Convert PFB GRAPHICS to OTB

The PFB (Printer Font Binary) file extension refers to an Adobe Type 1 font used primarily on Windows PCs. Developed by Adobe Systems, PFB files contain fonts in binary format, requiring an associated PFM (Printer Font Metrics) file for proper functionality. Initially proprietary, Adobe later released the specification to third-party font manufacturers. PFB files can also be converted to image files, and AutoCAD utilizes them to create compiled font files.

The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.
