MeshRefinery is a browser-based toolbox for identifying holes, open edges, non-manifold geometry, floating fragments, and other problems in 3D meshes. Its free local tools can repair common issues and convert between formats without uploading the source file.
Credit-based options add deep watertight reconstruction with color handling and image-to-3D generation. The service is intended for 3D printing, game assets, and AR or VR pipelines.

How to use this tool
Drop an STL, OBJ, GLB, glTF, or 3MF file into the browser tool and read the free diagnosis before changing the model.
Use free repair for a watertight geometry rebuild or local conversion when color transfer and AI reconstruction are unnecessary.
Rotate and inspect the repaired preview, checking holes, shells, scale, orientation, color, and thin geometry.
Choose deep repair when approximate GLB surface color must be transferred, or image-to-3D when creating a new model from a reference image.
Download the result in the required format and validate it again in the target slicer, game engine, AR viewer, or 3D application.
Core Features
✓Instant diagnosis of open edges, non-manifold geometry, floating shells, and degenerate faces.
✓Free watertight repair for holes and floating debris.
✓Deep repair that can transfer approximate surface color from self-contained GLB files.
✓Local conversion among STL, OBJ, GLB, glTF, and 3MF formats.
✓Color-preserving GLB-to-3MF conversion for compatible files.
✓WebAssembly processing that keeps core repair and conversion inside the browser tab.

Frequently Asked Questions
MeshRefinery is a browser toolbox for diagnosing, repairing, converting, previewing, and generating 3D mesh files.
The official site lists STL, OBJ, GLB, glTF, and 3MF.
Core diagnosis, local repair, conversion, and preview tools are free and require no signup for single files.
Core parsing, repair, and conversion run locally through WebAssembly, so those files do not leave the browser tab. Server-based deep repair or generation follows its own processing terms.
It targets non-manifold edges, holes, and floating fragments to create watertight geometry, but it can drop color.
Deep repair is a credit-based rebuild that can transfer approximate surface color from a self-contained GLB into vertex colors.
The official page currently lists 20 credits for deep repair and 30 credits for image-to-3D generation.
Starter is $9.90 monthly or an annual equivalent of $7.92 per month, with 1,800 annual credits.
Pro is $19.90 monthly and Studio is $49.90 monthly; annual equivalents are $15.92 and $39.92 per month.
The paid subscriptions list commercial use for generated models, subject to source-image and account terms.
