Chromanga - AI Manga Colorizer

Transforming manga, one panel at a time. Click. Colorize. Read.

AI-powered manga colorizer that runs entirely in your browser. Colorize black-and-white manga pages instantly. CHROMANGA brings black-and-white manga to life with AI-powered cinematic grade colorization, entirely on your device, with zero server calls. How It Works: 1. Navigate to any major supported manga reader 2. Click the "Colorize" button in the extension on any manga 3. Watch as the AI transforms grayscale art into full color in seconds One Time Setup: This first initial run will generally take between 5 to 7 min because the CHROMANGA engine is auto calibrating. The engine is learning your hardware specs so it can deliver instant color for every chapter after that. All Features: 🎨 One-Click Colorization Click a single button to colorize individual panels or entire pages. Colorized images overlay the originals non-destructively so your reading experience stays smooth. 🔒 100% On-Device & Private All AI inference runs locally in your browser using ONNX Runtime Web (WebGPU or WASM). No images are uploaded. No server. No accounts. Your data stays yours. ⚡WebGPU Acceleration On supported browsers (Chrome 113+), Chromanga can leverage your GPU for significantly faster colorization. Falls back seamlessly to CPU-based WASM on older hardware. 🧹 Built-In Denoising Noisy scans? Chromanga auto-detects noise and applies edge-preserving bilateral filtering before colorization for cleaner results. Choose between bilateral, median, or Gaussian methods. 🎛️ Fine-Tune Your Results Adjust color saturation (0.5×–2.0×), post-colorization smoothing strength, denoising intensity, and processing quality all from the options page with real-time preview. 💾 Smart Caching Colorized images are cached locally so revisiting a chapter loads results instantly. Configurable cache size (50–1,000 entries) with automatic LRU eviction. 🌐 Support Works out of the box on popular manga readers, with sites supported by default. ➕ Add Any Site Click "Add This Site" in the popup to enable Chromanga on any manga reader not in the default list.
