STL to OBJ Converter

Convert an STL mesh into a Wavefront OBJ file in your browser. OBJ is supported by virtually every 3D application — Blender, Maya, Cinema 4D, Unity, and more — making it the go-to format when you need to take a 3D-print model into a modelling or game engine.

Converting STL to OBJ in practice

STL stores only raw triangles — no colour, no texture, no material. OBJ carries all of that, which is why moving from STL to OBJ is the step you take when a print-ready mesh needs to become an editable, paintable asset. Blender, Maya, Cinema 4D and ZBrush open OBJ natively, where many treat STL as a second-class import.

Convert here when you have a model from a slicer or a download site and want to retexture it, render it, or hand it to a game or animation pipeline. The geometry comes across exactly; you simply gain a container that can hold the UV coordinates and material references STL was never designed to store.

When to convert STL to OBJ

  • Import a printable STL into Blender or Maya for editing
  • Bring a model into a game engine like Unity or Unreal
  • Share geometry with a tool that does not read STL

About the STL and OBJ formats

STL

Stereolithography mesh — the standard format for 3D printing.

OBJ

Wavefront OBJ — a widely supported 3D geometry format.

How it works

How to convert STL to OBJ

  1. Upload or paste a STL link

    Drop a STL file from your device, or paste a public URL pointing to the STL you want to convert.

  2. Confirm OBJ as the output format

    The output is pre-set to OBJ. You can adjust quality or bitrate in the advanced options if you need a smaller file.

  3. Start the conversion

    Click Convert. Our cloud workers fetch the STL, scan it for malware, and run the STL → OBJ pipeline.

  4. Download your OBJ file

    A one-time pre-signed link appears as soon as the OBJ is ready. The file is automatically deleted from our storage 2 hours later.

STL to OBJ — Frequently asked questions

STL files store only geometry — no color, texture, or material data — so the OBJ will contain the mesh shape only. If you need color and materials, convert to 3MF or GLB instead.
