png to stl model — lift any flat image into a tactile 3D relief
png to stl converter runs entirely on your device. Drop in a PNG or JPG and watch it become a solid, watertight relief mesh you can export as STL or 3MF — no servers, no sign-ups, no waiting.
Upload an image to generate
A PNG-to-STL pipeline that lives in your browser
From a single image to a slice-ready STL or 3MF — every step happens locally, so your artwork stays private and your workflow stays instant.
Stays on your device
Your image is decoded and meshed inside the browser tab. It is never transmitted, cached, or stored anywhere else — the whole pipeline is local.
Tactile geometry controls
Shape relief depth, rounded edge, base thickness, contrast and subdivision to get a clean, watertight mesh that prints the first time.
Preview real materials
Spin the model in steel, copper, gold, white, black or frosted lithophane and see the finished piece before you ever send it to a printer.
Keep the color
Paint the surface from the source image or its brightness; 3MF stores the full color texture for modern color printers.
STL & 3MF out
Universal STL for any printer or CNC, color-rich 3MF for modern workflows. No watermark, no paywall, no resolution cap.
Ready in seconds
