How to Colorize a Black and White Photo with AI
- Upload the black and white photo you want to colorize
- Click Colorize and let the AI model run in your browser (first run downloads a ~61 MB model, then it's cached)
- Wait about 11 seconds while DeOldify predicts natural colors for your photo
- Adjust colour intensity and colour temperature until it looks right, then download
Why Colorize Old Photos with AI
What makes this different
- Uses DeOldify, a real GAN colorization neural network, not a preset color filter
- Runs 100% in your browser via ONNX Runtime Web โ your photo never touches a server
- Keeps your photo's original resolution; only color is added, so detail stays sharp
- No account, no credit limits, no watermark on the result
Current limits, stated honestly
- The AI model is about 61 MB and downloads once on first use, then cached by your browser
- First colorization takes about 11 seconds total, including that one-time download
- Colors are chosen automatically by the AI; there's no color picker, region selection, or brush to guide specific colors
Frequently Asked Questions
Is this photo colorizer really powered by AI?โผ
Yes. It runs DeOldify, a genuine GAN colorization neural network, using ONNX Runtime Web. It is not a preset sepia or tint filter.
Is my photo uploaded to a server?โผ
No. The AI model runs entirely inside your browser. Your photo is processed on your device and never leaves it, which matters most for family and wedding photos.
Can I choose specific colors for parts of the photo?โผ
No. The AI predicts colors automatically across the whole photo. You can only adjust overall colour intensity and colour temperature (warm or cool) โ there's no color picker, region selection, or brush.
Does colorizing reduce my photo's resolution?โผ
No. The model predicts color at a small internal size, but your original brightness detail is preserved and only the color is applied on top, so a 400ร300 photo stays 400ร300.
How long does it take?โผ
About 11 seconds end to end the first time, including the one-time ~61 MB model download. After that, the model is cached and later colorizations start immediately.
Is it free? Do I need an account?โผ
Yes, completely free, no signup, and no watermark on the result.
