- Description
 - The PLT file extension is a vector-based plotter file developed by Autodesk, Inc. to contain plotting details from a certain CAD or computer-aided design file.
 - Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
