Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your binary GLB 3D files into human-readable GLTF format. This tool is essential for developers and designers who need to access and edit individual 3D assets.
GLB is a self-contained binary file that packs geometry, textures, and animations into a single package. Converting to GLTF (GL Transmission Format) unpacks these elements, creating a JSON-based file that references external textures and binary buffers, making the structure easier to inspect and modify manually.
The conversion is lossless. Since you are simply changing the container format, all 3D data and texture quality remain identical to the original.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
