The PNG graphics file format is a commonly used format for storing 2D images which can be highly compressed by the use a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.

PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990's as a superior format to GIF. PNG files are generally used for company logos, icons and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image hence the PNG format being unsuitable for most digital photo content.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.

There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

Information for converting from PNG to STL

Our PNG converter will convert your PNG file to a 3D model using the Heightmap process whereby 2D pixels, based on their luminosity, are converted into 3D space to create a full 3D STL model ready for download for further processing in your favourite 3D editing package or for printing on a 3D printer.
