Converting a JPG to STL
A JPG-to-STL converter turns a photo into a 3D print by mapping brightness to height. JPG is the common format for photographs, so it's ideal for making a relief or a backlit lithophane from a picture or portrait.
Drop the JPG, pick relief or lithophane, set the width and thickness, preview in 3D, and download a slicer-ready STL. Because JPG has no transparency, the whole frame becomes part of the model — crop it first if you only want the subject. It all runs in your browser: no upload, no signup, no watermark.
Frequently asked questions
- How do I convert a JPG to STL?
- Drop your .jpg or .jpeg above, choose relief or lithophane, set the size and thickness, and download the STL. Each pixel's brightness sets how tall that point is.
- Can I 3D print a photo from a JPG?
- Yes — JPG is the usual format for photos. For a portrait or pet photo, use lithophane mode and print it a few millimetres thick so the image appears when backlit.
- Is the JPG to STL converter free?
- Yes — free, no signup, no watermark, and no file-size paywall. It converts locally in your browser.
- Does my JPG get uploaded anywhere?
- No. There is no server and no upload — the JPG is converted on your device and nothing is stored.
