Our free and fast tool will convert most 3D mesh or PTX (Point Cloud) model files to a standard STL (Standard Triangle Language) 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 PTX files; up to 25 files at a time can be converted.
To convert your PTX file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a STL file and will be ready for download shortly afterwards. For more information about the PTX to STL conversion process, see the conversion information section below.
Here are two simple steps to convert your PTX to STL.
First click the "Upload..." button, select your PTX file to upload. Select any configuration options. When the PTX to STL conversion has completed, you can download your STL file straight away.
We aim to process all PTX 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 PTX file you submit to us. The resulting STL file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our PTX 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 PTX 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.
Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.
Yes! Our PTX tool supports full batch conversions. You can upload up to 25 and PTX files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the STL files individually or download them all in a single ZIP file.

The PTX is a 3D file format used for representing 3D Point Clouds. The format contains only positional information (X, Y, and Z coordinates) for the individual points. The format is often used for digital elevation modeling of terrain for later processing in 3D modeling applications.
As the format only contains positional information, a common task is to convert this into a fully surfaced 3D model using methods such as Alpha Shapes or Delaunay Triangulation. The format can also be viewed without further processing in its raw format.
The PTX file format was designed to store vertex information only to allow the construction of simple Point Cloud models.

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.
The standard STL file format does not support colored faces, vertices, or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default, which is perfect for 3D printing.
The tool also has the option to save the file to one of the non-standard formats that support colored faces, such as VisCAM and SolidView which is perfect if you want to further process the STL in software that supports these formats.
