View 3D ITSP Files Online

Use this free tool to view your 3D ITSP (ImageToSTL Project) files online without needing to install any software. Our ITSP viewer tool will generate a real-time 3D preview of your ITSP file with Pan and Zoom controls, allowing you to see your 3D model from any angle.

Our ITSP viewing tool can load most ITSP files, and we are working on improvements all the time to improve compatibility with all file formats. If you are looking to convert your 2D image files to 3D files, such as STL, then we have a 2D to 3D conversion tool here.

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.
