Image to STL is an AI-powered online tool that converts 2D images into 3D printable models, exporting to STL, GLB, and OBJ formats. It turns photos, sketches, or text descriptions into high-quality 3D meshes with accurate geometry, supporting up to 1,500,000 triangles in Pro mode.
What is Image to STL?
Image to STL is a web-based platform that uses AI to transform image inputs (JPG, PNG, WebP, 128–5000 px, max 5 MB) into 3D models. It also accepts text prompts for text-to-3D generation and multi-view images for more accurate results. The tool runs entirely in the browser, requires no software installation, and is developed by the team at imagetostl.io.
Key Features
- AI-Powered Conversion — Generates 3D meshes from single or multi-view images with accurate geometry, processing in minutes.
- Multiple Export Formats — Download models as STL (3D printing), GLB (WebXR, game engines), or OBJ (general 3D applications).
- Quality Options — Standard mode (80K triangles) for fast draft; Pro mode (up to 1500K triangles) for detailed printing; Max mode for highest fidelity.
- Multi-View Support — Upload front, left, right, and back views to improve model accuracy.
- PBR Materials — Generated models include physically-based rendering materials for realistic lighting and textures.
- Free Tier — 15 monthly credits, 1 concurrent task, limited downloads, CC BY 4.0 licensing.
- Paid Plans — Pro ($16.9/month, 500 credits) and Max ($26.9/month, 1000 credits) offer unlimited downloads, private assets, and creative styles (scale figure, bust, badge).
- Credit Packages — Purchase additional credits: 200 for $9.9, 400 for $16.9, 800 for $29.9, 1000 for $36.9.
Who is it for?
- 3D printing enthusiasts — Turn personal photos or designs into printable STL files without modeling skills.
- Game developers — Generate game-ready assets quickly; export in GLB for Unity or Unreal.
- Product designers — Create 3D product previews or concepts from photos for client presentations.
- AR/VR developers — Build immersive experiences with optimized models that load fast on mobile and web.
What can you do with Image to STL?
- Create custom figurines — Upload a character or portrait image and generate a 3D model suitable for 3D printing as a scale figure or bust.
- Turn sketches into architectural models — Use the multi-view feature to convert building sketches into 3D models for early-stage design reviews.
- Generate e-commerce product views — Convert product photos into interactive 360° 3D models to boost online conversions (reported 23% increase).
How does Image to STL work?
- Upload an image (JPG, PNG, WebP) or describe a subject with text. Optionally provide multiple angles for better results.
- AI processes the input and generates a 3D mesh. Choose between Standard (80K triangles) or Pro (1500K triangles) quality.
- Preview the model in an interactive 3D viewer — rotate, zoom, and inspect every angle. Regenerate if needed.
- Download the final model in STL, GLB, or OBJ format, ready for printing or digital use.
Pricing
The tool offers a free tier with 15 monthly credits, 1 concurrent task, and limited downloads. Paid plans start at $16.9/month (Pro) with 500 credits, 2 concurrent tasks, and unlimited downloads. The Max plan at $26.9/month provides 1000 credits and 3 concurrent tasks. Credit packages are also available separately. All paid plans include private asset ownership and priority queue.
FAQ
Is Image to STL free?
Yes, there is a free plan that includes 15 monthly credits, one concurrent task, and limited downloads. Generated assets use a CC BY 4.0 license.
You can download models in STL, GLB, and OBJ formats. GLB is recommended for WebXR and game engines, STL for 3D printing.
How long does generation take?
Most conversions complete in minutes, depending on quality mode and current server load. Pro mode takes slightly longer than Standard.
Can I use the models commercially?
On the free plan, assets are licensed under CC BY 4.0 (requires attribution). Paid plans grant you full ownership with no attribution needed.
What is the difference between Standard and Pro quality?
Standard mode generates 80,000 triangles for fast previews; Pro mode uses up to 1,500,000 triangles for detailed, printable models.
