# PNG to 3D model in the format you need

> One PNG in, one full 3D model out. Download it as STL for printing, OBJ for editing, GLB for the web, or as a multi-color 3MF for your AMS.

Turning a PNG into a 3D model involves two decisions: how the depth gets made (AI reconstruction, heightmap relief or extrusion) and which file you need at the end. This page helps with both, and each format links to a page that goes deeper.

Printing? Choose STL for one color or 3MF for several. Editing in Blender? OBJ. Putting it on a website or in AR? GLB. Not sure yet? Start with STL; the same generation can be downloaded again in any format your plan includes, and the free [3D model converter](https://printpal.io/tools/3d-model-converter) covers the rest.

## How to convert PNG to 3D model

1. **Upload a PNG.** One subject, transparent or plain background, at least 512 px.
2. **Sign in.** Free account, no credit card. Your PNG comes with you.
3. **Generate.** About a minute at Draft quality.
4. **Pick a format.** STL and OBJ on Free; GLB, PLY and multi-color 3MF on Pro.

## Things to know

- **Printing in one color:** Download [STL](https://printpal.io/convert/png-to-stl). Every slicer reads it.
- **Printing in several colors:** Generate in full color and use the multi-color export for a [3MF](https://printpal.io/convert/png-to-3mf) with each color on its own filament.
- **Editing or sculpting:** Download [OBJ](https://printpal.io/convert/png-to-obj) for Blender, ZBrush or Maya.
- **Web, AR or games:** Download [GLB](https://printpal.io/convert/png-to-glb): one file with mesh and textures.

## PNG at a glance (Portable Network Graphics)

- **Type:** Raster, lossless
- **Transparency:** Yes, full alpha channel
- **Typical source:** Logos, digital art, renders, AI images, product cutouts
- **Watch out for:** Screenshots with UI, sprite sheets, tiny icons
- **Transparency in the conversion:** Used as the cutout, so the AI knows exactly where your subject ends.
- **Colors in the conversion:** Projected onto full-color models (Pro). STL drops them.
- **Resolution in the conversion:** Scaled to 2048 px on the long side in your browser; larger adds nothing.

## 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 mushroom house model shown on the page was generated by PrintPal from cottage.png (1024 px). Raw output: 998,594 triangles, one watertight body with consistent winding. Web preview: 59,910 triangles, 365 KB GLB.

## FAQ

### Can I convert a PNG to 3D for free?

Yes. The Free plan includes 10 generations a month with STL and OBJ downloads, at Draft quality, without a credit card.

### Which 3D format should I pick?

STL for single-color printing, 3MF for multi-color printing, OBJ for editing in other 3D apps, and GLB for the web, AR and game engines. The table further down compares them using real file sizes.

### Can I download one model in several formats?

Yes. A finished generation can be downloaded again as STL, OBJ, GLB or PLY, depending on your plan, without generating it again.

### How accurate is PNG to 3D?

The front and silhouette follow your PNG closely. The sides and back are inferred, so they are plausible rather than exact. Symmetric, familiar subjects come out best.

### Can I use AI-generated PNGs?

Yes, and they often work very well: AI image models produce clean, evenly lit renders on plain backgrounds, which is the ideal input. All three example models on this page started as AI-generated PNGs.

### 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.
