STEP to GLB

Convert your STEP file to GLB, right in the browser.

Model workspaceSTEP / STP → GLB

Your model goes here.

Choose your file or try the original sample below. No installation or sign-up.

01 / HOW IT WORKS

Open, inspect, then use your result.

  1. 01

    Open your file

    Choose, drop or paste your STEP file. All three input methods use the same local checks.

  2. 02

    Look from every angle

    Orbit, zoom and switch between standard views. Read the dimensions and object count beside the model.

  3. 03

    Download the converted file

    After conversion, download GLB. Open the result in your destination software and check the units before use.

02 / TRY IT YOURSELF

A real file. A result you can check.

This original four-hole plate measures 80 × 50 × 8 mm. The sample uses the input format for this page. Use the default unit and axis settings to reproduce those dimensions.

03 / FORMAT & USE

STEP to GLB

Create a compact binary glTF model for web viewers and 3D presentation. The CAD engine tessellates STEP solids into a self-contained GLB with metre-based coordinates and Y up.

What this viewer supports

The result is a display mesh, not an editable CAD solid. Original part names, assembly hierarchy, colours and feature history are not restored by STEP import.

STEP and STP solid models up to 32 MiB and 2,000 solids. The converted geometry must also fit a 16 MiB internal limit, so file size alone does not guarantee a model will open. Complex models may exceed the time or memory budget.

04 / QUESTIONS

Know your input. Understand your output.

Why does a metre-based GLB look smaller in a CAD application?

GLB uses metres. A 100 mm part is 0.1 units wide in GLB. Use the destination software’s metre import option rather than changing the geometry.

Do I need an account or credits?

No. These tools are free and run in your browser. No account, subscription or credits are required.

Is my model uploaded?

No. Your selected file is read and processed in this browser. The page downloads its CAD engine and public samples, but does not upload your model. Refreshing or leaving the page clears the current file from the tool.

How are units and orientation handled?

The overall bounds come from the imported solid geometry and are shown in millimetres. They are not point-to-point measurements or drawing tolerances. If the declared units are unknown, check a known dimension before relying on the result.

Can I paste a file from my computer?

Copy a file in your file manager, then paste here. Your browser must expose the clipboard as a file; a copied path or text will not open a model.
