Transparent PNG support
Transparent areas can become empty or low-height regions, which is useful for logos, stamps, and icons.

PNG to STL Converter
Convert PNG images into STL files for 3D printing. This tool works well for logos, icons, black-and-white artwork, heightmaps, and transparent PNG images.
How to convert PNG to STL
A compact workflow for turning png files into STL geometry for printing, slicing, and mesh editing.
01Upload your PNG file.
02Set the model height and base thickness.
03Choose whether to invert the height.
04Preview the 3D result.
05Download the STL file.
Use Cases
The first version focuses on the conversion surface users expect: upload, tune, preview, and download.
Sharp edge conversion
PNG files preserve clean edges better than compressed photos, making them a strong format for raised geometry.
Logo relief models
Upload a high contrast PNG logo and tune the height settings to create a simple 3D printable relief.
FAQ
Short answers for the practical conversion questions users ask before downloading an STL file.
Can I convert a transparent PNG to STL?
Yes. Transparent areas can be treated as empty or low-height areas depending on the converter settings.
Is PNG better than JPG for STL conversion?
Usually yes. PNG often keeps sharper edges and fewer compression artifacts, which can create cleaner STL geometry.
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.
