Converting GRO to JPEG

GRO and GRB are image formats associated with a brand of calculators released by HP during the 1990s for advanced mathematical operations. The HP 48 and the HP 49 were both programmable and very popular among science professionals. At the moment, such files are considered uncommon and obsolete, so in case you found an old one on your computer it's probably best to convert it to a more popular extension.

JPG or JPEG is a commonly used method of lossy compression. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the internet.
