glTF to GLB Converter

Package a contained glTF 2.0 model and its resources into one self-contained GLB.

Upload STL, PLY, or GLB directly. Use a ZIP for OBJ/MTL/textures or glTF resources. Direct self-contained OBJ and glTF files are also accepted. Limit: 1 GB.

What each format can retain

STL contains triangle geometry only. OBJ/MTL adds UVs, normals, simple materials, and external textures. PLY commonly stores geometry and vertex properties. glTF and GLB can retain modern scenes, PBR materials, skins, morph targets, and animation when the engine can represent them.

No repair or quality reduction claims

Conversion does not claim to repair a model, make it watertight, preserve CAD precision, or make it ready for 3D printing. Geometry is never decimated and textures are never resized to control server load.

glTF to GLB Converter

Bundle a glTF 2.0 document and its contained local resources into one self-contained GLB.

Input
A glTF file with its local buffers and textures in an accepted package.
Output
One GLB file and a resource-fidelity report.
Real limitations
External HTTP resources are never fetched, missing local resources are rejected, and unsupported extensions may not survive the bundle.
Privacy and data handling
a glTF file with its local buffers and textures in an accepted package is uploaded to a compatible Convertr worker only after you start the operation. Processing is automated, and temporary source and result files are deleted automatically after processing rather than retained as permanent storage.

How to use this tool

  1. Choose a glTF file with its local buffers and textures in an accepted package and wait for the page to validate it.
  2. Set the available output or inspection options, then start processing.
  3. Review the reported result and download one GLB file and a resource-fidelity report before the temporary link expires.

Common failure modes

A missing .bin file, unsafe relative path, invalid JSON, or incompatible glTF version causes the bundle to fail.

Useful example

Upload scene.gltf with scene.bin and local PNG textures to download scene.glb.
