"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

SUL to DCX Conversion: FAQ

What are SUL files?

SUL is an old and obsolete image format file associated with GFA RayTrace — a program designed for Atari ST computers. The software was released in the late 1980s and allowed users to operate with 3D objects in an incipient stage, usually implying a lot of time for required calculations. SUL files are now considered rare, so opening them probably requires conversion.

What are DCX files?

DCX files are multi-page images consisting of raster graphics, usually used to create fax files and functioning as a header that introduces a series of ensuing PCX files. DCX is a bitmap format and was initially developed together with the PCX format by Zsoft Corp. and was associated with PC Paintbrush.
