Upload Your STEP File
Drag and drop your .step or .stp file into the secure upload area. Our local step to glb converter supports single files up to 200 MiB directly from your device.
Convert STEP to GLB with browser-first processing. If local conversion fails or the export is unavailable in the browser, conversion automatically switches to the server with a private upload; sign-in is required.

Follow these 3 simple steps to transform precise CAD engineering data into a compact, Web-ready format without expensive software like SolidWorks.
Drag and drop your .step or .stp file into the secure upload area. Our local step to glb converter supports single files up to 200 MiB directly from your device.
Supported formats are converted in your browser first, including large models. Conversion automatically switches to the server with a private upload if local conversion fails, or for FBX and USDZ with skins or animation. Server conversion requires sign-in.
Open the export options, choose GLB, and click Export. When the result is ready, click Download to save it.
GLB packages geometry and supported materials; supported animation and skins can be retained. Check the exported result in your target application.

Local previews and browser conversions keep file processing on your device. If local conversion fails or requires the server, the model is automatically uploaded to private storage; temporary uploads and results are cleaned up after 24 hours.

Converting from CAD boundary representations (B-Rep) to polygonal meshes can result in data loss. Our tool diligently extracts available face color data from the STEP model, automatically mapping it into standardized GLB object materials.

Supported formats are converted in your browser first, including large models. Conversion automatically switches to the server with a private upload if local conversion fails, or for FBX and USDZ with skins or animation. Server conversion requires sign-in.

Open 3D models for a local browser preview. Local file previews stay in your browser without sign-in. Supported formats are converted in your browser first, including large models. Conversion automatically switches to the server with a private upload if local conversion fails, or for FBX and USDZ with skins or animation. Server conversion requires sign-in.

Describe it, generate it — create 3D models straight from text prompts.
Convert STEP to GLB with browser-first processing. Conversion has no additional fee. Local file conversion does not require sign-in; server conversion does. Generation usage and existing download entitlements for generated assets still apply.
