If your compression is failing, here are the most common causes and solutions to get your GLB/GLTF files compressed successfully.

Common Error Messages

"File format not supported"

Cause: The uploaded file is not a valid GLB or GLTF file.

Solution: Ensure your file has a .glb or .gltf extension and is properly formatted.

"File too large"

Cause: The file exceeds the 500MB size limit.

Solution: Reduce file size by optimizing textures or geometry before uploading.

"Corrupted file data"

Cause: The file contains invalid or corrupted data.

Solution: Re-export the file from your 3D software or validate it with our glTF validator.

Troubleshooting Steps

  1. Verify your file is a valid GLB or GLTF format
  2. Check that file size is under 500MB
  3. Try uploading with default compression settings first
  4. If using custom settings, reduce compression intensity
  5. Validate your file structure using our glTF validator
  6. Re-export from your 3D software if issues persist

Prevention Tips

  • Always test files in our glTF validator before uploading
  • Use the latest export plugins for your 3D software
  • Optimize textures and geometry in your source file
  • Avoid extremely complex shader setups
  • Keep file paths and names simple (no special characters)
