Convert pfb to png8

What is the difference between .pfb and .png8?

Description: A Printer Font Binary (PFB) file is a type of font file used specifically in the context of Adobe Type 1 fonts. It stores font data in a binary format, which includes the glyph shapes and font metrics necessary for rendering text accurately on screens and in print. The PFB file is typically used in conjunction with a metric file (with an .AFM or .PFM extension) that provides additional layout information. This file format was widely used for high-quality typography on PostScript printers.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
