Question 1

What is GLBKit?

Accepted Answer

GLBKit is a browser-based toolkit for viewing, inspecting, analyzing, and working with 3D model files including GLB, glTF, OBJ, FBX, STL, PLY, and OFF. It helps developers, designers, 3D artists, and other users work with 3D assets directly in their browser.

Question 2

What can I do with GLBKit?

Accepted Answer

GLBKit provides browser-based tools for viewing, inspecting, analyzing, capturing screenshots, and converting supported 3D model formats. You can preview model structure, geometry, materials, textures, animations, and other asset details depending on the tool you use.

Question 3

Which 3D file formats does GLBKit support?

Accepted Answer

GLBKit supports common 3D formats including GLB, glTF, OBJ, FBX, STL, PLY, 3MF and OFF, and the viewers additionally open USD, DAE, X3D, VRML, VRM, STEP, PCD, LAS and LAZ files. Support varies by tool, so check the supported formats shown on each tool page before selecting a model.

Question 4

Can I open GLB files online with GLBKit?

Accepted Answer

Yes. GLB files can be opened directly in supported GLBKit browser tools. You can preview and inspect the 3D model without needing to install traditional desktop 3D software.

Question 5

Can I open glTF files online with GLBKit?

Accepted Answer

Yes. GLBKit supports glTF workflows where the required external resources such as BIN files and textures are provided when needed. You can use supported browser-based tools to view and inspect glTF scenes online.

Question 6

Can I view OBJ, STL, PLY, and FBX files online?

Accepted Answer

Yes. GLBKit provides browser-based tools for supported OBJ, STL, PLY, and FBX workflows. You can load compatible models and inspect them directly in your browser without installing dedicated desktop software.

Question 7

Is GLBKit free to use?

Accepted Answer

Yes. GLBKit tools are free to use and can be opened directly in your browser without creating an account. GLBKit continues to expand its tools and features for modern 3D workflows.

Question 8

Do I need to create an account to use GLBKit?

Accepted Answer

No. You can use GLBKit tools without creating an account. Open the relevant tool, select your supported 3D model, and start viewing, inspecting, or working with the asset directly in your browser.

Question 9

Which browsers does GLBKit support?

Accepted Answer

GLBKit works best in modern browsers that support current web technologies and WebGL, including Google Chrome, Microsoft Edge, Firefox, Brave, and Safari. For the best compatibility and performance, we recommend using the latest version of your preferred browser.

Question 10

Can I use GLBKit for WebGL and Three.js projects?

Accepted Answer

Yes. GLBKit is useful for developers working with WebGL, Three.js, React Three Fiber, Babylon.js, and other modern 3D web technologies. Its tools can help you inspect and prepare 3D assets before using them in web applications.

Question 11

Who is GLBKit built for?

Accepted Answer

GLBKit is built for WebGL developers, Three.js and React Three Fiber users, 3D artists, designers, technical artists, product teams, and anyone who works with modern 3D model assets. It is designed to make common 3D asset workflows easier directly in the browser.

Question 12

Can I take screenshots from 3D models in the browser?

Accepted Answer

Yes. GLBKit's screenshot tool renders your model with WebGL and lets you capture high-resolution images as PNG or JPEG. PNG supports transparent backgrounds; JPEG is suitable for solid backgrounds. You can choose HD (1280x720), Full HD (1920x1080), or 4K (3840x2160) resolution.

Question 13

What does the 3D model analyzer report?

Accepted Answer

The analyzer reports geometry (vertices, triangles, indices), rendering statistics such as mesh and primitive counts, materials (count and types), textures (dimensions and estimated memory), memory estimates (geometry, textures, total), object counts, animation clips and durations, and model bounds (dimensions and bounding sphere).

Question 14

Does the analyzer modify my 3D model?

Accepted Answer

No. The analyzer only inspects your model. It reads geometry, materials, textures, and scene data without modifying the file. Your original model is never changed.

Question 15

What is the difference between GLB and glTF?

Accepted Answer

GLB is the binary form of glTF: a single file containing geometry, textures, and materials. glTF is the JSON form: a .gltf file plus separate .bin and texture files. GLB is more convenient for web delivery since it is self-contained; glTF gives you access to individual assets for editing.

Question 16

Can I open files from ZIP packages?

Accepted Answer

Yes. If a model has external dependencies (such as glTF with separate .bin and texture files, or OBJ with .mtl), package the model and all its companion files into a ZIP file and select that. GLBKit will read the contents in the browser.

Question 17

What should I do if my model doesn't load?

Accepted Answer

First, check whether your file format is supported. If the model uses external files (common with glTF), package everything in a ZIP. If the model still doesn't appear, it may be corrupted or use unsupported extensions. Try opening it in another tool to verify the file is valid.

Question 18

Are there file size limits?

Accepted Answer

There is no hard file size limit, but very large models (100MB+) may take longer to load and may impact browser performance. If you are working with large CAD or scan data, consider converting to a more compact format first.

Question 19

How do I convert between 3D formats?

Accepted Answer

Use the format converter. Select your model, choose the output format you need, and download the converted file. The converter reads GLB, glTF, OBJ, FBX, STL, PLY, 3MF and OFF files plus ZIP packages, and exports to GLB, glTF, OBJ, FBX, STL, PLY, 3MF and OFF. Not every source-to-target pair is offered, so the available output formats depend on the source format you select.

Question 20

Can I use GLBKit offline?

Accepted Answer

GLBKit is a web application that requires an internet connection for the initial page load. After the page loads, your model files are processed in your browser, so most tools do not need further network requests while you work.

Question 21

Are my 3D files uploaded to a server?

Accepted Answer

No. GLBKit has no server-side model processing. The file you select is read and processed locally in your browser, and any converted file, screenshot, or thumbnail is produced on your device for you to save. See our Privacy Policy for details on what is and is not transmitted.

Question 22

Does GLBKit store or retain my files?

Accepted Answer

No. GLBKit does not upload, store, or retain your 3D models, screenshots, or converted files. They stay on your device for that session, and the tools do not keep a copy after you close or reload the page. Save any result you want to keep.

Question 23

How can I report a bug or request a feature?

Accepted Answer

Email contact@glbkit.com with the tool name, the 3D model format if relevant, your browser and version, a clear description of the issue, the result you expected, and a screenshot if you have one. See the Contact page for details.
