Convert Your 3D Mesh/Model STL Files to FBX

to

Our free and fast tool will convert most 3D mesh or STL (Standard Triangle Language) model files to a standard FBX (Autodesk Filmbox) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing.

To convert your STL file click the Upload button above and select the file to convert. Once selected, the file will be converted to a FBX file and will ready for download shortly afterwards. For more information about the STL to FBX conversion process see the conversion information section below for more information.

Upload a STL

Click the "Upload a STL File" button and select a STL to upload. The maximum file size is 100MB.

Download your FBX

Click the download link once completed to receive your FBX file.

What STL formats can I convert from?

You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.

How can I convert my STL file to FBX?

First click the "Upload..." button, select your STL file to upload. Select any configuration options. When the STL to FBX conversion has completed, you can download your FBX file straight away.

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

We aim to process all STL to FBX conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the STL to FBX conversion?

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.

Is it safe to convert my STL to FBX on ImageToStl.com?

Yes, of course! We do not store the STL file you submit to us. The resulting FBX file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert STL to FBX on Windows, Linux, Android, iOS or Mac OS?

Yes! Our STL to FBX tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

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.

Description

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.

STL Notes

Standard STL files do not contain material or color information so this cannot be imported. There are however two formats (VisCAM and SolidView) that attempted to add color information to the STL file format. If our tool detects this additional color information it will attempt to import this information.

Description

The FBX format by AutoDesk was originally developed by Kaydara in the 1990s as a means to store 2D or 3D content with motion data. It has evolved over the years to become a widely used format by 3D modelling applications such as Blender, 3D Studio Max and others due to its 3D animation capabilities.

The format is used to contain 3D models which includes vertices, faces and other 3D geometry along with animation data. The format is proprietary however there is a publicly available API to use for development purposes. The file contents can be either text or binary and work has been carried out by the Blender Foundation to document the format.
