OBJ
Your converted model will appear here.
OBJ · geometry only
OBJ keeps numeric coordinates. Confirm units on import. This export contains geometry only, with no MTL or textures.
A geometry-only OBJ with baked scene transforms and shared vertex positions. Keep the original GLB for its appearance and animation.
REAL CONVERSION EXAMPLE
Keep the car's shape. Leave the paint in GLB.
The colored toy car becomes a static OBJ surface. Its 108,936 triangles remain; the exported file has no UVs, MTL or texture package.

GLB vs OBJ: packaged appearance or editable geometry
OBJ can support material libraries, but this route extracts only the static mesh. That distinction matters when the original GLB has detailed textures or animation.
Source formatGLB
Binary glTF (GLB)
A binary container for a glTF scene. A self-contained GLB can carry geometry, materials, images and animation in one file.
Structure
Scene nodes can position, rotate and scale meshes. The converter bakes static transforms into vertex positions instead of exporting the scene hierarchy.
Color & texture
GLB can store PBR materials and textures. Keep the original GLB if its rendered look matters: the STL and OBJ routes here export geometry only.
Scale & units
glTF uses meters for linear distances. STL export explicitly rescales the bounding box; OBJ export retains the numeric geometry coordinates.
Best suited to
Browser viewing and sharing an asset with appearance. A geometry-only copy is useful when your next tool needs a static mesh.
Output formatOBJ
Wavefront OBJ
A text-based surface description built from vertex coordinates and faces. It is widely used to move meshes between modeling applications.
Structure
Vertices can be shared by faces; polygon faces are possible. This converter reads mesh faces and triangulates them, ignoring line and point primitives.
Color & texture
OBJ can reference an MTL library, UV coordinates and separate texture images. Those are format capabilities; this converter exports geometry without that package.
Scale & units
An OBJ generally does not declare a dependable physical unit. Check import scale and a known measurement in your next application.
Best suited to
Static mesh exchange and shape editing. Use an editor to prepare topology, UVs or materials for your final purpose.
When a geometry-only OBJ is the right handoff
A plain OBJ is useful for changing a silhouette or cleaning a mesh. It needs additional work when the next goal depends on appearance or deformation.
For mesh editing
Open the surface in an editor, inspect normals and disconnected pieces, and retopologize when a triangle-heavy asset is hard to modify.
For rendering or animation
Create UVs, assign materials and build a rig in your editor. If you only want to view the textured asset, keep GLB and use the GLB viewer instead.
From your file to the next step
Select a step to see what happens. Try the actual conversion above when you are ready.
Use a valid self-contained GLB 2.0. External buffers and required Draco or Meshopt compression are not supported.
A static mesh task
This route produces one geometry-only OBJ. It does not package images, UVs, MTL, animation tracks or a skeleton.
Enough memory for a text export
Source limits are 100 MB and 1 million triangles. An OBJ can be larger than its binary GLB source; simplify dense assets before using a low-memory device.
UNDER THE SURFACE
What the GLB to OBJ exporter actually writes
The export is a static geometry handoff. Its text representation is different from a GLB container.
GLBXYZOBJ
01
Read the scene's mesh
Embedded triangle data is loaded, without texture images. Only mesh primitives are included in the conversion.
02
Bake transforms
Static scene positions, rotations and scales are written into vertex coordinates. Animation tracks and the original node hierarchy are omitted.
03
Share positions and write faces
Identical vertex positions are reused by indexed OBJ faces. Numeric coordinates are preserved; UV, material and texture references are not written.
For artists who need the mesh itself
Blender and mesh-editor users
Import the OBJ in Blender or a compatible editor to inspect and reshape the static geometry.
Artists reviewing the geometry
Compare the colored GLB with a clay or wireframe view of the exported OBJ.
Web asset creators
Use the original GLB when textures, materials or animation are part of the final experience.
A small tool that fits your workflow
Convert, check the result and keep control of your original asset.
Your files stay with you
Local files are read and converted on your device. No model upload is needed; public sample files are downloaded only when you choose them.
GLBOBJSTL
Free, without an account
Convert an existing mesh without signing in or spending generation credits.
See what changed
Rotate the source and exported geometry before downloading. The format table tells you exactly what is kept or omitted.
An explicit next step
Set STL dimensions, cancel a conversion or inspect the exported mesh. Errors have a visible message and you can select another file.
AFTER THE DOWNLOAD
An OBJ is a starting mesh for your editor
Use the exported geometry for shape work. Keep the GLB when you still need its rendered appearance.
OBJ is a static mesh handoff and this exporter omits animation tracks and rigs.
What to do
Keep the GLB or use an animation-capable format in your editor. Do not expect changing an extension to preserve a rig.
The imported mesh is sideways
The destination's forward and up-axis conventions differ.
What to do
Review the OBJ import Forward Axis and Up Axis options. Compare orientation with the source before saving.
The OBJ is larger than the GLB
Text coordinates and face records can take more bytes than the GLB's binary geometry.
What to do
Judge the result by the exported mesh, not by file size alone. Use an editor if you need polygon reduction.
The GLB cannot be converted
Required compression, external geometry or a malformed container may be unsupported.
What to do
Re-export a self-contained uncompressed GLB 2.0, then choose the new file.
Conversion questions
Does GLB to OBJ preserve textures?
This exporter produces geometry only. It does not write UV coordinates, an MTL or image files. Keep the original GLB when appearance matters.
Can it convert Draco or Meshopt-compressed GLB files?
Not in this exporter. Export an uncompressed, self-contained GLB first. The tool reports unsupported compressed geometry instead of silently producing an incomplete model.
Will animations and rigs work in the OBJ?
No. The OBJ is a static mesh. Scene and instance transforms are baked into its vertices; animation tracks and skeleton data are not exported.
