GRB to GIF 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 GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
