Our free and fast tool will convert most 3D mesh or STL (Standard Triangle Language) model files to a standard IDTF (PDF With integrated 3D Models) 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 IDTF file and will ready for download shortly afterwards. For more information about the STL to IDTF conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your STL to IDTF.
You can convert from both text and binary STL files. If your STL file contains color information we will bring this over.
First click the "Upload..." button, select your STL file to upload. Select any configuration options. When the STL to IDTF conversion has completed, you can download your IDTF file straight away.
We aim to process all STL to IDTF 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 IDTF file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STL to IDTF 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.
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 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.
|Full Name||PDF With integrated 3D Models|
The IDTF file format is a bespoke format that enables interactive 3D content to be embedded within a PDF document. Currently only Adobe Reader and PDF-XChange Editor are able to render PDF documents that contain this 3D content.
IDTF files are a simple text-based format containing 3D geometry defined using vertices and faces in a structured hierarchy. Prior to importing the IDTF file to the PDF it must be converted to a U3D file format using one of the free applications such as IDTFConverter.
Currently only mesh geometry will be carried over from your source model to the final IDTF file for download.
