Description
The PNG to STL Converter from 3DPEA is a free online tool that transforms PNG images into 3D STL model files suitable for 3D printing or importing into other 3D editing software. Users upload a PNG, choose conversion options, and download the resulting STL file, with no login or signup required.

The tool offers several conversion modes: Standard produces a smooth, heightmap-style model based on image brightness, Standard Color adds color detail, and Extrude and Extrude Color create distinct layered shapes from the image. A conversion handbook explains each setting, including width, height, depth, and segment resolution, border options, base thickness, color merging, transparency handling, aspect-ratio locking, output inversion, smoothing, and Z-axis mirroring.
3DPEA also supports many other model output formats, including 3MF, AMF, OBJ, FBX, 3DM, GLB, glTF, PLY, DRC, and ZIP, and provides additional PNG conversion tools for other formats. It works across Linux, Android, iOS, and macOS since it runs online.
3DPEA describes itself as an independent online community for 3D designers and creators, built by a small team of indie developers. Alongside converters, it hosts free 3D models, a 3D editor and viewer, a GCode simulator, and a DICOM viewer to streamline 3D printing, CNC, and laser-cutting workflows.
