Use this free tool to view your 3D STL (Standard Triangle Language) files online without needing to install any software. Our STL viewer tool will generate a real-time 3D preview of your STL file with Pan and Zoom controls allowing you to see your 3D model from any angle.
Our STL viewing tool can load most STL 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.
Here are 2 simple steps to display your STL file in any web browser.
First, click the "Upload..." button and select the STL file you wish to view. Once your STL file has been received it will be displayed in your browser.
We aim to process all STL file viewing requests as quickly as possible, this usually takes around 5 seconds but can be more for larger or more complex files so please be patient.
We aim to create the most accurate rendition of your STL file 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 STL file you submit. The generated preview file within your browser is deleted after 15 minutes,
Yes! Our STL file viewer will run on any system with a modern web browser. No specialist software is needed to use our file viewing tools.
You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.
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.
