OBJ is the plain-text workhorse of 3D: almost every modeling app, engine importer and slicer reads it. Unlike STL it can store UV coordinates and normals and point to a material file (.mtl) with textures, which makes it the usual hand-off format when a model goes into Blender, ZBrush or Maya for cleanup before printing or rendering.

That flexibility costs file size. An OBJ with color is really several files that must travel together, and it was the largest format we measured: our 1M-triangle test model came to 74.2 MB of OBJ text plus 10.7 MB of material and texture, against 49.9 MB as a binary STL.

## How to convert an image to OBJ

1. **Upload an image.** Photo, render or drawing; one subject, plain background.
2. **Sign in.** Free account, no credit card.
3. **Generate.** Check the model from all sides in the preview.
4. **Download OBJ.** Import into Blender, Maya, ZBrush, Cinema 4D or your slicer.

## Things to know

- **Keep the files together:** If an OBJ references a .mtl and textures, keep all of them in one folder or zip. Missing files mean a gray model.
- **OBJ has no units:** Blender treats 1 unit as 1 metre. Scale after import and apply the scale before modifiers.
- **Decimate before sculpting:** Generated meshes are dense. A Decimate modifier at 0.2 keeps the silhouette at a fifth of the weight.
- **Color for slicers:** The multi-color export also writes a vertex-color OBJ, which Bambu Studio can map to filaments.

## OBJ at a glance (Wavefront OBJ)

- **Stores:** Vertices, faces, UVs and normals as text
- **Color:** Via a .mtl file and texture images, or vertex colors
- **Units:** None
- **Size (our 1M-triangle test):** 74.2 MB, plus 10.7 MB of material and texture
- **Opens in:** Blender, Maya, 3ds Max, ZBrush, Cinema 4D, most slicers
- **PrintPal plan:** Free and up

### After you download the OBJ

- Keep the .obj with any .mtl and texture files in one folder, or zip them together before sharing.
- In Blender use File, Import, Wavefront (.obj). OBJ has no units and Blender treats 1 unit as 1 metre, so scale to suit your scene.
- Decimate before sculpting or rigging: a Decimate modifier at 0.2 keeps the silhouette of a 1M-triangle mesh at a fraction of the weight.
- Slicers read OBJ like STL. Bambu Studio can also read vertex-color OBJs and map their colors to filaments.
- Need STL or 3MF later? Convert it free with the [3D model converter](https://printpal.io/tools/3d-model-converter).

## Same model, every format (measured)

Same 998,810-triangle knight exported with trimesh; the GLB is the download as it came from PrintPal. The 3MF holds geometry only; a painted multi-color 3MF adds a little for the color data.

| Format | File size | Color | Units | Typical use |
|---|---|---|---|---|
| STL (binary) | 49.9 MB | No | None (slicers assume mm) | Any slicer |
| STL (ASCII) | 303 MB | No | None | Legacy CAD; avoid |
| OBJ + MTL + texture | 84.9 MB | Texture or vertex colors | None | Blender, sculpting |
| GLB (with textures) | 40.5 MB | Yes, PBR textures | Metres | Web, AR, games |
| 3MF (zipped) | 21.0 MB | Yes, per triangle | Millimetres | Bambu Studio, OrcaSlicer, PrusaSlicer |
| PLY (binary) | 27.3 MB | Vertex colors | None | Scans, point clouds |

## Real example

The treasure chest model shown on the page was generated by PrintPal from chest.png (1024 px). Raw output: 999,026 triangles, one watertight body with consistent winding. Web preview: 59,936 triangles, 446 KB GLB.

## FAQ

### Is OBJ or STL better for 3D printing?

For a single-color print they behave the same in a slicer, and STL is smaller. Choose OBJ when the model is going into another 3D app first, or when you need vertex colors.

### Can I import the OBJ into Blender?

Yes: File, Import, Wavefront (.obj). Then scale to taste, since OBJ carries no units.

### Why is my OBJ file so large?

It is text. Every vertex and face is written out as numbers, so it is larger than binary formats such as STL, GLB or 3MF.

### Is image to OBJ free?

Yes, OBJ downloads are on the Free plan with 10 generations a month.

### Can I get a textured OBJ?

Full-color generation is on Pro and downloads most easily as GLB, which Blender can re-export as an OBJ with its .mtl and textures.

### How long does a conversion take?

Draft quality usually finishes in 30 to 60 seconds. Refined and Production take longer because they build more detail, and Pro generations run on a priority queue.

### Can I sell prints of the models I make?

Yes, on Pro and Studio, which include commercial rights for prints and digital files. The Free plan is for personal use. You also need the rights to the image you upload, so stick to your own photos and artwork or images you have permission to use.
