Our free and fast tool will convert your 3D ITSP (ImageToSTL Project) model files to a standard SKP (SketchUp) file that can then be edited further in most popular 3D editing packages or 3D printed without any further processing. Our conversion tool can also batch convert multiple ITSP files; up to 200 files at a time can be converted.
To convert your ITSP 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 ITSP to SKP conversion process, see the conversion information section below.

The ITSP file format is a 3D file format used to store simple 2D image data in a way that allows it to be represented in 3D space through the use of extrusion. The format is the native format of the ImageToSTL 3D Model Designer application and was devised as a means to allow users with basic knowledge of 2D bitmap drawing and editing software to create complex 3D objects suitable for 3D printing.
An ITSP file consists of a main data file containing the position, rotation, and scale of a 2D object that is to be projected into 3D space. The objects are arranged into layers, with each layer being assigned a depth, allowing 3D objects to be created. Along with the data file are PNG image files of each element, and all these files are packed into a ZIP container with the ITSP file extension.

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.
Any model converted to the SKP format will be stored in a triangulated mesh format.
Converting from the ITSP 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 ITSP file to a valid SKP 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an ITSP 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 ITSP file format, please see this great article that goes into a lot of detail explaining the ITSP format.
With the ITSP 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.
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.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full ITSP file compatibility. Our bespoke file conversion tools offer full ITSP file compatibility and have been developed in-house by a team of developers, some of whom have over 30 years of experience working with 3D graphics file formats, meaning our tools will convert your ITSP file quickly and accurately with maximum compatibility.
Yes! Our ITSP tool supports full batch conversions. You can upload up to 200 ITSP 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.
First click the "Upload..." button, and select your ITSP file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the ITSP to SKP conversion has completed, you can download your SKP file straight away.
We aim to process all ITSP 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.
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.
Yes, of course! We do not store the ITSP file you submit to us. The resulting SKP file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
No. All our conversion tools process your ITSP file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted SKP file quickly.
Yes! Our ITSP 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.
Yes. Although you can use an Ad Blocker, if you like our ITSP conversion tool please consider white-listing our website. When an Ad Blocker is enabled there are some conversion limits and some settings may not be available when using our tools. Processing/conversion and download times will also be longer.
Yes. When you have converted your ITSP to SKP, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
