Having trouble uploading your GLB/GLTF files? Here are the most common issues and how to resolve them quickly.

Upload Requirements

  • File types: .glb, .gltf (with associated .bin and texture files)
  • Maximum size: 500MB per file
  • Supported browsers: Chrome, Firefox, Safari, Edge (latest versions)
  • Internet connection: Stable connection required for large files

Common Upload Issues

Upload stalls or times out

Possible causes: Slow internet, large file size, browser issues

Solutions: Check your connection, try a different browser, reduce file size

"File type not supported"

Possible causes: Wrong file extension, corrupted file

Solutions: Ensure .glb/.gltf extension, re-export from 3D software

Upload button not responding

Possible causes: JavaScript disabled, browser compatibility, ad blockers

Solutions: Enable JavaScript, disable ad blockers, try incognito mode

Reducing File Size

If your file is too large, try these optimization techniques:

  • Compress textures to JPEG (for non-transparent areas) or WebP
  • Reduce texture resolution (e.g., 2048x2048 instead of 4096x4096)
  • Simplify geometry by reducing polygon count
  • Remove unused materials and textures
  • Use Draco geometry compression in your exporter
  • Split large models into smaller parts

Browser-Specific Issues

Chrome/Edge

  • • Clear browser cache
  • • Disable extensions
  • • Check for updates

Firefox/Safari

  • • Enable JavaScript
  • • Clear cookies
  • • Try private browsing
