Chromanga - AI Manga Colorizer
Extension Actions
- Live on Store
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).
📖 Auto-Colorize as You Read
After you colorize once, turn on auto-colorize and Chromanga will keep coloring new panels as you move through the chapter.
⚡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. The extension requests only the permissions it needs, when it needs them.
📤 Share to X
Colorize first, then open Share in the popup to pick a panel. Chromanga exports it as a PNG, saves it to your downloads, and opens X with a ready-to-post message so you can attach the image and share in seconds!
📱SPA-Aware
Fully compatible with single-page app navigation. Automatically re-detects images after route changes and handles lazy-loaded content.
Privacy:
Chromanga processes everything locally. No analytics, no tracking, no server communication. See our privacy policy for full details.

- Great, please add Russian localization according to coloring (objectively colors at random), more or less only paints dense drawing; this is not always the case, but these are more questions for the neural network that is used as models. fun to play, but objectively it colors sadly and most often it is better to read the original black and white work

- Never have I found a tool that was so accurate and instant. I'm a weeb and didn't know I wanted something like this for so long. Seeing JJK and DB Super become colorized actually got me so hype. Keep this up

- I use the Chromanga colorizer all the time when I read manga. I really like that we are able to adjust the settings for level of saturation. Its also surprisingly fast at colorizing, and it colorizes as I am reading. Great extension!

- Solid chrome extension. Really sets the vibe of the manga and is able to be mostly canon in colorization and atmosphere. This is really well done by most measures, and I can tell a lot of care has been put into it. I enjoy this extension and it makes manga reading easier and a better experience. Highly recommend to any manga readers out there.

- Wow, I’ve honestly been looking for something like this my whole life while reading manga. Being able to see the panels colorized makes such a huge difference. Fights and fast scenes are way easier to follow now instead of getting lost in all the motion lines and trying to figure out what’s happening. I’m genuinely amazed at how well this works. It feels like it adds a whole new level of clarity to the reading experience. Huge shoutout to the developer, this is an awesome app!
