Colorize Black and White Photo
100% private — runs on your device, never uploaded. Works offline once loaded.
Bring colour to a black-and-white or faded sepia photo without sending it anywhere. A colourisation model, DDColor, runs inside your browser: it studies the scene — sky, skin, foliage, fabric, wood — and predicts plausible colours for each part. Only the colour is predicted; the photo's own lightness is kept at its full resolution, so every wrinkle, eyelash and thread of the original survives. Adjust the colour strength, compare before and after with a slider, and download the result. You can also repair dust and scratches and reduce grain in the same pass.
Frequently asked questions
Is my photo uploaded?
No. The colour model (about 130 MB) is downloaded from this site once and then runs on your own device. The photo never leaves your browser.
Are the colours accurate?
They are plausible, not known. A black-and-white photo does not record colour, so the model infers it from what things usually look like: skies tend to be blue and skin tones natural, but it cannot know the real colour of a particular dress, car or painted door. Treat the result as a well-informed guess, especially for historical or family records.
Does colourising lose detail?
No. The model works on colour only. Your photo's own lightness — which is where all the detail is — is kept at full resolution, and the predicted colour is blended in smoothly.
How long does it take?
The first time, the model has to download. After that a photo takes around ten seconds on a recent laptop, and longer on older or less powerful devices.
Can I colourise a photo that is already in colour?
You can, but it replaces the existing colours with the model's prediction. It is meant for black-and-white and faded sepia photos, and the tool tells you when a photo already has colour.
