Convert Blender (.blend) to OBJ for Broad Compatibility
Upload a .blend and get a ZIP with the OBJ, its MTL and the image textures, exported by Blender itself with your modifiers applied. Pack your textures into the file first (File > External Data > Pack Resources): images stored elsewhere on your disk cannot reach our server.

Why convert BLEND to OBJ?
A .blend file is Blender's own save format. It holds the whole session: every scene, collection and modifier stack, node-based materials, links to other .blend files, and the state of the viewport. Only Blender opens it in full, so anyone without Blender installed, or working in another program, needs an exported mesh instead. OBJ is the safe pick when the receiving software is unknown.
We open your file with Blender 5.1 on our servers, the same way the desktop app opens it, not through a third-party parser. Collections you excluded with the checkbox are switched back on, objects left in Edit Mode are returned to Object Mode, and curves, text and metaballs are turned into polygon meshes. Blender's OBJ exporter then writes the scene with every modifier applied at its viewport settings, including Geometry Nodes output and collection instances.
The OBJ keeps the final shape of each object, its name, UVs and normals. Image textures wired into the Principled BSDF are copied next to the OBJ and linked in the MTL (base color as map_Kd, normal map as map_Bump). Procedural shader nodes have no MTL equivalent and are left out. Lights, cameras and armatures are not geometry, so they are skipped, and animated or rigged meshes are written in a single pose. Objects you hid with the eye icon stay out of the export, unless every object in the file is hidden.
This is what people mean by blend to obj or blender file to obj: a student or client receives a .blend, a 3D printing user needs a mesh their slicer can read, or a game modder wants a model in a format their tools import. Coordinates are written in Blender units, normally meters, so a slicer that reads numbers as millimeters needs the model scaled up.
How to convert a Blender file to OBJ
- In Blender, run File > External Data > Pack Resources so the textures travel inside the .blend, then save. If the file links models from other .blend files, make them local or pack the linked libraries too.
- Set each Subdivision Surface modifier's viewport level to the detail you want in the OBJ, since the viewport settings are what get applied.
- Upload the .blend. Compressed .blend files are fine, and you can add up to 10 files in one batch.
- Download the ZIP (named like scene.obj.zip) and extract it, keeping the .obj, .mtl and images in the same folder.
- Open or import the .obj in your target program. For 3D printing, check the scale in the slicer before slicing.
What the BLEND to OBJ converter does
- Opens the real .blend in Blender 5.1, so modifiers, Geometry Nodes and instances are evaluated as Blender sees them
- Re-enables excluded collections and recovers files saved in Edit Mode
- Turns curves, text and metaballs into polygon meshes before export
- Copies packed and relative-path image textures into the ZIP under the OBJ's name
- Explains the problem when a file only links its models from other .blend files or has no geometry

BLEND to OBJ: questions and fixes
How do I convert a .blend file to .obj without Blender?
Upload it above. Blender runs on our server, opens your file, applies the modifiers and exports OBJ with an MTL and the image textures, zipped into one download. You do not need Blender on your own computer.
Why are my textures missing from the OBJ?
Your .blend most likely points to image files on your own disk. Only the .blend reaches our server, so those images cannot be found and the OBJ is exported without them. Pack them with File > External Data > Pack Resources and save. Alternatively, zip the .blend together with its texture folder, keeping the relative paths, and use our ZIP to OBJ page. Procedural textures made from shader nodes never transfer; bake them to images in Blender first.
What does "No valid 3D objects found in scene after import" mean?
Blender opened the file but there was nothing it could export as a mesh. We already unhide hidden objects, look in other scenes and link unplaced collections before giving up, so this usually means the file holds only lights, cameras or empties, or that the models live in another .blend that was not uploaded. Add the model to the scene, make it local, save and upload again.
Why do I get ERROR_3D_UNREADABLE?
Blender could not read the file at all. Common causes are an upload or download that was cut short, an autosave Blender was still writing, or a file that is not a .blend despite its name. Open it in Blender on your machine, save it again with File > Save As, and upload the fresh copy.
Which Blender versions are supported?
Our server runs Blender 5.1, which opens files saved by older Blender versions. A file saved by a Blender release newer than ours may not open; if you see a message about a newer version, save a copy from a compatible version or export OBJ, FBX or GLB from your own Blender and convert that.
Do I have to apply my modifiers before uploading?
No. The OBJ exporter applies every modifier using its viewport settings, so mirrors, bevels, arrays and booleans come out as you see them in the viewport. Only set the viewport subdivision level you want, because a higher render level is not used.
Why is an object from my scene missing?
Objects hidden with the eye icon or the monitor icon are left out, which is how Blender's OBJ exporter treats them, unless every object in the file is hidden. Unhide the object and save before uploading. Objects in collections you excluded with the checkbox are switched back on and exported.
What happens to my .blend after the conversion?
It is processed on our servers and erased as soon as the conversion finishes. Download the ZIP within 4 hours; the link stops working after that and the server copy is purged.
