Overview

Img2STL converts a logo, photo or drawing into a watertight, millimetre-accurate STL file for 3D printing. Pick one of four modes — raised logo, heightmap relief, lithophane or cut-out — set the real-world size, and preview the model in 3D. The basic modes run entirely in your browser, so your image is never uploaded. Optional AI modes turn a single photo into a full 3D model or a 2.5D relief. Files open in Cura, PrusaSlicer, OrcaSlicer and other slicers. The 3D preview is free; STL downloads need a credit pack (from $2.99) or a plan. Free extras include an STL viewer and 3MF/OBJ/GLB/PLY to STL converters.

Key features

Four basic print modes
Raised logo, heightmap relief, lithophane, and cut-out modes convert images to STL geometry directly in the browser.
AI 3D model generation
AI Full 3D infers unseen parts of an object from a single photo, with Quick, Standard, and Pro tiers using credits.
Watertight binary STL export
Exports closed, manifold meshes sized in millimetres, ready for any slicer like Cura, PrusaSlicer, or OrcaSlicer.
No image upload in basic modes
Basic modes run entirely in the browser, so images never leave the user's computer.
Millimetre-accurate sizing
Users set width, relief depth, and base thickness in millimetres or inches, with the model re-meshing in real time.
Keychain hole and print checks
Includes a keychain hole option and checks for thin strokes, raised backgrounds, and bed size.

Use cases

Logo keychains and signs
Raised logo mode with a transparent PNG or SVG creates keychains, badges, and signs with a solid base plate.
Photo reliefs and terrain
Heightmap relief mode turns photos, textures, and greyscale heightmaps into raised relief panels.
Lithophane lamp panels
Lithophane mode converts photos into backlit panels where brightness controls thickness.
Stencils and cut-outs
Cut-out mode produces flat shapes with through-holes, ideal for stencils, cake toppers, and pet outlines.
Full 3D models from photos
AI Full 3D generates complete 3D objects from single photos, useful for tools, cars, and other hard-surface items.
