Free img2threejs converter Introduction

What is img2threejs?

img2threejs is a free online converter that transforms a single, clear object photograph into an editable, procedural Three.js model. It analyzes the image to rebuild the object as a structured 3D scene composed of named parts, materials, and transforms. Instead of delivering an opaque mesh, it provides human-readable TypeScript code and a JSON specification, making the result inspectable and fully modifiable within standard web development workflows.

Key Features of img2threejs

Interactive Browser Preview

Immediately visualize and orbit your generated 3D model directly in the browser. Toggle between material views and inspect the hierarchy of named parts.

Editable Procedural Output

The core value lies in editability. The converter creates a blueprint of named components (like "handle," "blade," or "wheel") built from procedural geometry. Every part, material, and transform is traceable and can be modified in the downloaded code.

TypeScript & JSON Export

Download the model as clean, typed Three.js TypeScript code that returns a reusable THREE.Group. The accompanying JSON specification details the construction plan, allowing for easy review, iteration, and integration into version control systems like Git.

Dual Generation Modes

  • Quick Mode: For single, clear reference images. Offers 1 free generation per day and is ideal for simple objects.

  • Agent Mode: A future multi-pass workflow designed for complex objects, utilizing multiple reference views for a more detailed reconstruction. This mode uses more computational resources and is not free.

How to Use img2threejs

  1. Prepare Your Image: Use a sharp, well-lit photograph of a single hard-surface object (e.g., a tool, appliance, or prop) against a simple background.

  2. Upload and Convert: Go to img2threejs.com/#converter, upload your PNG or JPG, and select "Quick Generate."

  3. Preview and Inspect: Once processed, interact with the 3D preview in your browser. Examine the scene graph to see the named parts.

  4. Download and Integrate: Download the editable TypeScript factory and JSON spec. Import the code into your Three.js project, where you can rename parts, adjust dimensions, change materials, or attach animations.

Pricing for img2threejs

  • Quick Mode: Includes ### 1 free anonymous generation per day.

  • Agent Mode: This advanced mode is not free. Jobs are priced in credits based on their estimated complexity (e.g., number of reference views, object detail). The cost is clearly displayed before you confirm the generation.

Helpful Tips for Using img2threejs

  • Ideal Subjects: Product photos, tools, kitchenware, mechanical parts, and furniture work best. The converter excels with objects that have clear silhouettes and distinct components.

  • Image Quality is Key: Ensure your subject is fully visible, well-lit, and has minimal occlusion. A clean background dramatically improves the analysis.

  • Understand the Limits: A single image cannot capture hidden surfaces. The back, underside, and internal connections are inferred. It is not suitable for organic shapes (humans, animals), hair, cloth, transparent materials, or photorealistic vehicle surfacing.

  • Prototype, Don't Finalize: Treat the output as a sophisticated first draft or interactive prototype—a structured starting point for web-based 3D—rather than a final, production-ready game asset or marketing model.

  • Leverage Named Parts: The semantic hierarchy is perfect for adding interactivity. You can easily attach click events or animations to specific named components like a "button" or "door."

Frequently Asked Questions

Is img2threejs free?

Quick mode includes 1 free generation per day. Agent mode, which uses significantly more AI and cloud resources for complex multi-view analysis, is a paid service.

What file formats can I export?

The primary exports are editable Three.js TypeScript code and a JSON build specification. It does not export traditional 3D file formats like GLB, OBJ, or FBX, as its focus is on code-first, web-integratable assets.

Can I edit the generated Three.js code?

Absolutely. The entire point is editability. You can rename parts, change materials, adjust transformations, add event listeners, or replace geometry. The JSON spec allows you to understand and modify the construction logic itself.

How does img2threejs differ from photogrammetry?

Photogrammetry recreates dense geometry and textures from many photos. img2threejs uses AI analysis and procedural generation from one primary image to create a structured, code-based model optimized for editability and browser integration, not millimeter-accurate surface reproduction.

Can I use the output commercially?

Yes, provided you have the rights to the original uploaded image and comply with the Terms of Service. You are responsible for ensuring the subject matter (e.g., a branded product) doesn't infringe on trademarks or other intellectual property.

Can the generated parts be animated?

The converter creates a named hierarchy ideal for later animation (e.g., rotating a wheel, opening a lid). However, it does not provide automatic rigging, skinning, or complex deformation animations. These require additional developer implementation using the exposed parts.

Is my image data private?

Uploaded images are processed through servers and AI models (like OpenRouter). While there is no permanent, account-linked library, service providers may process data under their own policies. Do not upload confidential, personal, or unlicensed imagery.

What is the best use case for img2threejs?

It is perfect for creating interactive product previews, game prop prototypes, creative coding experiments, technical explainers, and any web-based 3D project where maintaining an editable, component-based structure is more valuable than photographic mesh accuracy.
