IFC GUID Checker

Detect duplicate GUIDs in your IFC files. Compare GUIDs across multiple IFC files to spot potential conflicts. GUIDs (Globally Unique Identifiers) should be unique across all elements in your BIM project.

Purchase the full version to check across more than 2 files.
Free version limited to 2 files only and have 200 MB file size limit.

This tool does not upload your files to any server. All processing is done locally in your browser.

Basic telemetry data is collected to help improve the tool, but no file data or GUIDs are transmitted:

  • Time taken to process files
  • Number of files processed
  • Number of duplication
