Features
EverythingYou Need
Professional-grade 3D model compression and optimization tools that run entirely in your browser. No servers, no uploads, no compromises on quality.
Draco Mesh Compression
Leverage Google's industry-standard Draco algorithm to achieve up to 90% file size reduction while preserving geometric accuracy. Fully compatible with all major 3D engines and frameworks.
Smart Texture Optimization
Automatically convert and resize textures to modern formats like WebP and AVIF. Fine-tune compression quality from 1-100% to find the perfect balance between visual fidelity and file size.
Interactive Real-time Preview
Compare your original and compressed models side-by-side with our built-in 3D viewer. Inspect every detail before exporting to ensure quality meets your standards.
100% Private & Secure
Your intellectual property stays yours. All processing happens locally on your device - no uploads, no cloud storage, no data collection. Perfect for confidential projects and NDA-protected assets.
Powerful Batch Processing
Drop entire folders or multiple files at once. Process dozens of 3D assets simultaneously and download them all when ready. Streamline your entire asset pipeline in one session.
Simple Process
Howit Works
Optimize your 3D assets in four simple steps. No technical expertise required - just drag, configure, preview, and download.
1
Drop Your Files
Drag and drop your GLB or GLTF files directly into the browser. No upload needed - everything stays on your device.
2
Configure Settings

Use Cases
BuiltforModern 3DWorkflows
Whether you are building for web browsers, e-commerce platforms, or immersive AR/VR experiences - optimized 3D assets mean faster load times, better performance, and happier users.
Web & WebGL Applications
Dramatically reduce loading times for Three.js, React Three Fiber, and Babylon.js projects. Optimized GLB files mean faster initial renders and smoother user experiences on any device.
E-commerce & Product Visualization
Convert high-fidelity product scans into web-ready assets. Lighter 3D models lead to faster page loads, lower bounce rates, and higher conversion rates for your online store.
AR/VR & Gaming
Maintain high frame rates and reduce memory usage in immersive experiences. Optimized meshes and textures ensure smooth performance across mobile AR, VR headsets, and browser-based games.

FAQ
Answers,withoutthe fluff
Quick clarifications so you can compress with confidence.
Do you upload my files to any server?
Absolutely not. 3D Compressor runs 100% locally in your browser using WebAssembly technology. Your files never leave your device - there is no server processing, no cloud storage, and no data collection whatsoever. This makes it perfect for confidential projects and NDA-protected work.
Which 3D file formats are supported?
We support GLB (binary glTF) and GLTF formats - the industry standard for web-based 3D content. GLB is recommended for web deployment as it packages everything into a single file. If you have FBX or OBJ files, convert them to GLB using Blender first.
Do I need to create an account or install software?
No account required, no software to install. Simply open 3D Compressor in any modern browser, drag and drop your model, and start compressing immediately. Completely free with unlimited compressions.
Will Draco compression work with my 3D engine?
Yes! Draco-compressed GLB files are supported by all major 3D frameworks including Three.js (with DRACOLoader), React Three Fiber, Babylon.js, Unity (with glTFast), Unreal Engine, and PlayCanvas. The format is an official Khronos standard.
How much file size reduction can I expect?
Typical compressions achieve 70-90% reduction depending on your model complexity and settings. A 24MB model can often be reduced to under 4MB while maintaining excellent visual quality. Results vary based on mesh density, texture resolution, and compression parameters.
How do I maintain visual quality while compressing?
You have full control over the compression trade-offs. Adjust texture format (WebP, AVIF, JPEG), resolution scaling, Draco quantization levels, and mesh simplification ratios. Our real-time preview lets you compare before and after side-by-side, ensuring quality meets your standards before export.
Can I process multiple files at once?
Yes! Our batch processing feature lets you drag and drop entire folders or select multiple files simultaneously. Process dozens of assets in parallel and download them all when ready - perfect for optimizing entire game levels or product catalogs.
Is there an API for automated workflows?
Enterprise API support is available for teams requiring integration into CI/CD pipelines, automated asset processing, or high-volume optimization. Contact us to discuss your workflow needs and we will recommend the right solution.
