What is ImageToSTL.online?
PNG, JPG, WebP, SVG, GIF and BMP files go in and watertight binary STL files come out for 3D printing. ImageToSTL.online runs locally in the browser using Canvas and WebGL, processing files on the user device without server uploads for free modes.
Modes and local processing
Makers select from four free conversion styles including photo relief, logo extrude, lithophane, and keychain generation. Sliders adjust settings while a live 3D preview updates in real time. Transparent PNG or SVG files yield clean results for logos and silhouettes, while lithophane mode turns photographs into variable thickness panels. Exported meshes arrive as closed, manifold files with solid bases, ready to load directly into Cura, PrusaSlicer, Bambu Studio, and Orca. The tool imposes no file size caps, limits, or watermarks, and completes most jobs in under a second.
