What is AI Image Colorizer?

This tool adds color to grayscale and sepia photos. The model looks at what is in the frame (faces, hair, clothes, buildings, plants, sky) and chooses tones that fit both the object and the period, while every face and detail stays where it was.Its choices are informed guesses. When you know a real color, such as the paint on a front door or a favorite dress, write it in and the model uses it. For prints with scratches or tears, use the photo restorer first.

How to use Image Colorizer

Three steps from an idea to a finished result.

11. Upload the grayscale or sepia photo
22. Add the colors you know, or leave the choice to the model
33. Generate, then run it again with more hints if a color looks wrong

Tips for better results

Name the object and the color together: "the tram is green and cream", not just "green".
Fix damage before adding color. A scratch that has been colored in is harder to clean up later.
Look at skin tones first. They decide whether a colorized photo looks right, so compare two runs if they seem off.
For a large print, make the colored version bigger as the last step with the image upscaler.

Frequently asked questions

What people ask before they use Image Colorizer.

1How does it choose the colors?

From what it sees in the picture: skin, hair, fabric, leaves, sky and building materials, plus the era the photo seems to come from. Those are educated guesses, not a record of the real colors, so add what you know as hints.

2What are color hints?

Short notes on colors you are sure of, such as "the car was pale blue" or "grandma's dress was yellow". The model uses them for those things and picks the rest itself.

3Can it repair a damaged photo too?

It colors what is there. If the print is scratched or torn, run it through the photo restorer first and colorize the clean copy.

4Which model should I use?

Nano Banana is the default: quick, 60 credits per image and good at keeping faces as they were. Nano Banana Pro and GPT Image 2 are there when you want a second take on a tricky photo.

5How much does it cost?

One image on the model you pick. The Generate button shows the credits before you start, and a failed run is refunded automatically.

6Who can see the photos I upload?

Uploads stay in your account and go only to the model that colors the photo and to our safety check. Nothing appears publicly unless you share it.
