Online 3D Model Viewer & Optimizer

View, inspect, and optimize 3D files directly in your browser. Support for GLB, GLTF, FBX, and OBJ formats.

Reduce file size by up to 80% using our smart mesh decimation tool. Perfect for optimizing assets for Three.js, Unity, or AR web experiences.

Polygon Reduction

High-poly models kill web performance. Our tool intelligently merges vertices and simplifies geometry to reduce the triangle count without ruining the visual shape.

Format Converter

Convert heavy FBX or OBJ files into modern, web-ready GLB (binary glTF) format. GLB compresses textures and geometry into a single file.

STL Export

Need to 3D print a game asset? Convert your model to STL format instantly. This strips textures but preserves the geometry needed for slicer software.

FAQ

What is the best format for the web?

GLB (glTF Binary) is the industry standard for the web. It supports compression, embedded textures, and is natively supported by Three.js and Babylon.js.

Is my model uploaded?

No. All rendering and optimization happen locally in your browser using WebGL. Your proprietary 3D assets never leave your computer.
