Conversion · Analysis · Repair · Optimisation · Generation · Utility. Every tool processes your meshes locally with three.js — zero bytes uploaded.
Every JAD 3D tool runs entirely in your browser using three.js and WebGL. Open DevTools and watch the Network tab during processing — you'll see zero requests to any server. Your meshes never leave your device.
STL ↔ OBJ ↔ GLB ↔ USDZ converters, ASCII/binary STL switching, and unit conversion (inches ↔ mm).
Convert STL files to GLB (binary glTF) directly in your browser. Smaller, faster, and AR-ready. Zero upload — your meshes never leave your device.
Open toolConvert Wavefront OBJ files to Apple USDZ for iOS AR Quick Look. 100% browser-based — no upload, no server, no Mac required.
Open toolConvert STL meshes to Wavefront OBJ in your browser. Open the result in Blender, Maya, Cinema 4D, or any 3D tool. Privacy-first — zero upload.
Open toolConvert Wavefront OBJ files to STL for 3D printing slicers (Cura, PrusaSlicer, Bambu Studio). Browser-based, zero upload, free.
Open toolExtract mesh geometry from a GLB (binary glTF) file and save it as Wavefront OBJ. All processing runs in your browser — no upload.
Open toolConvert ASCII STL files to compact binary STL — typically 5× smaller. Faster to load, cheaper to store. 100% browser-based, no upload.
Open toolConvert binary STL files to human-readable ASCII STL. Diff models, version-control geometry, or debug malformed meshes. Browser-based.
Open toolRescale STL/OBJ/GLB meshes between inches, cm, and mm in one click. Browser-based — no upload, no calibration headaches.
Open toolVolume, surface area, bounding box, polygon counts, wall thickness, centre of mass, and metadata inspection.
Compute the exact volume of any STL/OBJ/GLB mesh in cm³ and estimate weight for PLA, ABS, PETG, resin, and 8 metals. Browser-based.
Open toolCompute the X/Y/Z bounding box of any STL, OBJ, or GLB mesh. Get exact print dimensions in mm — useful for fitting models to your printer bed.
Open toolReveal the 80-byte STL header, GLB JSON chunk, software origin, vertex/face stats, and authoring tool from any 3D file. Browser-based, zero upload.
Open toolGet exact vertex, edge, and face counts for STL, OBJ, and GLB files. Useful for performance budgeting in games, AR, and 3D printing.
Open toolCompute the exact surface area (mm²) of any STL, OBJ, or GLB mesh. Useful for paint estimates, plating cost, and resin coating calculations.
Open toolFind walls thinner than your minimum print threshold. Ray-cast across the mesh to detect thin sections that may fail to print or break. Browser-based.
Open toolCompute the centroid (centre of mass) of any STL/OBJ/GLB mesh assuming uniform density. Useful for balance, animation pivots, and engineering analysis.
Open toolHole-fill, manifold checks, duplicate face removal, normal recomputation, and vertex colour stripping.
Fix problem STL meshes: weld duplicate vertices, remove degenerate faces, and detect non-manifold boundaries. Browser-based, zero upload.
Open toolStrip duplicate triangles and zero-area faces from STL/OBJ meshes. Smaller files, faster slicing, fewer printer errors.
Open toolRecompute consistent face and vertex normals on any STL/OBJ/GLB. Fixes inverted shading, missing normals, and flipped triangles.
Open toolRemove per-vertex colour data from CAD-exported STL/OBJ/GLB files. Cleaner geometry for downstream pipelines that don't accept vertex colours.
Open toolPolygon decimation, Laplacian smoothing, axis flipping, print orientation, and printer-bed scaling.
Decimate STL/OBJ/GLB meshes to a target polygon count. Quadric-error simplification preserves silhouettes. Browser-based, no upload.
Open toolSmooth out faceted scans, low-poly meshes, and CAD exports with Laplacian smoothing. Adjustable iterations and lambda. Browser-based.
Open toolRotate any STL/OBJ/GLB 180° around the X axis to fix upside-down imports. Common when bringing CAD into print slicers. Browser-based.
Open toolTest 6 canonical orientations and rank by support area, footprint, and overhang. Find the print-friendly pose without manual rotation. Browser-based.
Open toolAuto-scale STL/OBJ/GLB models to fit any printer bed (X/Y/Z mm). Maintains proportions. Browser-based, no upload.
Open toolPNG thumbnails, 3D text-to-STL, QR code-to-STL, and per-layer cross-section slicing.
Render PNG previews of STL/OBJ/GLB files for galleries, README docs, and product pages. WebGL renderer, browser-based, no upload.
Open toolType any text and get a printable STL with extruded letterforms. Adjustable font size and depth. Perfect for nameplates, signs, and labels. Browser-based.
Open toolType a URL or text and get a printable STL of a 3D QR code. Each module becomes a raised cell. Tactile, scannable, perfect for product packaging.
Open toolExtract a 2D cross-section of any STL/OBJ/GLB at a specified Z height. SVG output. Useful for engineering drawings and laser cutting layouts.
Open toolMulti-file mesh merging and G-code toolpath visualisation.
Combine two or more STL/OBJ/GLB files into a single watertight mesh. Useful for multi-part prints, assembly previews, and chimera models.
Open toolDrop a G-code file and see the toolpath rendered to PNG. Identify travel moves, layer transitions, and infill patterns at a glance. Browser-based.
Open toolSee which tools to chain together for 3D printing prep, AR asset authoring, CAD pipeline cleanup, and mesh optimisation workflows.
