How it works

1
Drop a black & white photo
Select a JPEG, PNG or WebP image. The file is processed entirely in your browser — nothing is uploaded.
2
Choose a colorization style
Artistic mode produces vivid, stylized tones. Realistic mode generates natural, photography-like colors faithful to the original scene.
3
AI colorization in your browser
The DDColor deep learning model runs via ONNX Runtime Web — no GPU server needed. First run requires a one-time model download stored locally.
4
Download
Save the colorized image as a full-resolution PNG. Revisit the page and the model is already cached — no re-download.

Frequently Asked Questions

Is the Image Colorizer free?

Yes, completely free. The AI model runs locally — no server, no API key.

Is my photo sent to a server?

No. The DDColor model runs via ONNX Runtime Web directly in your browser — your image never leaves your device.

What is the difference between Artistic and Realistic modes?

Artistic mode produces vivid, stylized colors. Realistic mode generates natural tones that look like an authentic period photograph.

Why is the first run slower?

The DDColor model (~100 MB) is downloaded once and stored in your browser's IndexedDB. All subsequent uses run instantly from cache.
