How to Convert Multiple IGES Files to IGS?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed.
2. Load your IGES files
Add IGES files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.
3. Select IGS as output format
Select IGS from the output format list and set your destination folder. You can also adjust quality and compression settings.
4. Start IGES to IGS conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.
When finished, your new .igs files will be waiting in the destination folder.
Before you convert IGES to IGS
IGES and IGS both store drawing entities rather than pixels, so lines, arcs, and text come across as editable geometry. What can be left behind are objects that belong to a specific application, such as proxy entities written by a vertical CAD product. Open the result and check those areas before passing it on.
