What Is the Photo Colorize Tool?

The Photo Colorize tool uses a deep learning model to add realistic colors to black-and-white photos automatically.

It is a great way to restore old family portraits and historical photographs. Everything runs locally in your browser.

How to Colorize a Photo

Follow these steps:

  • Drop or upload a black-and-white photo.
  • Wait for the AI model to download on first use.
  • Click Colorize Photo — the result appears in a few seconds.
  • Download the colorized image as a PNG file.

Tips

  • Clear, well-scanned grayscale photos give the best results.
  • The model works on any grayscale image, not just old photographs.
  • Combine with the Image Upscaler to enhance details afterwards.

Frequently Asked Questions

How does the AI colorization work?+
The tool runs a DeOldify-style neural network in your browser via WebAssembly. The model analyzes the grayscale image and predicts natural colors for every pixel.
Are the colors accurate?+
The AI makes its best guess based on common patterns it learned. Colors look natural, but may differ from the true historical colors of the scene.
Is my photo uploaded anywhere?+
No. The model and all processing run entirely in your browser — your photos never leave your device.
Why does it take a while the first time?+
The colorization model is about 60 MB and must be downloaded once to your browser. After that, subsequent images process much faster.
