Technical note

ICO to IGS: what to expect from the conversion

ICO is made of pixels and IGS stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside an IGS container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the ICO to begin with. An ICO file has a pixel count and a DPI value, and no real-world size at all. IGS is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

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.
