Convert logos, photos, or drawings into STL files ready to slice and print; the basic modes run free in the browser.
About img2stl.org
img2stl.org is a 3D printing tool that converts images into STL files. Upload a logo, photo, or drawing, choose how the graphic is turned into geometry, set real-world dimensions, and download a watertight STL file. The four modes—raised logo, heightmap relief, lithophane, and silhouette cutout—run entirely in the browser and can be downloaded for free without registration; the AI full 3D model and AI relief modes call paid models and consume credits.
Best for
Best use cases
Turn a logo into a raised nameplate or sign for printing decorative pieces
Turn photos into lithophane lamp panels
Generate printable full 3D models or reliefs from photos with AI
Output files at true millimeter dimensions and drop them straight into your slicer
Features
Four print modes
Four ways—raised logo, heightmap relief, lithophane, and silhouette cutout—to turn an image into geometry ready for your slicer.
Millimeter-accurate sizes
Set real-world dimensions and output watertight STL files in millimeters.
Runs in the browser
Raised logo, relief, lithophane, and silhouette cutout upload no data—everything runs locally, and you can download without registration.
AI full 3D models and relief
AI Full 3D offers Rodin Gen-2.5 (standard), Rodin Gen-2.5 Fast (fast), and Meshy 7.1 (professional); AI relief supports setting the relief depth, and adjusting the shape afterwards is free.
Pros
- Raised logo, relief, lithophane, and silhouette cutout modes are free, require no registration, upload no data, and run entirely in the browser
- The generated mesh is watertight, dimensioned in millimeters, and sits directly on the print platform with no rotation needed
- Your first Quick AI 3D model is free after verifying your email
- Failed AI generations are automatically refunded
Cons
- The site states that it cannot guarantee every image is printable: very thin lines, very small text, and steep overhangs are inherently hard to print, no matter how clean the file is
- Unused AI mode credits reset each month (the pricing page notes: Unused models reset each month)
