PNG to STL converter
Extrude a PNG logo or icon into a 3D shape. Transparent pixels become empty space.
What it does
A PNG to STL converter reads the outline and transparency of a PNG image and extrudes the visible shape into a solid 3D mesh. Because PNG files can store a transparent background, the converter can cut the shape out cleanly instead of printing a square plate, which makes it the right choice for logos, badges, cookie-cutter outlines and name tags.
How to use it
- Drop a PNG
A logo or icon with a transparent background gives a clean cut-out. A white background works too; set the threshold to drop it.
- Choose thickness
Set the width in millimetres and how tall the extrusion should be. Add a backing plate if the design has loose parts.
- Download
Save as STL or 3MF and print it flat on the bed.
Examples
512 × 512 PNG logo with transparency, 60 mm wide
60 mm wide logo, 3 mm tall, no plate
Limits and notes
- Fine lines thinner than about 0.8 mm at the chosen size may not print on a 0.4 mm nozzle; make the design larger or bolder.
More about the PNG to STL
For multi-colour prints, export each colour of the logo as its own PNG and convert them one by one at the same width so the parts line up.
Frequently asked questions
Do I need a transparent PNG?
No, but it helps. With a solid background, raise the threshold until only the shape remains in the preview.
Is the PNG uploaded?
No. Everything runs in your browser.
