GRB to PDF Conversion: FAQ

What are GRB files?

GRB is a raster image format associated with two calculator models produced by Hewlett Packard in the 1990s: the HP 48 and the HP 49. Both could be used for advanced algebraic operations and calculations and were considered innovative at the time of their release. GRB images most likely contain screen caps or other type of data connected to these devices. They are rare and difficult to open with regular image viewers.

What are PDF files?

PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics.
