Vector API - Professional PNG to SVG Conversion

High-performance PNG to SVG vectorization API powered by VTracer (Rust) with AI-enhanced optimization for perfect shapes and colors.

Features

Rust-Powered Performance

  • VTracer Integration: O(n) algorithm vs traditional O(n²)
  • Lightning Fast: Handles gigapixel images efficiently
  • Memory Optimized: Processes large files without memory issues

Professional Quality

  • Perfect Shapes: Superior to Adobe Illustrator’s Image Trace
  • True Colors: Full color support with anti-aliasing resistance
  • Smooth Curves: Advanced spline and Bezier curve generation
  • Character Optimized: Specialized handling for cartoon/character art

Smart Optimization

  • Auto Cleanup: Removes unnecessary white backgrounds
  • Path Optimization: Simplifies coordinates for smaller file sizes
  • Layer Merging: Intelligent similar-color path consolidation
  • Size Reduction: Optimized output without quality loss

Flexible Methods

  • vtracer: High-quality mode with spline curves (recommended)
  • vtracer_fast: Fast mode with polygon approximation
  • ai_optimized: Custom AI-enhanced fallback method
  • character: Specialized for cartoon/character artwork
