Image to STL Converter

Turn a photo, logo or drawing into an STL file. Choose a raised relief for flat artwork, or a full 3D object for a model you can view from every side.

Make a raised surface from image brightness, with a solid rectangular base. Upload an image or try the Quady sample.

Image-to-STL examples

Compare each source image with its STL. Load a result to rotate it, or download the file.

Quady logo relief

80 × 80 mm · 2.5 mm relief · 2 mm base

STL result

The Quady logo on an 80 mm square plaque. Try the sample above to adjust size and depth.

STL result

This character was generated from the shown image, then converted to STL. Inspect the cape, shield and hidden surfaces before printing.

Download this STL Use this image

STL contains shape, without colors or textures. Check these files in your slicer before printing.

Convert image to STL in three steps

1. Choose your result

Use Raised relief for a plaque or embossed picture. Choose Full 3D object for a figurine, sculpture or prop with depth on every side.

2. Add a clear image

For relief, use strong contrast and adjust depth, base thickness and size. For a full object, show the whole subject against a simple background, then select a generation model.

3. Preview and download

Rotate the result, confirm its dimensions and export STL. Open the file in your slicer to check layers, supports and small details before printing.

Get a cleaner result from your image

For a raised relief

Lighter areas rise higher by default. Invert depth to swap raised and recessed areas. Use a tightly cropped image with clear shapes and strong contrast.

For a photo intended to be lit from behind, explore image to lithophane.

For a complete 3D object

Use one centered subject with a clear outline. Image-to-3D AI estimates the unseen sides; a photo does not supply exact dimensions or a verified printable shell.

Not the result you expected?

The model looks flat

A relief is a picture raised on a backing plate. For a figurine with a back and sides, choose Full 3D object above. AI estimates the parts your image does not show.

The surface looks rough

Photo grain and sharp brightness changes become bumps. Crop closer, start with a cleaner image and reduce relief depth. Simplify tiny details that disappear in the preview.

The background becomes a plate

Relief keeps a rectangular base, even for transparent PNGs. For a logo with an open outline, use logo to STL instead.

From image to 3D print: final checks

An STL preview shows the shape. Your slicer determines how that shape will print.

Size and thickness

Confirm millimeter dimensions and the thinnest areas. Small features may need thickening for your printer and material.

Holes and loose parts

Look for holes, separate pieces and overlapping surfaces. Repair them in a slicer or 3D editor before printing; downloading STL does not repair the model.

Layers and supports

Choose a stable orientation and inspect layer previews for missing details, overhangs and contact with the print bed.

For the next steps, follow the AI 3D printing guide.

Image to STL questions

How does photo to STL conversion work?

A relief turns image brightness into height on a rectangular base. For a figurine or another complete object, choose Full 3D object: AI generates the mesh first, then you prepare its STL. Hidden sides are inferred and may need editing.

Is the image to STL converter free?

Raised relief conversion, preview and STL download run in your browser without an account or generation credits. Full 3D object generation uses credits; check the selected model's cost in the workspace before generating.

Which image formats can I use?

Picture to STL conversion accepts PNG, JPG, JPEG and WebP images up to 8 MB for reliefs. Clear shapes and strong contrast work best. For AI generation, follow the image requirements shown by your selected model.

Will the STL keep the image's colors or textures?

No. This STL export contains geometry, not image colors or textures. Relief height comes from brightness. Keep the original GLB if you also need the textured AI model.

How do I set the size for 3D printing?

For a relief, set width, relief depth and base thickness in millimeters before downloading. The height follows the image's proportions. STL does not store a unit label, so confirm the dimensions in your slicer. The Full 3D object workspace has separate print-size controls.

Does an STL download guarantee a successful print?

No. Check closed surfaces, wall thickness, overhangs and contact with the print bed. Open the file in your slicer and inspect its layers before printing. AI-generated objects can require mesh repair or thicker small parts.
