JPG to OBJ converter from a single photo
Photogrammetry needs dozens of overlapping shots. PrintPal needs one JPG. Upload a photo of an object and download an OBJ of the whole thing.

This model was generated by PrintPal from the image beside it. Spin it, then switch to STL (no color) to see exactly what a single-color print gets.
Input: chest.png, 1024 pxWood planks, gold bands, rivets and a gem lock: fine surface relief for a tabletop prop or dice box.

Each example is one AI-generated 1024 px PNG run through PrintPal's full-color image-to-3D at high detail, with no editing afterwards. Mesh checks were run on the raw download with trimesh. The preview is simplified to about 60,000 triangles so it loads fast; your download keeps full detail.
JPG to OBJ: what actually happens
Turning photos into an OBJ used to mean photogrammetry: walk around the object taking 30 to 100 overlapping pictures, then wait while software stitches them together. That still gives the most accurate digital copy, but it is slow and fails on shiny, transparent or featureless surfaces.
Single-image AI trades exact measurements for speed. From one JPG it infers the full shape, which is ideal for figurines, decor, props and gifts, and good enough as a reference mesh for products you will refine in CAD. For parts that must fit precisely, measure the real object and use the AI CAD agent or the image to CAD workflow.

- Typical source
- Phone and camera photos, most images on the web
- Watch out for
- Re-compressed copies from social apps (blocky artifacts)
- Background: Separated from the subject automatically; plain backgrounds work best.
- Orientation: The EXIF rotation from your phone is applied before upload.
- Compression: Heavy artifacts can read as surface bumps, so use the original file.

Tips for a better OBJ
AI or photogrammetry?
Use AI for speed and for objects you only have one picture of. Use photogrammetry when you need a measured replica of something on your desk.
Matte beats shiny
Reflections and glossy highlights confuse both methods. Photograph glossy objects in diffuse light, away from windows behind you.
Scale it yourself
A photo carries no scale. Measure the real object and scale the OBJ to match in Blender or your slicer.
Expect a dense mesh
Around 500k triangles at Draft quality. Decimate it before sculpting or animating.
From a phone photo to a printed object
Casual photos, not studio shots. Each one was generated on PrintPal and printed on a desktop printer.

One model, every format
We exported the same 998,810-triangle generation to each format and measured the files.
| 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 |
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.
After you download the OBJ
The checklist we use before printing a generated 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.
