GRO to WEBP 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 WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
