STL to GLB Converter

Convert an STL into a compact GLB (binary glTF) — the standard format for showing 3D models on the web and in AR. GLB loads fast in browsers, model-viewer, three.js, and Google/Apple AR Quick Look.

Converting STL to GLB in practice

STL to GLB is how a 3D model gets onto the web and into AR. GLB is the compact binary form of glTF — often called “the JPEG of 3D” — and it is what powers model viewers on a product page, Sketchfab embeds, and the “view in your space” AR buttons on phones. STL is far too heavy and featureless for that.

Convert here when you want to embed a model in a website, share an interactive preview, or drop an object into AR. GLB bundles geometry and, where present, materials into one small file that browsers and phones render instantly, with no plugin needed.

When to convert STL to GLB

  • Embed a 3D model on a website with <model-viewer>
  • Use a print model in a three.js or React-Three-Fiber scene
  • Preview a design in AR on a phone

About the STL and GLB formats

How it works

How to convert STL to GLB

  1. Upload or paste a STL link

    Drop a STL file from your device, or paste a public URL pointing to the STL you want to convert.

  2. Confirm GLB as the output format

    The output is pre-set to GLB. You can adjust quality or bitrate in the advanced options if you need a smaller file.

  3. Start the conversion

    Click Convert. Our cloud workers fetch the STL, scan it for malware, and run the STL → GLB pipeline.

  4. Download your GLB file

    A one-time pre-signed link appears as soon as the GLB is ready. The file is automatically deleted from our storage 2 hours later.

STL to GLB — Frequently asked questions

Yes — GLB opens in any glTF viewer, the <model-viewer> web component, three.js, and Windows 3D Viewer. STL has no materials, so the GLB shows the bare mesh, which you can texture later.
