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.

STL Converter Capabilities

When converting 3D Model/Mesh files using our STL converter we will attempt to convert color materials into a suitable format for use in the converted file.

An MP4 file is a modern standard format for storing high-quality motion video in a highly compact and efficient file size. The specific compression algorithm used within an MP4 file can vary from file to file; however, they all enable what would otherwise be a large amount of uncompressed data to be reduced to a fraction of the original size with little or no noticeable difference in playback quality.

Due to its widespread support, MP4 files can be loaded into most video editing applications and played with most video playback software with no additional drivers. Most video sharing sites, such as YouTube, support MP4 as a format when uploading, and most tablets and smart phones can record in the MP4 format.

Audio stored within an MP4 file is usually stored in the MP3 format, taking advantage of that format's high quality and compression capabilities.

Information for converting from STL to MP4

The STL 3D format does not support animations within our conversion tool so our tool will create a simple 360 degree rotating 3D animation that will be rendered to a MP4 file ready for download.

Frequently Asked Questions

How can I convert my STL file to MP4?

First click the "Upload..." button, select your STL file to upload. Your STL file will be uploaded to our servers. When the STL to MP4 conversion has completed, you can download your MP4 file straight away.

How long does it take to convert my STL to MP4?

We aim to process all STL to MP4 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 STL to MP4 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 is my STL 3D model animated in the MP4 file?

If your STL file contains an animation then our tool will create a MP4 file containing the full length animation. If there is no animation present our tool will use a simple rotation animation.
