Free Online SKP to STL Converter

You can use our SKP 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 SKP to STL converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your SKP file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted SKP file before this time.

Our 3D model SKP to STL tool will load your SKP 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.

Frequently Asked Questions

How can I convert my SKP file to STL?

First, click the "Upload..." button and select your SKP file to upload. Your SKP file will be uploaded to our servers. When the SKP to STL conversion has completed, you can download your STL file right away.

How long does it take to convert my SKP to STL?

We aim to process all SKP 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.

How accurate is the SKP to STL conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting SKP to STL work?

In order to successfully convert an SKP formatted file to the STL format, our converter tools will perform several initial checks to ensure the file provided is indeed an SKP file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create SKP files to the exact specification.

Take your SKP file

An SKP file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the SKP file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated STL file size is smaller.

Convert the data from SKP to STL

Now that the data from the SKP file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final STL file format. Part of this process ensures checking the capabilities of the STL format and removing any data that cannot be represented.

Save to the STL format

At this point, the SKP to STL conversion tool will have the 3D model in a state that is ready to be transferred to the STL format. Our tool creates the STL file, ensuring all the model data is present and is formatted to match the STL file specification to ensure the file opens in compatible STL file editors. To ensure a compact file size, our SKP to STL converter will always save the STL file in a binary format.

File format information for SKP and STL

Extension	SKP
Full Name	SketchUp
Type	3D Model
Mime Type	application/octet-stream
Format	Binary

A SKP file is the native file format for the popular SketchUp 3D modelling application. SketchUp is a growing platform, popular with industrial architechs and 3D design enthusiasts alike who like the ease with which complex 3D models can be produced.

The SKP format is capable of storing complex 3D models and their associated geometric data, such as vertices, edges, faces, materials, and much more. The format is well supported, and it receives updates containing new features on a regular basis.

Due to its popularity, the SKP format is supported by many 3D modelling applications via an import option, and where an import option may be missing, our own SKP conversion tools can convert to and from the most popular 3D formats.

SKP Converter Capabilities

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

Extension	STL
Full Name	Standard Triangle Language
Type	3D Model
Mime Type	application/vnd.ms-pki.stl
Format	Text
Opens With	Blender, MeshLab, CAD Assistant, DAZ Studio

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling 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 flavours: 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.

When converting your SKP to STL, our tool will attempt to accurately convert any colour or material information.

Information for converting from SKP to STL

Your SKP file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our SKP 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both SKP and STL support colour material information, our tool will also attempt to convert the colour information.
