Use this free tool to view your 3D STL (Standard Triangle Language) files online without needing to install any software.
Our tool can load most binary and text based STL files. If you are looking to convert your 2D image files to 3D STL files then we have a 2D to 3D conversion tool here.
Here are 2 simple steps to display your STL file in any web browser.
You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.
First click the "Upload..." button, select your STL file to upload. Select any configuration options. When the STL to STL conversion has completed, you can download your STL file straight away.
We aim to process all STL to STL 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 STL file you submit to us. The resulting STL file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STL to STL 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 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.

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.
