画像をSTLに変換する方法

1

Upload an Image File

Open our Image to STL workspace and drag and drop your image into the upload area. We support popular formats including JPG, PNG, WEBP, BMP, TIFF and GIF. The maximum supported file size is 50MB.

2

Convert to STL

Click "Convert to STL" to turn your image into a 3D model. Our tool generates aligned geometry and clean meshes during conversion without requiring any technical knowledge or additional software.

3

Download Your Model

Once generation completes in seconds, click the download button to save your STL 3D model. Get a print-ready 3D model from a 2D image in seconds, not hours or even days.

Intricate geometry details

Preserve complex geometric structures during conversion with our AI technology. Experience breathtaking realism with intricate mesh details, ensuring your 3D models maintain the precision of their original 2D images.

よくある質問

Why use the Image to STL converter?
Our Image-to-STL converter is built for fast 3D workflows: upload an image, we generate a 3D model from it, and you export an STL file for your 3D printing workflow. Everything runs directly in your browser, with no installation required.
How many STL files can I convert at once?
You can convert one file at a time for free. For larger pipelines that need batch conversion and faster turnaround, those are available on our paid plans.
Is it safe to upload my image files to this converter?
Yes. Your files are processed securely and are not shared with third parties. Uploaded images are removed from our cache automatically, so your work stays private.
How long does it take to convert an image to STL?
Most image-to-STL conversions complete in seconds. The duration depends on the source image, the desired level of detail, and the complexity of the generated mesh. If it takes longer, try a clearer subject, a smaller file, or a simpler perspective.
Key considerations before converting an image to STL
Keep three things in mind. First, the image should have clear contours and as little distracting background as possible. Second, check the STL file in your slicer before printing — wall thickness, scale, and closed geometry. Third, STL does not preserve colors, materials, or textures; for colored 3D assets, formats like GLB are better suited.
How accurate is the image to STL converter?
Accuracy depends heavily on the source image. Clear contours, good lighting, and a clear perspective deliver better results. We interpret your 2D image as 3D geometry and export it as an STL file. Check the file before printing, especially for production-critical parts.
What should I check after converting to STL?
After download, check: 1. Does the STL file open in your slicer or 3D viewer? 2. Are scale and orientation correct? 3. Is the geometry watertight and 3D-print ready? 4. Are there missing faces, very thin areas, or unexpected artifacts?
Can I use the converted STL file with other tools?
Yes. Your STL works with standard slicers and 3D software like Cura, PrusaSlicer, Bambu Studio, and Blender. For surfaces, materials, or textures, choose a format like GLB depending on your target.
I am unable to convert my image to STL — what should I do?
If conversion fails, first check whether your image opens in another program. Shrink the file if it's too large, and upload a clear image with a recognizable main subject. If it still doesn't work, try PNG or JPEG as an alternative.
