Browser-based mesh tools, nothing to install

Every tool here runs entirely in your browser — your file never leaves your device. Fix, convert, scale or lighten a model, then send it straight to the pricer for a quote.

Convert & repair

Turn STEP, IGES, 3MF or OBJ into a print-ready STL, and diagnose broken or non-manifold meshes before they cost you a failed print.

Scale & simplify

Resize with independent X, Y and Z or by percentage, and cut the triangle count of heavy scans so they slice cleanly.
