GLB to OBJ converter

Turn a GLB into an OBJ with its materials and textures — a ZIP with the .obj, the .mtl and the texture images, ready for Blender, Maya, 3ds Max and renderers.

  • Free account · 5 conversions a day
  • Private · deleted after 29 days
  • GLB up to 50 MB

What changes

What changes when a GLB becomes an OBJ

OBJ is older and simpler than glTF. This is how your model is carried over.

  • One file becomes a folder

    A GLB packs everything into one file. An OBJ keeps the mesh in the .obj, the materials in an .mtl and each texture as its own image, so you get a ZIP — unzip it and keep the files together.

  • Textures as PNG

    glTF often stores textures as WebP, which OBJ apps don't read. Every texture is saved again as PNG, pixel for pixel.

  • PBR, the OBJ way

    MTL is older than PBR. The colour texture comes through everywhere; metal, roughness and normal maps have no agreed place in MTL, so apps read them differently. For full PBR, keep the GLB or use FBX.

  • Same mesh, Y-up

    Triangles, UVs and normals are kept, Y-up like the GLB. Faces the GLB shows from both sides get a second, turned copy, because OBJ has no double-sided setting.

How it works

GLB to OBJ in three steps

  1. 1

    Drop your GLB

    Up to 50 MB. It opens in 3D right away, before anything is uploaded.

  2. 2

    Sign in free

    OBJ with textures is made on our servers, so it needs a free Wandy3D account.

  3. 3

    Download the ZIP

    The conversion takes a minute or two, and the ZIP downloads by itself.

Your file stays yours

  • GLB, STL, OBJ or 3MF, up to 50 MB and 2 million triangles.
  • STL, 3MF and GLB (and OBJ from an STL or 3MF) are made in your browser — the file never leaves your device. For OBJ from a GLB, USDZ and FBX it is stored privately and deleted after 29 days.
  • Never used to train AI, never shown to anyone, never added to the community.
  • Delete an upload any time with one click — or together with your account.

Yes, with a free Wandy3D account: 5 server conversions a day, up to 100 a day with a plan. STL, 3MF and GLB conversions run in your browser with no account at all.

Writing the OBJ, its MTL and the textures takes our export tools, which run on our servers. The account keeps your upload private to you and lets you delete it.

Unzip it and import the .obj — the .mtl next to it points at the textures folder. Keep the three together if you move them. The colour texture shows up in every app; other PBR maps depend on the app.

OBJ can't store bones or animation, so you get the model in its rest pose. To keep the rig and its clips, convert to FBX instead.

It's uploaded privately, used only for your conversion, kept for 29 days and then deleted automatically — or at once when you delete it. It's never used to train AI. Details: Privacy Policy.

Yes, and without an account: an STL or 3MF has no materials to keep, so its OBJ is made right in your browser — see STL to OBJ.
