How to View a GLTF File Online
Open and explore any GLTF model in three simple steps no software install and no signup needed.
Upload Your GLTF File
Drag and drop your .gltf file or click to browse. Your GLTF model, up to 50MB, loads instantly right in the browser.
View & Interact
Your GLTF model loads in seconds. Orbit, pan and zoom with your mouse or touch to inspect it from every angle in real time.
Inspect Every Detail
Toggle the reference grid, reset the view and zoom in to check geometry, proportions and surface detail.
Why Use the Vega3D GLTF Viewer
A fast, private and free way to open GLTF files right in your browser.
Your Files Stay Private
Your GLTF files are loaded and rendered locally in your browser and never uploaded to a server, so your models stay private.

Questions
glTF (GL Transmission Format) is an open, JSON-based 3D standard often called the “JPEG of 3D”. It is efficient and built for real-time and web applications.
Drag and drop your .gltf file onto the viewer or click to browse. It renders instantly in your browser.
A .gltf file often references external .bin and image files. When you upload only the .gltf, those linked files are not included. For self-contained viewing, use a .glb (binary glTF) instead.
GLTF is usually a JSON file that references separate texture and data files, while GLB packs everything into one binary file. GLB is easier to share; GLTF is easier to edit.
No. The GLTF viewer runs entirely in your browser, so there is nothing to download or install.
No. Your .gltf file is loaded and rendered locally inside your browser, so it never leaves your device. This keeps your models private and loading fast.
You can view GLTF files up to 50MB. For very large or high-detail files, close other browser tabs to free up memory for the smoothest performance.
The viewer is for viewing and inspecting only. If you need to change formats, use the Vega3D 3D Converter to convert between STL, OBJ, GLB, GLTF and more.
Yes. Because it runs in the browser, you can open and rotate GLTF models on a phone or tablet using touch gestures, with no app required.
