RAS to PNG 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.
