PDF (Portable Document Format) is a file format developed by Adobe to present documents independently of application software, hardware, and operating systems. It preserves the exact layout, fonts, and formatting of any document.
STL (Stereolithography) is the standard file format for 3D printing, representing surface geometry as a mesh of triangular facets. It is widely supported by all 3D printers and slicing software.

Yes, converting PDF to STL uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.
STL files are typically 50-80% smaller than PDF files because STL uses efficient lossy compression. The exact reduction depends on quality settings.
