Turn an image into a simple 3D model
Image to STL traces a 2D silhouette and extrudes it to a uniform thickness. It works for flat badges, signs and templates. A photograph only supplies the outline, so the model has no reconstructed depth.
How to use it
Upload a clear image, such as a logo, icon or silhouette.
Choose how to find the shape, then set width, thickness and detail.
Create the STL, rotate the preview and download.
Make a flat badge or raised silhouette
Give a PNG or JPG logo, icon or silhouette a uniform thickness for a prototype badge, sign or decorative piece. Separate islands produce separate solids.
Check scale, thickness and narrow details in your slicer before printing.
Choose the right image
A simple dark logo on white or a transparent PNG is easiest to use. Automatic checks for a transparent or plain background.
You can also choose the edge mode yourself. Adjust Ink sensitivity if parts of the logo are missing.
Photos do not become detailed sculpted models.
Set width and thickness
Width applies to the full image, including blank margins. The displayed model size measures just the solid logo, so it may be smaller.
Thickness adds the same depth across the whole shape. Fine detail keeps more of the edge, but curves can still look stepped.
Check separate pieces
Holes remain open through the model. Letters, dots and symbols that do not touch remain separate pieces: no backing plate is added.
Join tiny edge gaps connects corners that would otherwise keep the model from forming. A note appears when it adjusts the outline; turn this option off if you want to keep the edge unchanged.
Before 3D printing
Import the STL as millimetres in your slicer. Check the size, loose pieces, thin strokes and small holes before printing.
Choose the material and print settings in your slicer. A closed model alone does not mean every detail is practical to print.
Frequently asked questions
Will the model keep my logo colors?
No. This tool creates a single-height shape.
The STL does not keep the image’s colors.
Can all letters be joined together?
The tool does not add bridges or a base. You can add those in a 3D editor if you want one connected piece.
Why are the edges stepped?
The shape comes from an image. Try Fine detail or use SVG to STL when you have vector artwork.
