GRO to JXR Conversion: FAQ

What are GRO files?

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.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression.
