Technical note

How CZI and DWG differ in practice

CZI is made of pixels and DWG 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 a DWG 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 CZI to begin with. A CZI file has a pixel count and a DPI value, and no real-world size at all. DWG 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.

Our school uses AutoCAD, but students don't have the software at home. reaConverter lets us convert assignments to PDF so they can review at home. It's affordable, easy to install, and handles batch conversion of 30+ student files in minutes.

I inherited a mess of DWG files from a previous engineer – all in different versions. reaConverter batch‑converted them all to a single, clean DWG format (2018) with no errors. It even fixed some corrupt headers. This tool is a miracle worker.

If you work with AutoCAD, Autodesk, or similar CAD software, you’ve likely faced format compatibility issues. Every developer seems to insist on their own proprietary formats, making conversions a real challenge. The solution? reaConverter. This tool effortlessly handles two-way conversion between dozens of specialized formats!
