What problem this product solves MeshCrunch helps teams reduce heavy 3D assets before they reach games, websites, XR applications, and other real-time renderers. Large polygon counts can increase load times and make assets harder to ship. MeshCrunch reduces triangle counts while preserving the model silhouette, creates level-of-detail chains, and converts supported 3D files into more usable formats. Key features and benefits The Studio workspace lets you upload a model, inspect it, choose an optimization operation, compare the result with the original, and download the output. Mesh simplification uses quadric-error decimation and reports triangle and file-size savings. LOD generation creates multiple detail levels from one high-poly asset, with individual downloads or a ZIP containing a manifest. Watertight Rebuild can create a closed surface around models with holes, self-intersections, or loose triangles, though it removes materials, textures, and UVs. Additional browser-based tools include mesh inspection for non-manifold edges, holes, winding, missing UVs, and platform suitability; a 3D viewer with orbit, grid, and wireframe controls; and a GIF Maker for turntable GIF or MP4 exports. The converter supports OBJ, STL, PLY, OFF, GLB, and glTF. Uploads can be up to 50 MB per file, storage is private, and files remain owned by the uploader. Notable alternatives and comparison General-purpose 3D modeling, mesh conversion, and optimization tools can provide overlapping capabilities. MeshCrunch is more focused on a streamlined asset-preparation workflow, combining simplification, LOD creation, inspection, conversion, watertight rebuilding, and preview exports in one toolkit. Its Studio is visual, while MeshCrunch MCP supports agent-based workflows with AI clients such as Claude on Starter and Pro plans. Pricing models and plans MeshCrunch uses processing credits for server-based operations including simplification, LOD generation, watertight rebuilding, and conversion. Simplification and watertight operations start at 1 processing credit, while LOD generation starts at 1 credit per level. Browser-based inspection, viewing, and GIF or MP4 creation do not use credits. A free tier is available with no account required to start. The first conversion requires no account. Free-account files are kept for 7 days, while files created without an account are deleted after 24 hours unless claimed by signing in. Starter and Pro plans include MCP access. Specific plan prices are not shown in the provided homepage content. FAQs Q: Which file formats does MeshCrunch support? A: MeshCrunch parses OBJ, STL, PLY, OFF, GLB, and glTF files, with supported input and output varying by operation. Q: Does MeshCrunch work in the browser? A: Yes. Mesh inspection, the 3D viewer, and GIF or MP4 creation run in the browser. Optimization operations are processed on MeshCrunch servers. Q: Can MeshCrunch create LOD assets? A: Yes. It generates a complete LOD chain from o
