These are the handy ones. Here is the engine behind them.

250 million designs generated, 3 million designers, and teams from Airbus to Arup working in it every day. The viewers on this page cost nothing and always will — they are ours to give. This is what the same team builds when nobody is limiting it to one file.

It stays on your machineThe file is read by your browser. No upload, no queue, no account — you can pull the network cable and it still works.
Two files, one cameraCompare puts versions side by side and locks the cameras together. Move one, the other follows — the only way to catch a change by eye.
The numbers you opened it forTriangles, vertices, materials and real-world dimensions, read from the file itself the moment it lands.

What a glTF file is

glTF is the format the web agreed on: a JSON scene description with geometry and textures either alongside it or embedded. This viewer renders it with physically based materials and studio lighting, in your own browser. A .gltf that points at separate texture files needs those files embedded — export as .glb if you want one self-contained file.

How to open a glTF file

  1. Open your glTF fileDrag it onto the viewer, or click to choose one. Your browser reads it — nothing is uploaded.
  2. Look at it properlyDrag to orbit, scroll to zoom. Advanced adds auto-rotate, a ground plane, wireframe and any background you like.
  3. Compare two versionsTurn on Compare and drop a second glTF file. The cameras lock together, so both move as one.
  4. Save what you seeSave PNG writes exactly the frame on screen, backdrop included, at twice the resolution.

Questions

What is the difference between glTF and GLB?

They hold the same scene. .gltf is JSON, usually with textures and geometry in separate files next to it; .glb packs all of it into one binary file. GLB is the one to send to someone else.

My .gltf loads without textures. Why?

Because the textures are separate files the browser was never handed. Re-export as .glb, or as a .gltf with embedded resources, and they travel with it.

Is my file uploaded anywhere?

No. It is read and rendered by your own browser and never leaves your machine. You can disconnect from the internet once the page has loaded and the viewer still works.

No account, no watermark, no upgrade prompt hiding in it — this viewer is finished and it is yours. When the work gets bigger than one file, the same engine turns a photo into a floor plan and a sketch into a render, and 3 million designers already work that way.
