"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

GRB to MIF 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 MIF files?

The MIF extension can be associated with vector images under the MapInfo Interchange Format, in which case it consists of a map and a database exporting file. Also MIF or MIFF file format represents a raster image associated with ImageMagick. This open source program is specialized in editing images, and it is mostly popular among developers as it doesn't have an advanced graphical user interface, so it can mainly be used under command-line. reaConverter supports both types of MIF formats and can convert to vector MIF if the source file is also a vector, and to raster if the source file is a raster image.
