Free Online STL to MP4 Converter

Our STL to MP4 converter will take the 3D model contained within your STL file and create a simple animated video file that will be saved to the MP4 format. You may upload up to 20 files at one time and have them batch converted to the MP4 format.

Select File(s)

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

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

File information for STL and MP4

Full Name	Standard Triangle Language
Extension	STL
Type	3D Model
Mime Type	application/vnd.ms-pki.stl
Format	Text

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.

STL Converter Capabilities

As materials containing color information is supported by the STL format, our tool will do its best to include this in the converted file.

An MP4 file is a popular file format for storing video; it has become one of the most widely supported video formats and can be opened on most devices without the need for any additional software.

One of the reasons for its popularity is its ability to compress raw video down to a manageable size without any noticeable loss of detail. It does this by using some clever lossy compression algorithms to remove detail from the video sequence that would otherwise not be noticeable to the human eye.
