GCODE → STL

Convert GCODE to STL

Convert GCODE files to STL in seconds. Geometry, UVs and materials are carried over where STL supports them, and the model lands the right way up.

How to convert GCODE to STL

  1. Add your GCODE file

    Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.

  2. Check the format is STL

    STL is already selected. You can switch to any other output from the menu.

  3. Convert and download

    Click Convert and your STL file is ready in seconds. Download it straight away.

What is GCODE?

G-code is the list of moves a 3D printer follows. Converting it rebuilds the printed strands as a mesh, so you can see or reuse a print when the original model is missing.

Full name
G-code toolpath
Type
Printer toolpath
Used in
3D printers, Cura, PrusaSlicer, Bambu Studio, OctoPrint
Strength
Recover a model from a print file.
Limits
The result is the printed strands, not the original smooth model.

What is STL?

STL describes a surface as a list of triangles, with no colour, material or unit information. It is the default file for 3D printing and is exported by almost every CAD and modelling program.

Full name
Stereolithography
Type
Triangle mesh
Used in
Cura, PrusaSlicer, Bambu Studio, Blender, Fusion 360, SolidWorks
Strength
Universal support in 3D printing software.
Limits
Only triangles: no colours, no materials, no units, no editable CAD features.

Good to know

G-code is a list of printer moves, not a model. We rebuild every extruded line as a thin strand, so the result looks like the actual print, layer lines included. It is useful for previewing a print or recovering a lost model, not for editing.

Questions

Can I get my original model back from G-code?

You get the printed shape, built from the extruded strands. Fine details are as accurate as the print itself, but the surface shows the layer lines.

Are materials and textures kept?

Colours and texture coordinates are carried over when STL supports them. STL does not store textures, so only the geometry carries over.

Will my model be upside down?

No. GCODE and STL may use different "up" directions, and we rotate the model so it stands the same way in your software.

Are my files uploaded?

No. The conversion runs inside your browser.
