Yes! Our 3D model compression tool is completely free with no limitations. You can compress GLB and GLTF files unlimited times, enjoying up to 95% compression ratio, and no account registration is required.

No. All compression processes are performed locally in your browser, and your model files are not uploaded to our servers. This ensures your data privacy and security.

Our compression algorithm is designed to minimize file size while preserving visual quality as much as possible. While some advanced compression settings may have minor visual impacts on the model, under default settings, most models maintain nearly identical visual quality.

Currently, we support 3D model files in GLB and GLTF formats. These formats are industry standards for Web 3D content and are widely used in AR/VR, gaming, e-commerce, and online visualization.

Since compression happens in the browser, file size is mainly limited by your device's memory. Typically, model files under 100MB can be processed smoothly. For particularly large models, we recommend first trying other tools for initial optimization.

Compression time depends on the complexity of the model and your device performance. Typically, models of a few MB can be compressed in seconds, while larger models may take 1-2 minutes. The entire process takes place in the browser, eliminating waiting for uploads and downloads.

Compressed models are fully compatible with all platforms and engines that support GLB/GLTF formats, including Three.js, Babylon.js, Unity, Unreal Engine, AR/VR platforms, and more. Our compression follows standard specifications to ensure maximum compatibility.

We offer various compression options, including geometry compression (reducing vertex count), texture compression (lowering image resolution and quality), animation compression, material merging, and more. You can adjust these parameters according to your needs to find the optimal balance between file size and visual quality.

Currently, we focus on providing the best online compression experience. If you need to process a large number of models in batch or require API integration, please contact our support team, and we can provide customized solutions based on your specific needs.
