Reduce an STL file size
Compress an STL by removing duplicate vertices, duplicate triangles, and degenerate faces; an optional precision value quantizes coordinates before Binary STL export.

Parameters at a glance
| Parameter | Value | Why it matters |
|---|---|---|
| Input format | .STL | Accepted source file extension. |
| Output format | STL | Geometry or archive produced by this route. |
| File size | Up to 250 MB | Upload guardrail before parsing or conversion. |
| Mesh review | Preview, normals, open edges | Check geometry before download or slicing. |
| Coordinate precision | default 1 (min 0.01, max 1, step 0.01) | Controls the generated geometry. |
Workflow and technical limits

- Upload a valid STL file.
- Review the generated mesh preview and diagnostics.
- Download the STL result and verify scale in the destination tool.
Frequently Asked Questions
Can I run reduce an stl file size online?
Yes. Upload a supported STL file, wait for the server operation to finish, then download the generated STL.
What does the STL result preserve?
The export preserves triangle geometry while dropping source-specific metadata such as materials, animation, or parametric history.
How should I validate the downloaded STL?
Open it in STL Checker or your slicer and confirm scale, face normals, open edges, and watertight status before manufacturing.
