You can use our PLY to STL conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch PLY to STL converter will process each 3D model and present you with a download link for each file once completed.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
Our 3D model PLY to STL tool will load your PLY file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.
Here are two simple steps to convert your PLY to STL using our fast and free PLY converter tool.
First, click the "Upload..." button and select your PLY file to upload. Your PLY file will be uploaded to our servers. When the PLY to STL conversion has completed, you can download your STL file right away.
We aim to process all PLY to STL conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.
Our PLY tool will read all the vertex information from your STL file and use only this information when creating the final STL file.

The PLY format, also known as the Standard Triangle Format, is a popular 3D model file format originally created by Stanford University in the 1990s as a means to store 3D model data in a flexible and expandable format. There can be both binary and ASCII text formats in PLY files.
Both binary and text formats share a common header section that defines what geometric attributes (such as vertices, normals, faces, and colors) are present in the data. It is also possible to specify custom data to be associated with a vertex or object face.
PLY files can be opened with a wide range of 3D editing software; for example, Blender can both import and export to the PLY format with no additional software required.

When converting 3D model or mesh files using our PLY converter, we will attempt to convert color materials into a suitable format for use in the converted file.

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
STL Converter Capabilities
When converting your PLY to STL, our tool will attempt to accurately convert any color or material information.
Your PLY file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our PLY 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both PLY and STL support color material information, our tool will also attempt to convert the color information.
