RS to WEBP Conversion: FAQ

What are RS files?

RS is part of a group of formats called Sun Raster Images, developed by Sun Microsystems for use on its UNIX platforms. Similar formats include RAST, RAS and SUN. Files with the RS extension contain bitmaps that were created or processed on workstations or servers developed by Sun Microsystems. They are considered rare and are probably difficult to open via 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.
