A SKP file is the native file format used by the SketchUp 3D modeling application. The SketchUp application started out in 2000 and has been maintained with newer versions featuring improved features ever since.
Other than SketchUp itself, support for opening SKP files within other 3D model editors is limited. There is a C++ API to help developers integrate the format into their own code and build extensions for SketchUp.
Mesh Geometry
The SketchUp SKP format supports mesh geometry composed of vertices and faces. There is also support for texture coordinates and other advanced 3D content.
SKP Converter Capabilities
As materials containing color information is supported by the SKP format, our tool will do its best to include this in the converted file.

The STL file format is used for storing 3D models and is a common format for distributing 3D printable models. STL files emerged in the 1980s as a format for storing a 3D mesh as a simple list of triangles. Due to its age and simplistic format, it has gained widespread support within 3D modeling and CAD applications.
As a result of the simple file format and its widespread support amongst 3D editors, the STL format has found itself as the format of choice for the distribution of 3D printable objects. There are many websites that offer 3D printing downloads in the STL format.
Mesh Geometry
As mentioned, STL files make use of a simple structure for containing the 3D mesh data. The 3D model is stored as a continuous list of triangles, with each triangle containing three vertices specifying the location in 3D space of the triangle, which, along with a single vector normal, is all that is required to render the model contained within the STL file. There are two formats of STL files: plain text and binary. When used with large and complex 3D models, the text format leads to very large file sizes and should be avoided, with the binary format offering more efficient storage of the mesh data.
