01 / Choose a workflow
Remesh vs decimate: choose the right operation
Compare remeshing and decimation for scans, sculpting, game assets, and printing. Learn what changes, what can be lost, and how to check a result.
Mesh guides
Mesh cleanup and remeshing guides
File too large, model missing from the preview, or holes after reduction? Start with the guide for that problem. For scans and AI-generated models, follow the cleanup steps before changing the polygon count.
Ready to try a remesh?
Open a copy in the browser remesher. It exports geometry-only OBJ, so keep your original textures and materials. Check the result for missing faces before using it in another application.

02 / Solve a problem
Mesh remeshing problems: find the failing step
Diagnose mesh files that will not open, missing previews, processing errors, and broken output. Follow separate checks for the browser tool and Blender.
03 / Solve a problem
Reduce STL file size: encoding first, geometry second
Reduce STL file size by checking ASCII versus binary encoding, removing unwanted geometry, and testing decimation while protecting dimensions and detail.
04 / Prepare an asset
3D scan mesh cleanup: remove defects before reducing detail
Clean a 3D scan by removing background fragments and checking holes and normals. Keep the original textures and verify the scan's scale before reducing detail.
05 / Prepare an asset
AI-generated mesh cleanup: keep shape, check structure
Inspect an AI-generated 3D model, clean disconnected geometry, plan UV and texture transfer, and validate a lighter mesh before exporting to your next tool.
06 / Prepare an asset
Remesh for 3D printing without skipping validation
Learn when to remesh for 3D printing and how to check dimensions, holes, wall thickness, and sliced layers. Understand why fewer faces do not mean print-ready.
A useful order for checking a mesh
- Choose the destination. A static scene, animated asset, and physical print need different checks. Decide which details and data must survive before changing geometry.
- Inspect the source. Confirm its format, dimensions, visible parts, and texture dependencies. Keep an untouched copy so a failed cleanup can be discarded.
- Change one thing at a time. Try a conservative operation, inspect the surface, and record the settings. Avoid stacking several destructive passes before checking the first result.
- Reopen the actual export. A preview is useful, but the downstream application must be able to read the saved file. Check materials, dimensions, and geometry again there.
Using the browser tool
You can open OBJ, STL, ASCII PLY, and OFF files below 25 MB. Start with the tutorial for import and export steps, or check the settings reference for face targets and preservation options. For texture baking, hole repair, rigging, or STL export, continue in Blender or another desktop modeling tool.
