Quady3D AI is an online tool that converts 2D images into 3D models. Users upload a single clear photograph, concept image, or illustration of an object and select an AI model to generate a textured 3D representation. The platform supports input formats including PNG, JPG, and WebP, and requires that the entire object be visible within the frame. The generated model can be rotated to inspect hidden sides, thin parts, and texture seams before downloading. The tool offers multiple AI model options, including TRELLIS.2 for textured drafts, and additional workflows for adjusting shape detail, face count, and texture resolution. Users can choose to generate a textured GLB or a first geometry draft with fewer settings and no texture. Controls are available for mesh layout, face count, and optional PBR (physically based rendering) materials. After generation, the model can be exported in formats such as GLB, STL, or OBJ. Common use cases include turning a single product image into a 3D model for reviewing form and materials, converting a character illustration into a textured 3D asset, and preparing a complete object geometry for 3D printing. The platform also provides guides for multi-view input when hidden sides matter, relief generation from image brightness, and a separate text to 3D model generator for scenarios where no reference image is available. The website includes a gallery of example inputs and their corresponding outputs for comparison.
