No. All processing happens locally in your browser using WebAssembly. Your files never leave your device — we couldn't access them even if we wanted to.
Draco is an open-source library by Google for compressing and decompressing 3D geometric meshes. It significantly reduces file size while preserving geometry, making it ideal for web, mobile, and AR/VR applications.
You can convert between STL, OBJ, PLY, and Google Draco (.drc) in any direction. All 12 format combinations are supported.
Yes. The converter is fully responsive and works on any modern browser, including mobile devices. Larger files may be slower on phones due to memory constraints.
Currently the converter handles one file at a time. Drop a new file to replace the current one — no need to reload the page.
Fast, private, and browser-based. No account needed.
