Image to STL — free photo to STL for 3D printing

Turn a JPG or PNG photo into an STL file you can 3D print. Upload one object and our AI builds its full 3D shape — not a flat relief — then repairs the mesh and sizes it for your slicer. No account, no watermark.

No watermark, no account. STL, GLB and OBJ from one photo — 5 free models a day, the colours on the side you photographed.

A real 3D shape, not a relief

Most free "image to STL" converters make a relief: they push the photo up into a flat plate by brightness, like a lithophane or a stamp. That is useful for a light panel, but it is not the object. This tool builds the whole object in 3D from one photo — front, sides and a guessed back — so the STL prints as a figure you can hold.

Want a lithophane or a flat relief of a picture? This is not that tool; a relief generator is what you need for that.

JPG to STL, PNG to STL, picture to STL

Any common photo works as input: JPG to STL, PNG to STL, a WEBP, or a picture straight from your phone. We cut the object out of the background first, then build the mesh.

How to convert an image to STL

  1. Drop a photo of one object in the box above — a figurine, a mug, a toy, a vase.
  2. Wait about two minutes while the AI cuts it out and builds the 3D shape.
  3. Rotate the model on the page to check it.
  4. Download the STL and open it in your slicer (Cura, PrusaSlicer, Bambu Studio …).

Photos that print best

One clear object, fully in frame, seen from a slight angle so some depth is visible. People, animals and thin or see-through things (glass, wire, hair) are the hardest. From one photo the AI has to guess the back: simple and symmetric things come out well, detailed backs are plausible rather than exact. Check wall thickness and overhangs in your slicer before printing, as with any downloaded model.

How long it takes, and the limits

About one and a half to two minutes per model on our own graphics card, plus any queue.

Free: 5 models a day. Leave your email for the free monthly pass and it is 10 a day; a ShinobiTools pass gives 30 a day and works on our other tools too. Photos up to 20 MB. Your photo and the model are deleted after 45 minutes.

Common questions

Is this image to STL converter free?

Yes. Five models a day are free, with no account and no watermark. A free email pass gives 10 a day and a ShinobiTools pass 30.

Is the STL a real 3D model or a relief?

A real 3D model. The AI builds the full shape of the object, including a guessed back, so it prints as a solid figure — not a flat relief or lithophane.

Can I convert JPG to STL or PNG to STL?

Yes. JPG, PNG and WEBP photos all work. Upload one photo of one object and download the STL.

Is the STL ready to 3D print?

It is repaired after it is made and sized to 100 mm on its longest side. The page says whether the mesh is fully closed. Check wall thickness in your slicer before printing.

What kind of photo works best?

One clear object, fully in frame, seen from a slight angle. People, animals, glass, wire and hair are the hardest.

What happens to my photo?

Your photo and the model are deleted after 45 minutes. See privacy.
