reaConverter installs quickly on any Windows PC. No dependencies, no bloatware — just a clean setup that's ready to use immediately. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your CR3 files
Load your CR3 files into reaConverter. You can add individual files or point to folders, and the software will queue everything automatically.
Drop your CR3 files into the window or use File menu to browse and select folders.
3. Select IGES as output format
Select IGES from 700+ supported output formats. Choose your destination folder and adjust settings to match your needs.
4. Start CR3 to IGES conversion
Hit Convert and let reaConverter do the work. The progress window shows status for each file in real time.
After conversion, find your IGES files in the output folder. Click 'Show converted files' to open it directly.
CR3 to IGES: what carries over and what does not
CR3 files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to IGES bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. CR3 is made of pixels and IGES is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a IGES container, and that determines whether a CAD or design tool can work with it.
