Create 3D animations with our easy-to-use and free tool. Our tool lets you upload a STL (Standard Triangle Language) 3D model file, and from this, create an animated MP4 (MPEG-4) file that you can then download and share without the need for any complex 3D modeling software.
Our STL to MP4 animation tool includes options to adjust the camera position within the 3D world, set the resolution of the generated MP4 file, and, if your STL file contains any animations, allow you to set the animation to play. To get started, please click the Upload button and select your STL file.
Here are three simple steps to create an MP4 file from a STL file.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.
There were several formats that attempted to extend the STL format, namely SolidView and VisCAM, whose formats included limited 15-bit color information for each mesh face, which is often ignored by most modern 3D software. The STL format can be either text or binary; our tools will support both formats.
Standard STL files do not contain material or color information, so this cannot be imported. There are, however, two formats (VisCAM and SolidView) that attempt to add color information to the STL file format. If our tool detects this additional color information, it will attempt to import this information.
| Extension | MP4 |
| Full Name | MPEG-4 |
| Type | Video |
| Mime Type | video/mp4 |
| Format | Binary |

The MP4 video format is a standard format for video encoding and storage. In order to minimize file sizes, the format employs a lossy compression method that reduces the amount of data needed to store the video content without any noticeable loss in quality.
Due to its small size and efficient compression methods, the MP4 format is ideally suited for online video streaming. The MP4 format may use a variety of CODECs, which are usually supported by most MP4 players, with additional CODECs downloadable if needed.
You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full STL file compatibility. Our bespoke file conversion tools offer full STL file compatibility and have been developed in-house by a team of developers, some of whom have over 30 years of experience working with 3D graphics file formats, meaning our tools will convert your STL file quickly and accurately with maximum compatibility.
First click the "Upload..." button, select your STL file to upload. Select any configuration options. When the STL to MP4 conversion has completed, you can download your MP4 file straight away.
We aim to process all STL to MP4 conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the STL file you submit to us. The resulting MP4 file, once created is deleted 20 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your STL file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted MP4 file quickly.
Yes! Our STL to MP4 tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our STL conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your STL to MP4, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
