Our free and fast tool will convert most 3D mesh or STP (STEP-File) model files to a standard PLY (Stanford Triangle Format) 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 STP files, up to 25 files at a time can be converted.
To convert your STP file click the Upload button above and select the file to convert. Once selected, the file will be converted to a PLY file and will ready for download shortly afterwards. For more information about the STP to PLY conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your STP to PLY.
First click the "Upload..." button, select your STP file to upload. Select any configuration options. When the STP to PLY conversion has completed, you can download your PLY file straight away.
We aim to process all STP to PLY 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 STP file you submit to us. The resulting PLY file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our STP to PLY 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 STP 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 PLY file generated by our tool will be in the binary little endian format.
Yes! Our STP tool supports full batch conversions. You can upload up to 25 STP files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the PLY files individually or download them all in a single ZIP file.

The STP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STP files are text-based formatted files containing one instance per line.
Although STP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.
STP files when imported will be converted to 3D geometry comprising vertices and faces. If the STP file contains color information this will be converted where possible.

The PLY format is a 3D model format originally developed and released in 1994 with its primary use being to store three-dimensional data from 3D digital scanners. The format known as the Polygon File Format and also the Stanford Triangle Format can be either a binary or text based format.
The file format stores 3D geometric information such as vertices, faces, vertex normals, color and other custom data. The format is still in use with many PLY models available to download and PLY files can be loaded into most popular 3D applications such as Blender.
PLY files support per vertex color information. If your uploaded model contains color information our tool will attempt to save this in the PLY file at the end of the conversion process.
