Bring black-and-white photos back to colour.

A colourisation AI studies the light and shapes in your photo and paints in natural colours — skies, skin, trees, water — while keeping every detail of the original.

How AI colourisation works

The editor uses DDColor, a modern colourisation network (Apache-2.0 licence) that downloads to your browser the first time you use it and then runs on your own device. It looks at the whole photo at once — recognising sky, skin, foliage, water, stone and fabric — and predicts the colour channels for each area. Those colours are then combined with your photo's original lightness at full resolution, so no sharpness or detail is lost.

A Colour intensity slider lets you go from a subtle, hand-tinted look to rich, vivid colour.

What to expect — honestly

  • Natural scenes look most convincing: skies, sunsets, water, grass, trees and skin tones.
  • Clothes, cars and painted objects are a guess. A black-and-white photo doesn't record what colour a dress or a door was, so the AI chooses a plausible colour. If you know the real colours, treat the result as a starting point.
  • Very damaged prints colourise better after restoration — use Restore Old Photos first, which can colourise as its final step.

Tips for the best result

  • Scan prints at 600 DPI or higher — see our guide to scanning and upscaling old photos.
  • Crop away scanner borders and white frames first so they don't pick up colour.
  • Lower the intensity slightly for portraits; skin looks more natural at 70–90%.
  • Finish with Auto Enhance or a gentle filter in the same editor.

FAQ

Colorize Photo questions

Is this photo colorizer really free?

Yes. There's no sign-up, watermark or limit. The AI runs in your browser, so there's no server cost per photo.

Are my photos uploaded?

No. The colourisation model downloads to your browser and runs on your device. Family photos never leave your computer or phone.

Are the colours historically accurate?

Not necessarily. Black-and-white photos don't store colour, so the AI predicts plausible colours. Natural things like sky and foliage are usually convincing; clothing and objects are educated guesses.

How long does it take?

The first use downloads the model (about 62 MB, then cached). After that, colourising a photo usually takes a few seconds.
