Our free and fast tool will convert most 3D mesh or BLEND (Blender) 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. Our conversion tool can also batch convert multiple BLEND files; up to 25 files at a time can be converted.
To convert your BLEND 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 be ready for download shortly afterwards. For more information about the BLEND to IDTF conversion process, see the conversion information section below.

The BLEND file type is the native 3D graphics file format of the 3D modeling application Blender. Originally released in 1994, Blender has grown over the years and is one of the most popular 3D applications available.
BLEND files store 3D content such as 3D geometry, vertices, faces, normals, animations, materials, and much more. Blender is free and open-source, contains many features you would expect in a high-end 3D editing application, and is available for most current operating systems.
If your BLEND file contains texture files and other texture-related data, these will be included in the conversion process.
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.
Converting from the BLEND file format to IDTF can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your BLEND file to a valid IDTF 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an BLEND file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.
When our tool reads this 3D data, all we are interested in are the vertices, faces, and normals, as this is the only data that can be accurately converted into the final IDTF file.
The BLEND file can contain other data, such as material definitions and textures, that describe how a particular set of 3D geometry should be rendered. As we are creating an IDTF file, which does not support materials and textures, we will be ignoring this data if it is present in the BLEND file.
For more information regarding the BLEND file format, please see this great article that goes into a lot of detail explaining the BLEND format.
With the BLEND file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the IDTF format.
With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the IDTF format.
We currently support all Blender files compatible with version 4.2. We monitor and update our tool as newer versions become available.
Many 3D file conversion websites use the same off-the-shelf components to convert files, these often lack features and full BLEND file compatibility. Our bespoke file conversion tools offer full BLEND 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 BLEND file quickly and accurately with maximum compatibility.
Yes! Our BLEND tool supports full batch conversions. You can upload up to 25 and BLEND files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the IDTF files individually or download them all in a single ZIP file.
First click the "Upload..." button, select your BLEND file to upload. Select any configuration options. When the BLEND to IDTF conversion has completed, you can download your IDTF file straight away.
We aim to process all BLEND 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 BLEND file you submit to us. The resulting IDTF 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 BLEND 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 IDTF file quickly.
Yes! Our BLEND 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 BLEND 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 BLEND to IDTF, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
