How it works

How to convert a logo to STL

The logo to STL converter gives a clear icon, silhouette or brand mark uniform depth, creating a solid model for a 3D-printing or modeling workflow. Conversion happens locally in your browser.

  1. 1
    Choose your logo

    Upload a PNG or JPG up to 20 MB and 4096 × 4096 pixels.

  2. 2
    Check the extrusion

    Adjust Depth and Size while inspecting the 3D preview.

  3. 3
    Download the STL

    Save the binary STL for your slicer or modeling workflow.

Source artwork

Transparent vs solid-background logos

A transparent PNG is the cleanest source because its alpha channel directly defines the shape to extrude. Transparent pixels remain outside the solid rather than becoming a background plate.

A high-contrast opaque PNG or JPG can also work when it has a simple light background. In that case, threshold separation identifies the darker foreground. IntoSTL does not remove backgrounds, clean artwork with AI or rebuild the logo as vector geometry.

What logos work best for STL extrusion?

Simple, high-contrast marks with bold connected shapes usually make the most dependable 3D logo STL. Supported holes and counters may remain open when the source has clean, closed contours.

Very thin strokes, small counters and isolated details can be difficult to print or may not survive at a small final size. Inspect both the browser preview and the downloaded STL in your slicer.

For general transparency and relief guidance, see PNG to STL. For photographs and other non-logo images, use the broader Image to STL guide.

Common questions

Logo to STL FAQ

Do transparent logos work best?

Transparent PNG logos usually give the clearest result because the alpha channel defines the foreground directly.

Can holes inside a logo stay open?

Supported holes can stay open when the artwork defines clean, closed contours, but complex details may not convert perfectly.

What happens if my logo has a solid background?

A simple light background helps the tool identify the foreground. It does not remove or reconstruct backgrounds.

What logo details may be too thin to print?

Very narrow strokes, tiny counters and isolated details can become fragile or disappear at practical print sizes. Check the preview and slicer before printing.
