BLEND file format information

Full NameBlender
Type3D Model
Mime Typeapplication/octet-stream
Opens WithBlender

The BLEND file extension is the native 3D modelling file format of the ever-popular Blender 3D modelling software. The Blender format originally came into existence in late 1994 and has since evolved into the advanced 3D format we have today.

The format stores complex 3D mesh data along with textures, animations, lighting, and other information related to 3D scene rendering. The format is popular among those creating 3D videogame graphics and animation sequences due to its advanced features and ease of use.

Along with Blender, BLEND files can also be imported into other popular 3D editing software. The open-source nature of the format allows third-party plugins and scripts to be created to run within the Blender editing environment and extend the format's capabilities.

Repairing a BLEND File

BLEND 3D Model File Header Data

As is common amongst 3D model file formats, BLEND file formats may contain data within their header to help identify the type of file should the filename extension prove to be inaccurate or missing. With the header data from the BLEND 3D model file, we are able to determine core information such as object count, vertex count, faces, textures, and other information, which can then be used to check the validity of the file.

Vertices, Faces and Geometry

This data forms the core element of any BLEND model and, if damaged, cannot be easily recovered. Our BLEND repair tool will try its best to repair and reconstruct any 3D model file it detects to be missing geometric data.


With some 3D model file formats, such as BLEND, textures are stored as separate files. If these are missing, they will not be able to be restored. Our tool will detect these external texture file references and ignore them. For other formats where the textures are embedded within the main 3D model file, these will be repaired where possible.

Frequently Asked Questions

Will the quality (vertices or faces) be affected?

Our BLEND repair tool will not intentionally reduce the number of vertices or faces in your 3D model.

Is it free to use the BLEND file repair tool?

Yes! Our BLEND repair tool is 100% free to use.

Are there any usage limits when repairing my BLEND file?

No, you can repair as many files as you wish. We do not have any limits when using our BLEND repair tool.

How long does it take to repair my BLEND?

We aim to process BLEND repairs as quickly as possible; this usually takes around 5 seconds; however, this may be longer depending on the file size and data needed to be repaired.

What does the BLEND repair process involve?

Once your BLEND has been selected, it will undergo some initial checks to verify that the file has some basic information. If the initial checks pass, we then upload the file to our servers for more detailed analysis.

Is it safe to repair my BLEND on

Yes, of course it is! Your BLEND, once repaired, is deleted 15 minutes after upload, and any download link will expire after this time.

Can I repair my BLEND on Windows, Linux, Android, iOS or Mac OS?

Yes! Our BLEND repair tool will run on any system with a modern web browser.
