How to use glTF / GLB Converter
Packing handles only local dependencies explicitly provided by the user and does not fetch remote URLs. Unpacking creates multiple files whose paths must stay intact.
- Choose a conversion direction.
- For glTF to GLB, provide JSON, bins, and local textures together.
- Review missing URIs, MIME types, extensions, and preview.
- Download GLB or a resource ZIP and reload it in the target environment.
What this tool helps with
- Move between a single file and editable resources
- Reports missing dependencies before conversion
- Processing runs in this browser tab; the file is not uploaded to FreeTool to perform the task.
Compatibility and limitations
- Remote, authenticated, or missing resources are not fetched automatically
- No automatic mesh or texture compression
- Custom extensions may only be preserved or reported unsupported
Frequently asked questions
Why is a .bin missing?
glTF JSON references binary data, so the matching local file must be supplied.
Will conversion reduce size?
Format conversion is not compression and size is normally similar.
