Online 3D model viewer: GLB, GLTF and USDZ, in the browser
Drop a GLB, GLTF or USDZ file, spin it, tune the camera, exposure and shadows — then test AR before you ship it.
File facts
Facts apply to local files.
What is Peka AR?
Product photos in, artist-finished 3D + AR models on your storefront, in hours.
What does this viewer do?
An online 3D model viewer renders a model file — usually GLB or GLTF for the web, USDZ for iOS AR — directly in a browser tab. Useful for quickly checking that a model actually matches the product before it goes anywhere near a storefront.
This one adds two things a bare viewer does not: an in-browser AR launch test (does this device support viewing it in your space?) and a file-facts panel (mesh, vertex, material and texture counts, plus file size). Both are computed from the file bytes in front of you — the same numbers you would use when sizing a model for a product page. Shopify's partner guidance, for context, recommends practical web-safe model sizes — roughly 4 MB or less — with mobile textures kept modest.
For an embeddable version of the same experience — one line of HTML, AR buttons, load poster — that is the embed code generator next to it, or the full managed pipeline on the homepage.
How to use it
- Choose a
.glb/.gltf/.usdzfile — or load a demo model — then drag to orbit and scroll to zoom. - Use the Controls panel to sweep camera, exposure, shadows and environment until the preview looks right.
- If the AR button appears, your device can show the model in-room. Use Save PNG for a quick snapshot.
FAQ
What is an online 3D model viewer?
A page that renders GLB, GLTF or USDZ files in WebGL so you can rotate, zoom and inspect a model without installing Blender or a dedicated viewer app.
Do I need to upload the file somewhere?
No. Files you pick stay on your device; the page reads the bytes in memory and renders them locally. Nothing is sent to a server.
Why can USDZ show fewer details than GLB?
USDZ is a ZIP-style archive for iOS Quick Look. The checker reports its name, format and size, but mesh facts inside it are not readable in-browser.
Can I use the result on a storefront?
Rendering a model in a viewer is a separate step from shipping it. For an embeddable, AR-ready viewer tied to your product, that is the Peka AR embed — same model format, one line of HTML.
