HPI to WEBP Conversion: FAQ

What are HPI files?

HPI is a rare image format associated with some software programs developed by Hemera Technologies, such as Photo Clip Art or BizArt. HPI files are similar in size and functions with JPG and PNG. However, they are less common and for this reason they might be more difficult to open using regular image viewers.

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.
