Convert Your 3D Mesh/Model STL Files to SKP

Our free and fast tool will convert most 3D mesh or STL (Standard Triangle Language) 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 STL files; up to 25 files at a time can be converted.

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

How to Convert your STL to SKP Online?

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

Upload a STL

Click the "Upload a STL File" button and select a STL 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 STL file to SKP?

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

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

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

Yes, of course! We do not store the STL 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 STL to SKP on Windows, Linux, Android, iOS or Mac OS?

Yes! Our STL 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 STL 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.

What STL formats can I convert from?

You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.

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

Yes! Our STL tool supports full batch conversions. You can upload up to 25 and STL 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.

Description

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format, namely SolidView and VisCAM, whose formats included limited 15-bit color information for each mesh face, which is often ignored by most modern 3D software. The STL format can be either text or binary; our tools will support both formats.

STL Notes

Standard STL files do not contain material or color information, so this cannot be imported. There are, however, two formats (VisCAM and SolidView) that attempt to add color information to the STL file format. If our tool detects this additional color information, it will attempt to import this information.

Supported Features

  • Mesh geometry
  • Face colors via the VisCAM and SolidView formats
  • Binary and text versions are supported

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

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

Supported Features

  • Polygon mesh
  • Face colors

How does it work?

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

Step 1: Read the Source STL File

In its simplest form, an STL file can be either a plain text or binary 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 STL file format, please see this great article that goes into a lot of detail explaining the STL format.

Step 2: Process File Data

With the STL 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 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 it to the SKP format.
