Convert Your 3D Mesh/Model SKP Files to OFF

Our free and fast tool will convert most 3D mesh or SKP (SketchUp) 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. Our conversion tool can also batch convert multiple SKP files; up to 25 files at a time can be converted.

To convert your SKP 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 be ready for download shortly afterwards. For more information about the SKP to OFF conversion process, see the conversion information section below.

How to Convert your SKP to OFF Online?

Here are two simple steps to convert your SKP to OFF.

Upload a SKP

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

Download your OFF

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

Frequently Asked Questions

How can I convert my SKP file to OFF?

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

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

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

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

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

Yes! Our SKP 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 SKP 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.

I have several SKP files; can I batch convert my SKP to OFF?

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

Description

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

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

SKP Notes

Our tool will export only polygon mesh data along with color information. Curved surfaces and textures are not supported and will be ignored.

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 the storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shapes, and edge information, and it 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.

Supported Features

  • Mesh geometry
  • Face colors

How does it work?

Converting from the SKP file format to OFF 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 SKP file to a valid OFF 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source SKP File

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

For more information regarding the SKP file format, please see this great article that goes into a lot of detail explaining the SKP format.

Step 2: Process File Data

With the SKP 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 for exporting to the OFF format.

Step 3: Saving to the OFF 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 it to the OFF format.
