STL Converter tools

Choose a workflow by the file you have, the output you need, or the mesh problem you want to inspect.

CAD and mesh to printable geometry

• OBJ to STL converter — convert polygon meshes for printing.
• 3MF to STL converter — extract model geometry from a slicer package.
• STEP to STL converter — tessellate CAD solids with deflection controls.
• GLB to STL converter — turn web scenes into static geometry.
• FBX to STL converter — export supported scene meshes for printing.
• Batch ZIP to STL converter — process supported files in one archive.

Images and vectors to reliefs or extrusions

• PNG to 3D relief — use grayscale or alpha-mask input.
• JPG to relief STL — map image brightness to height.
• SVG to STL extrusion — turn supported paths into solids.
• DXF polyline to STL — extrude supported closed outlines.

Export an existing STL

• STL to OBJ for Blender — export editable mesh geometry.
• STL to GLB for Web and AR — package geometry for real-time viewers.
• STL to FBX for Unity and Maya — create a static FBX scene.
• STL to faceted STEP — hand off triangle geometry to CAD tools.

Inspect and integrate

• Online STL Viewer — preview STL files and inspect the mesh.
• STL open edge and normal checker — check a file before printing.
• Repair STL holes and open edges — inspect topology before slicing.
• STL Converter API documentation — create jobs and download results.
• STL and mesh FAQ — read common conversion answers.
