glTF to OBJ Converter

Turn glTF files into OBJ without installing anything. The target format on this page is already set to OBJ, so a single file or a whole folder is one press of Convert away.

glTF and OBJ: what actually changes

glTF is "the JPEG of 3D" — a JSON scene with PBR materials, ready to drop into a browser. OBJ is plain-text geometry with an .mtl sidecar for materials — universal, and very old.

Meshes, normals and UV coordinates are translated between the two scene descriptions rather than re-tessellated, so the geometry you get out is the geometry you put in. The OBJ you get back keeps vertices, normals, UVs and material references, and gives up animation, rigs and scene hierarchy. Check materials and texture paths afterwards — that is where glTF and OBJ disagree most.

How it goes3 steps

  1. Add your glTF files
    Drop them onto the box above or click Select File. Add as many .gltf files as you like — the whole batch converts in one go, and duplicates are ignored.
  2. Confirm OBJ as the output
    OBJ is already selected as the target format on this page. Tweak the options if you need something other than a straight OBJ file.
  3. Download your OBJ
    Hit Convert and grab the finished OBJ files individually or as a single ZIP. Everything is deleted from the server once you have them.
