About DOT‑O‑MATIC

What is DOT‑O‑MATIC?

DOT‑O‑MATIC is a free, web-based SVG stipple generator that transforms your images into beautiful, scalable vector dot art. Perfect for artists, designers, and makers who want to create precision stipple artwork for posters, CNC machining, laser cutting, engraving, or print projects.

Key Features

• 100% Client-Side Processing: All image processing happens in your browser. Your images never leave your device, ensuring complete privacy.
• Scalable Vector Output: Generates clean SVG files that can be scaled to any size without quality loss.
• Precise Unit Control: Output uses real-world units (inches or millimeters) that match your final output size.
• Non-Overlapping Dots: Advanced algorithm ensures dots never overlap, creating clean, professional results.
• Voronoi Optimization: Uses Lloyd (centroidal Voronoi) relaxation to evenly distribute dots while respecting image brightness.
• Customizable Appearance: Control dot sizes, colors, shapes, and placement options to match your vision.
• Multiple Color Modes: Single color, source image colors, or grayscale from brightness.
• Grid Alignment: Optional grid-based placement for uniform, structured patterns.

Use Cases

DOT‑O‑MATIC is ideal for:

• Art & Design: Create stipple art illustrations, posters, and artwork
• CNC & Laser Cutting: Generate precise vector files for machining and engraving
• Print Projects: Produce high-quality halftone-style prints
• Educational: Learn about stippling techniques and algorithmic art
• Commercial Use: Create graphics for branding, packaging, or products

Privacy & Security

Your privacy is important to us. DOT‑O‑MATIC processes all images locally in your web browser using JavaScript. We never upload, store, or transmit your images to any server. This means:

• Your images remain completely private
• No server-side processing delays
• You can use the service even offline (after initial page load)
• No image storage or data collection

Technical Details

DOT‑O‑MATIC uses advanced algorithms including:

• Weighted Random Sampling: Places dots based on image darkness/brightness
• Spatial Grid Optimization: Efficient collision detection for non-overlapping dots
• Lloyd Relaxation: Iterative Voronoi centroid optimization for even distribution
• Gamma Correction: Adjustable size distribution curves for artistic control

Free & Open

DOT‑O‑MATIC is completely free to use. We support the service through advertising (Google AdSense). The tool runs entirely in your browser with no subscriptions, accounts, or hidden fees required.
