Convert Your 3D Mesh/Model STEP Files to OBJ

to

Our free and fast tool will convert most 3D mesh or STEP (STEP-File) model files to a standard OBJ (Wavefront) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing.

To convert your STEP file click the Upload button above and select the file to convert. Once selected, the file will be converted to a OBJ file and will ready for download shortly afterwards. For more information about the STEP to OBJ conversion process see the conversion information section below for more information.

FAQ

How can I convert my STEP file to OBJ?

First click the "Upload..." button, select your STEP file to upload. Select any configuration options. When the STEP to OBJ conversion has completed, you can download your OBJ file straight away.

How long does it take to convert my STEP to OBJ?

We aim to process all STEP to OBJ conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the STEP to OBJ conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features being added every week.

Is it safe to convert my STEP to OBJ on ImageToStl.com?

Yes, of course! We do not store the STEP file you submit to us. The resulting OBJ file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert STEP to OBJ on Windows, Linux, Android, iOS or Mac OS?

Yes! Our STEP to OBJ tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

File format information for STEP to OBJ

Extension: STEP

Full Name: STEP-File

Type: 3D Model

Mime Type: application/octet-stream

Format: Binary

Description

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STEP files are text-based formatted files containing one instance per line.

Although STEP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.

STEP Notes

STEP files when imported will be converted to 3D geometry comprising vertices and faces. If the STEP file contains color information this will be converted where possible.

Supported Features

  • Mesh geometry
  • Mesh colors

Extension: OBJ

Full Name: Wavefront

Type: 3D Model

Mime Type: text/plain

Format: Text

Description

The OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.

As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.

OBJ Notes

Our tool does not currently support saving material or color information for OBJ files.

Supported Features

  • Mesh geometry

Unsupported Features

  • Textures
  • Material colors
