How to Convert Multiple GLB Files to STP?
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 GLB files
Load your GLB files into reaConverter. You can add individual files or point to folders, and the software will queue everything automatically.
Select GLBs from a folder or drag-and-drop them directly into the reaConverter window.

3. Select STP as output format
Choose STP for output and set your save location. reaConverter lets you customize quality and apply edits before conversion.

4. Start GLB to STP conversion
Press the Convert button and reaConverter takes care of the rest. Processing time depends on file size and volume.

After processing, find all your new .stp files in the output location. The log shows details for each conversion.
What changes when you convert GLB to STP
GLB stores a surface made of triangles, while STP is built for exact solid geometry. The conversion has to derive surfaces from that triangle mesh, so the result is faithful to the shape but is not the same thing as a parametric model with clean features and editable dimensions.
