"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

STL to PNG Conversion: FAQ

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems. STL is an acronym for Stereolitography, which is a type of technology used for creating prototypes or patterns through 3D printing. An STL file contains a surface representation of such a model, without detailed specifications of aspects such as colours. STL files can only be opened with a limited number of programs.

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.
