About
STL Kit (https://stlkit.io) is a free online converter for 3D printing and CAD files that runs entirely in your browser. Convert between 3MF, STL, STEP and OBJ formats — including Bambu Studio, Orca Slicer and PrusaSlicer project files — and export exactly the objects you need, one file at a time or all at once. Because files are parsed and written locally on your own device, nothing is ever uploaded: confidential parts stay private, and even million-triangle models open in seconds without freezing the page. Built-in mesh check reports triangle count, volume, surface area and watertight status before you export, while the 3D preview shows whether your model fits the bed of popular Bambu Lab, Prusa, Creality, Elegoo and Anycubic printers. No account, no watermark and no daily quota are required for files up to 100 MB.
