Free 3D Model Thumbnail Generator
Load a 3D model, position the camera, choose a background and resolution, then export a clean PNG thumbnail — all without leaving your browser.
How It Works
Load your model
Drop a GLB, OBJ, STL, FBX, or PLY file. It renders immediately in a WebGL viewport.
Frame the shot
Drag to rotate, scroll to zoom, and right-drag to pan until you find the perfect angle.
Capture & download
Choose your resolution and background, then capture a square PNG thumbnail at up to 2048 × 2048.
Why Use This Tool
Fully private
WebGL renders locally in your browser. No cloud rendering, no server uploads.
Instant rendering
Hardware-accelerated WebGL renders your model at full quality in real time.
Transparent PNG support
Export with a transparent background for use on any website or in any design tool.
Frequently Asked Questions
What is this tool used for?
It generates a PNG screenshot of a 3D model for use as a product thumbnail, asset preview, portfolio image, or marketplace listing. You position the camera interactively then capture.
How do I position the model before capturing?
Use left-click drag to rotate, scroll wheel to zoom, and right-click drag to pan — the same controls as the Online 3D Viewer. Once you have the angle you want, click "Capture" to export the PNG.
What does the transparent background do?
Transparent background exports the thumbnail as a PNG with an alpha channel, so the model appears without any background when placed in designs, presentations, or HTML pages.
What resolution should I choose?
512 px is fine for small thumbnails and icon-sized previews. 1024 px is good for most product pages and marketplace listings. 2048 px is for high-DPI displays and print use.
Does my file get uploaded?
No. The 3D model is loaded and rendered entirely in your browser using Three.js and WebGL. The PNG screenshot is generated from the browser canvas. Nothing is sent to a server.
