Everything you need to convert PNG to STL
A complete PNG to STL converter pipeline, running locally in your browser — from upload to a watertight, print-ready STL or 3MF file.
Private & browser-native
Images are decoded and meshed entirely in your browser. Nothing is uploaded to any server — ever.
Pro geometry controls
Tune relief height, edge bevel, base plate, contrast and edge subdivision for a watertight, print-ready mesh.
Realistic material preview
Preview in steel, copper, gold, white, black or translucent (lithophane) — see the print before you print.
Colored surface mapping
Map the original image colors or brightness to vertex colors; 3MF keeps the full surface texture.
STL & 3MF export
Standard STL for every printer & CNC, 3MF with color for modern pipelines. No watermark, no paywall.
No account needed
Open the tool and go. Core features are free, ad-light, and ready in under 3 seconds.
