Image to STL converter
Turn a picture into a raised 3D relief you can print. Your image never leaves your device.
What it does
An image to STL converter turns the brightness of each pixel into height, so a flat picture becomes a raised 3D relief saved as an STL mesh. Dark or light areas stand out depending on the invert setting, and a solid base keeps the print flat on the bed. The result is a printable plaque, sign or keychain made from any photo, logo or drawing.
How to use it
- Drop an image
Use a JPG, PNG or WebP. High-contrast pictures such as logos, line art and close-up portraits give the clearest relief.
- Set size and depth
Enter the width in millimetres, then choose the relief height and base thickness. The 3D preview updates as you move the sliders.
- Download STL or 3MF
The file is watertight and already at the size you set, so it opens in any slicer without scaling or repairs.
Examples
A close-up photo of a cat, 80 mm wide
80 × 80 × 6 mm relief with a 2 mm base
Raise the relief height to 5 mm for deeper fur texture.
A black logo on a white background
Extruded logo on a 1.6 mm plate
Turn on Invert if the logo is light on dark.
Limits and notes
- A relief is a raised picture on a plate, not a full 3D object. For a model you can see from every side, use the AI photo to 3D tool.
- Very large widths at high detail can produce files over 25 MB; detail is capped by your device's memory.
More about the Image to STL
Relief height and base thickness set how bold the print looks. A 2 mm base with 3 to 5 mm of relief prints well on most FDM printers with a 0.4 mm nozzle.
Frequently asked questions
Is my image uploaded?
No. The conversion runs in your browser with JavaScript and WebAssembly. The image and the STL never reach our servers.
What image works best?
High contrast and a simple background. Logos, line drawings and close-up faces give crisp reliefs; busy landscapes look noisy.
Which slicers can open the file?
Any slicer that reads STL or 3MF, including Bambu Studio, PrusaSlicer, OrcaSlicer and Cura.
