About Photo Colorizer
Bring old family photos to life. An AI model trained on millions of pictures recognises faces, skies, trees, clothes and buildings and gives them natural colours — running in your browser, so treasured photos never leave your device.
The colours are laid over the original photo’s own light and shade at full resolution, so every detail stays sharp. Make the colours stronger or subtler, warmer or cooler, compare before and after, and colour a whole album at once.
Good for
- Colouring old family and wedding photos
- Historical pictures for presentations and books
- Black-and-white scans for gifts and prints
Tip: Clean up and enhance a scan first (Photo Enhancer), then colorize it.
Frequently asked questions
How does the AI know the colours?
The DDColor model learned from millions of colour photos which colours usually belong to skies, skin, plants, clothes and buildings, and predicts the most likely colours for your picture.
Is detail lost?
No. Only the colour comes from the AI; the light and shade of every pixel come from your original photo, at full resolution.
Why is the first run slow?
The AI model (113 MB) is downloaded once. After that it starts at once, even offline.
Are my pictures uploaded to a server?
No. The AI runs in your browser on your own device. Only the AI model itself is downloaded the first time; your pictures never leave your device.
Are the colours historically accurate?
Not necessarily. The AI picks plausible colours from what it has learned, so clothes, cars or walls may come out in colours they never had.
