Free browser tools for STL, OBJ & 3D-print files
Convert, repair, and edit mesh files without uploading them. Each tool runs the Cadre geometry kernel — compiled to WebAssembly — right in your browser, and opens into the full editor when a quick fix isn't enough.
- EditorEdit an STL onlineResize, cut, repair, and merge a mesh in the full editor — then export or share it for review.
- STL → 3MFSTL to 3MFPrinter-native 3MF with millimetre units baked in, for Bambu Studio, PrusaSlicer, and Cura.
- STL → GLBSTL to GLBWeb-ready glTF, scaled to real-world metres for three.js, model-viewer, and AR.
- STL ⇆ OBJSTL ⇆ OBJSwap between the two plain mesh formats, both directions, in your browser.
- STL → STEPSTL to STEPA faceted STEP solid for CNC quotes and machinist handoff — honest about the limits.
