ST4 to WEBP Conversion: FAQ

What are ST4 files?

An ST4 file represents a RAW image taken with an SBIG CCD camera. SBIG is a producer of astronomical instruments and ST4s most likely contain images related to some type of scientific or industrial application. They are considered rare and are probably 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.
