RAS to WEBP Conversion: FAQ

What are RAS files?

The RAS file extension represents the CALS Raster File Format, a standard developed by the U.S. Department of Defense for the interchange of monochrome raster graphics. It is primarily used for storing high-resolution, black-and-white images such as engineering drawings, technical manuals, and scanned documents. CALS RAS files are typically used in military, aerospace, and government applications due to their consistency and archival suitability. The format supports compression and is optimized for printing and long-term storage.

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.
