers, operating systems, and standard image editors like Adobe Photoshop cannot read .PNTG natively. The format is completely obsolete, completely lacks color support, and is restricted by its rigid resolution.

For web and general use, convert to PNG. PNG perfectly preserves 1-bit pixel data losslessly without introducing compression artifacts. For archiving or print workflows, convert to TIFF. Drag and drop your .PNTG file here to analyze and convert it - free, online, and without installing legacy software.
