How to convert Image to STL
A compact workflow for turning image files into STL geometry for printing, slicing, and mesh editing.
01Upload a supported image.
02Adjust print-friendly settings.
03Preview the model.
04Export binary STL.
05Open the STL in a slicer.
Use Cases
The first version focuses on the conversion surface users expect: upload, tune, preview, and download.
Heightmap experiments
Use grayscale or high contrast images to test relief-style STL generation.
Fast browser workflow
The first version focuses on a fast conversion interface before adding advanced depth modes.
FAQ
Short answers for the practical conversion questions users ask before downloading an STL file.
Can I use the STL file for 3D printing?
Yes. The downloaded STL can be opened in most slicers, including Cura, PrusaSlicer, Bambu Studio, and OrcaSlicer.
Why does my STL look flat?
Increase the model height or use an image with stronger contrast. Low contrast images produce smaller height differences.
Does STL keep colors?
No. STL stores geometry only. It does not preserve image colors or textures.
