3D File Converter and Mesh Tools

Convert, inspect and measure OBJ, STL and STEP models locally. Choose a workflow below; model files stay on your device and no account is required.

OBJ to STL

Convert your OBJ model into an STL file, right in your browser.

STL to OBJ

Turn an STL mesh into an OBJ model for your next project.

STEP to OBJ

Bring CAD geometry into your mesh workflow.

STEP to STL

Convert CAD surfaces into an STL mesh with adjustable precision.

OBJ to GLB

Package an OBJ mesh into a compact, shareable GLB file.

STEP to GLB

Make CAD models ready for a 3D web viewer.

STL to STEP

Wrap your triangle mesh in a faceted STEP surface model.

3D viewer

Open, orbit and explore your model without installing CAD software.

Resize & rotate

Set the right dimensions, units and orientation before exporting.

Simplify mesh

Reduce mesh complexity and preview the result before downloading.

Inspect mesh

Check open boundaries, non-manifold edges and triangle quality.

Measure

Pick two points on a model to measure their distance.

Export parts

Choose individual parts or split disconnected mesh components.

Capture image

Save a model view as a PNG, with an optional transparent background.

Batch convert

Convert a queue of models locally and download the results as a ZIP.

Which formats can I use?

Open OBJ, STL and STEP/STP files. Conversion tools export OBJ, STL, GLB or faceted STEP, depending on the workflow. Materials, CAD features and units have format-specific limitations explained on each tool page.
