Turn a .glb into a plain-text .obj that every 3D application on earth can open. It runs in this tab, so nothing is uploaded, and the UV coordinates survive the trip even though the materials do not.
Three steps, one page, no account. The whole conversion is a local operation — the slowest part is you finding the file.
Drag the file onto the box above. It is read straight off your disk with the browser's File API — no upload, and no progress bar to a server.
The file is parsed, every mesh is baked into world space, and the result is written out in the target format. Your CPU does the work, so a client's unreleased model never leaves the room.
Save the converted file and open it wherever you were headed. Nothing is watermarked and nothing expires.
They solve different problems, which is exactly why one direction of this conversion costs you something and the other does not.
GLB is the binary flavour of glTF — one file carrying geometry, UV coordinates, materials, textures and a scene graph together. It is what the web, Blender, Unity, Unreal and Three.js all read natively, and it is what this site's generator hands you.
OBJ is a plain-text mesh format from the late eighties that every 3D application on earth can read. Geometry, normals and UV coordinates live in the .obj itself; materials live in a separate .mtl file beside it.
Every conversion is a trade. Any tool that tells you otherwise is lying to you, so here is the exact ledger before you commit.
Need the texture with it? Keep the original GLB alongside the OBJ — it already holds the images, and any tool that reads GLB will read them. The other converters are all free too.
OBJ is the lowest common denominator of 3D interchange. Reach for it when the tool at the other end is older than glTF, or when you want geometry plus UVs in a format you can read in a text editor.
Expect a larger file and an untextured mesh: plain-text coordinates are several times the size of the same binary geometry, and the images stay behind in the GLB. Check the model in the viewer before you commit to the conversion.
You do not have to go back to the home page. Type a prompt or drop an image, and take the .glb — free, anonymous, no watermark.
OBJ keeps materials in a companion .mtl file, and this converter writes only the .obj. The geometry, normals and UV coordinates are all there, so you can reapply the texture from the original GLB in whatever tool you are importing into.
GLB, almost always. Unity, Unreal and Godot all read it natively, it carries the texture in the same file, and it is binary rather than text. OBJ is worth converting to when the destination cannot read glTF at all.
Same converter, same rules: free, in your browser, no signup.
3D AI Studio generates the .glb too — free, anonymous, no watermark.
No signup, no upload, no watermark — and the converter does not care how big the file is.
