What is a BLEND file?

A BLEND file is a 3D image or animation project created with Blender, an open-source 3D modeling program. It contains 3D mesh data, lighting information, vertex painting, animation keyframes, NURBS objects, procedural textures, UV mapping layout, and real-time interactivity data. BLEND files may store multiple scenes in a single file.

Blender is a free, multiplatform application for creating various 3D productions, including models and animations. When saving the 3D image or animation you created in Blender, the application generates a BLEND file to store its contents. After saving the BLEND file, you can close the file, then re-open it for further editing.

Unlike many other types of project files, BLEND files contain all the objects, sounds, images, effects, scenes, and other assets included in a Blender project. If you want to share a Blender project with another user, you need only provide them with that project's BLEND file, not any of the assets you imported into the project.

NOTE: BLEND files are saved in a proprietary binary format to keep them from growing to an unmanageable size.

How to open a BLEND file

You can open a BLEND file with Blender (cross-platform). To do so, select File → Open... from the program's menu bar. Then, navigate to and open your BLEND file. The 3D image or animation your BLEND file contains will appear in Blender.
