Convert Your 3D Mesh/Model OBJ Files to OFF

to

Our free and fast tool will convert most 3D mesh or OBJ (Wavefront) model files to a standard OFF (Object File Format) 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 OBJ file click the Upload button above and select the file to convert. Once selected, the file will be converted to a OFF file and will ready for download shortly afterwards. For more information about the OBJ to OFF conversion process see the conversion information section below for more information.

Upload a OBJ

Click the "Upload a OBJ File" button and select a OBJ to upload. The maximum file size is 100MB.

Download your OFF

Click the download link once completed to receive your OFF file.

How can I convert my OBJ file to OFF?

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

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

We aim to process all OBJ to OFF 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 OBJ to OFF conversion?

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

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

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

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

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

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our OBJ conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

File format information for OBJ to OFF

Extension	OBJ
Full Name	Wavefront
Type	3D Model
Mime Type	text/plain
Format	Text
Open With	MeshLab, CAD Assistant, DAZ Studio

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

Currently our tool does not support importing materials or color information from your OBJ file.

Open With	MeshLab, CAD Assistant

Description

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shape, edge information and also has support for including color information. As the format is text based the files can become rather large with no built-in compression options available.

OFF Notes

OFF files support per face color information. If your uploaded model contains color information our tool will attempt to save this in the OFF file at the end of the conversion process.
