Preview your .stl here, then slice it into G-code with a real slicer — we'll explain why.
Generating real G-code requires a full slicer (PrusaSlicer, Cura, Bambu Studio) — they need printer profile, layer height, infill, supports. Preview your STL here, then drop it into your slicer of choice.

G-code is a sequence of motor instructions specific to your printer, filament, layer height, infill pattern, support strategy and dozens of other parameters. There's no universal "STL → G-code".
A browser tool can't pick the right speed for your specific Bambu A1 with PETG vs your Prusa MK4 with PLA. Use PrusaSlicer, Cura, Bambu Studio or OrcaSlicer — all free, all desktop, all open-source.
The file is parsed in WebAssembly + WebGL on your device. Nothing leaves.
No queue, no upload. Most files convert in well under a second.

Honest answer: slicing well is the hard problem of 3D printing. We won't ship a toy slicer that produces bad prints. Preview your STL here, slice with the real thing.
Bambu Studio if you have a Bambu printer. PrusaSlicer for Prusa, Voron and most other FDM. Cura for legacy printers.
Yes — every slicer reads STL natively. No conversion needed.
