Convert Your 3D Mesh/Model OBJ Files to SKP

Our free and fast tool will convert most 3D mesh or OBJ (Wavefront) model files to a standard SKP (SketchUp) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple OBJ files, up to 25 files at a time can be converted.

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 SKP file and will ready for download shortly afterwards. For more information about the OBJ to SKP conversion process see the conversion information section below for more information.

How to Convert your OBJ to SKP Online?

Here are 2 simple steps to convert your OBJ to SKP.

Upload a OBJ

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

Download your SKP

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

Frequently Asked Questions

How can I convert my OBJ file to SKP?

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

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

We aim to process all OBJ to SKP 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 SKP 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 SKP on ImageToStl.com?

Yes, of course! We do not store the OBJ file you submit to us. The resulting SKP file, once created is deleted 15 minutes after upload and the download link will expire after this time.

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

Yes! Our OBJ to SKP 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.

My OBJ file contains materials and textures, how do I upload these?

If your OBJ file has separate material (MTL) and texture (PNG, JPG etc.) files, you can drag and drop these onto the upload tool along with the main OBJ file. Our tool will intelligently detect which of these additional files belong with the OBJ file. Alternatively, you can place these additional files, along with the OBJ file within a ZIP or other compressed archive file and upload that.

I have several OBJ files, can I batch convert my OBJ to SKP?

Yes! Our OBJ tool supports full batch conversions. You can upload up to 25 OBJ files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the SKP files individually or download them all in a single ZIP file.

How does it work?

Converting from the OBJ file format to SKP can be a complex process and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your OBJ file to a valid SKP 3D model. Lets start with the conversion process, which involves the following steps:

Step 1: Read the Source OBJ File

In its simplest form, an OBJ file is a plain text file containing human readable 3D data such as vertices, faces, normals and more. When combined, these make up the 3D model you see on your screen.

When our tool reads in this 3D data all we are interested in are the vertices, faces and normals as this is the only data that can be accurately converted into the final SKP file.

The OBJ file can contain other data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an SKP file, which does not support materials and textures, we will be ignoring this data if it is present in the OBJ file.

Step 2: Process File Data

With the OBJ file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model ready for exporting to the SKP format.

Step 3: Saving to the SKP Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert this to the SKP format.

File format information for OBJ to SKP

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

If your OBJ file is uploaded with an accompanying MTL and texture files, these will be applied to the conversion process.

Description

The SKP 3D file format is the native file format used by SketchUp. The SketchUp application which was released back in 2000 is still going strong today, allows users to create detailed 3D graphics models.

SketchUp is popular amongst architectural designers, games developers and other professionals and hobbyist users. The SKP format can be opened with the SketchUp application.

SKP Notes

Any model converted to the SKP format will be stored in a triangulated mesh format.

Supported Features

  • Polygon mesh
  • Face colors
