Teams designing with luw.ai
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.

GLB is the binary form of glTF: geometry, materials, textures and animation in a single file, which is why it is what most 3D pipelines export for the web. This viewer opens one in your browser — no account, no upload, no watermark — with Draco decoding, PBR materials and animation. Drop a second file in and the two rotate together, so you can see exactly what changed between versions.

How to open a GLB file
- Open your GLB fileDrag it onto the viewer, or click to choose one. Your browser reads it — nothing is uploaded.
- Look at it properlyDrag to orbit, scroll to zoom. Advanced adds auto-rotate, a ground plane, wireframe and any background you like.
- Compare two versionsTurn on Compare and drop a second GLB file. The cameras lock together, so both move as one.
- Save what you seeSave PNG writes exactly the frame on screen, backdrop included, at twice the resolution.
Questions
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.
Does it support Draco compression?
Yes. Draco-compressed GLB files are decoded automatically, as are embedded textures, PBR materials and animation clips.
Can I compare two files?
Yes — that is what Compare does. Load one on each side and the cameras lock together: rotate, pan or zoom one and the other follows exactly, which is the only reliable way to spot a change by eye.
What is the file size limit?
None that we impose — the practical ceiling is your machine's memory. Models in the hundreds of megabytes open fine on a modern laptop.

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.
