No, images never leave your device for free modes. All processing is done locally.

Which image formats can I convert to STL?

You can convert PNG, JPG, WebP, SVG, GIF, and BMP formats.

Is the exported STL watertight and printable?

Yes, the generated STL files are closed, manifold meshes that are suitable for 3D printing.

What is a lithophane?

A lithophane is a 3D printed panel that varies in thickness based on photo brightness, creating an image when backlit.

The basic image to STL conversion is free, with no hidden costs. For advanced features like AI Full 3D, there are paid options available starting from $9.99 for a small pack of generations.

1. The tool excels in providing a fast and user-friendly interface for converting images to STL files, making it accessible for both beginners and experienced makers.
2. The in-browser processing ensures privacy and security, which is a significant advantage over other online converters.
3. However, the lack of advanced features in the free version may limit users looking for more complex 3D modeling options.
4. While the basic conversion modes are effective, users seeking high-quality, detailed 3D models may need to explore the paid AI Full 3D option.
5. Overall, ImageToSTL.online is a practical solution for quick and straightforward image-to-STL conversions, but it may not meet the needs of users requiring intricate designs.
