"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."

ERF to DGN Conversion: FAQ

What are ERF files?

ERF is the proprietary RAW image format for Epson cameras. An ERF file contains an uncompressed image which can be processed using an advanced image editing software and can be printed using an Epson printer. Many professional photographers prefer to shoot in RAW mode because this allows a better control over the creative editing of the image, and more freedom to customize and transform the image using aspects such as color correction and white balance before converting to a more popular format.

What are DGN files?

DGN stands for "design" and represents an extension typically used for CAD (Computer Aided Design) files created with Bentley Systems' MicroStation or with IGDS (Intergraph's Interactive Graphics Design System) — two popular programs used by architects, engineers, constructors and designers.
