PNG to STL: what carries over and what does not

PNG is made of pixels and STL is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a STL container, and that determines whether a CAD or design tool can work with it.

PNG to STL Conversion: FAQ

What are PNG files?

The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems.
