Clean Up OBJ 3D Scans Online
Clean up 3D-scanned OBJ files: remove isolated components, fill holes, smooth noisy surfaces, fix normals, and reduce polygon count.

Usually 5-30 seconds — depends on mesh complexity and selected operations.
Cleanup Operations
Remove Isolated Components
Removes disconnected mesh fragments. Useful for photogrammetry outputs that include background noise or scanner artifacts.
Fill Holes
Closes open boundaries in the mesh with surface-following triangulation.
Remove Degenerate Faces
Eliminates zero-area triangles that cause downstream processing errors.
Fix Normals
Recomputes normals for consistent outward orientation across the mesh.
Surface Smoothing
Taubin volume-preserving smoothing to reduce scan noise.
Polygon Reduction
Reduces face count while maintaining surface accuracy.
When to Use OBJ Scan Cleanup
Scan Post-Processing
Clean up OBJ exports from 3D scanning software before use in modeling tools.
CAD Import Preparation
Fix topology issues before importing scanned meshes into CAD software.
Blender/Maya Workflow
Quick cleanup of scanned OBJ meshes before manual editing in DCC tools.
Web 3D Publishing
Optimize scanned models for web viewers: smooth, decimate, and fix topology.
How It Works
Upload your OBJ file (with optional MTL and textures as a ZIP). The tool parses the mesh geometry, identifies scan artifacts, and applies your selected cleanup operations in optimal order.
The cleanup pipeline processes topology first (component removal, degenerate faces), then structural repairs (holes, normals), and finally geometry refinement (smoothing, decimation). Each step is independent and can be toggled on or off.
Limitations
MTL material references are preserved but UV coordinates may be reset during hole filling and smoothing. Multi-object OBJ files are merged into a single mesh. Self-intersecting geometry cannot be automatically fixed.
