## About

Trify3D STL Editor is a free online tool for opening, repairing and optimizing STL files directly in the browser. It handles mesh editing, geometry error fixes, scaling, rotation and print-ready export without installing any desktop software. Hobbyists, 3D printing fans and engineers can clean up broken meshes in a couple of clicks.

The editor runs entirely client-side, so models stay on your device and there is no account required. It is part of the Trify3D suite of 3D utilities at trify3d.com, which covers conversion, viewing and editing workflows for common 3D formats.
