Check geometry before handoff
Review the silhouette, proportions, and visible surfaces before the model enters a larger production workflow.
Free 3D Tool
GLB Viewer
Open a GLB file online and inspect your 3D model in the browser. Rotate, zoom, and review the model before you export it, share it, or continue texturing.

About this tool
Open and inspect GLB models without installing 3D software
GLB is the binary form of glTF. It is commonly used for web 3D, real-time previews, game assets, AR handoffs, and generated model exports because geometry and supported materials can travel together in one file.
Use this GLB viewer when you need a quick visual check before opening Blender or sending a model to another person. The viewer reads the file locally, frames the model for you, and gives you a simple orbit and zoom preview.
02
Preview embedded materials
GLB files with embedded textures and materials can be inspected in the same browser preview.
03
Keep a fast local review step
Open a file without creating an account, spending credits, or moving the model through a server upload.
Built for real 3D workflows
Who uses GLB Viewer?
3D artists
Check a generated or exported GLB before opening a full DCC application.
Game and web teams
Review a real-time asset's shape and surface direction before it moves into an engine or website.
Product and client review
Give a teammate a quick visual inspection path when they do not have 3D software installed.
How it works
Use GLB Viewer in three steps
01
Choose a GLB file
Select a local GLB file from your computer. The file is used only in this browser session.
02
Inspect the model
Rotate, zoom, and reset the view to check the model from different angles.
03
Continue your workflow
When the model needs a different surface, continue with Texture Generator in Fastin3D.

Need textures for your model?
Open Fastin3D Texture Generator to explore a new material direction for an existing 3D model.

FAQ
Questions about GLB Viewer
What is a GLB file?
GLB is a binary form of glTF that can package a 3D scene, materials, and supported textures into one file.
Does the GLB Viewer upload my file?
No. The preview is created in your browser session. The file is not sent to Fastin3D for this free viewer.
Can I rotate and zoom the model?
Yes. Drag to orbit around the model, use the wheel or trackpad to zoom, and use Reset to return to the starting view.
Why does a GLB file sometimes look different?
A browser viewer may render lighting, materials, animations, or unsupported extensions differently from Blender or another 3D application.
Does the GLB Viewer play animations?
The current preview is focused on inspecting the model's geometry and materials from different angles. It does not provide a full animation timeline.
What should I do if the model appears blank?
Check that the GLB contains embedded model data and textures, then run it through GLB Validator. Very large or damaged files may also fail to render in a browser.
