Bring History to Life: Free AI Photo Colorizer

Our photo colorizer gives black and white photos a warm, vintage hand-tinted look: upload your image and a fast tone-mapping effect adds colour in about a second. Our free tool runs entirely in your browser, so old family photos never leave your device. Seeing the past in color makes it feel closer, more real.

How Does It Work?

It is a tone map, not a neural network. The tool measures the luminance (brightness) of every pixel and tints it by range: shadows get a slightly cool tint, midtones a warm sepia-to-skin tint, and highlights a soft warm neutral. The result reads like a hand-tinted vintage print. Because the colour follows brightness rather than content, it will not turn a sky blue or grass green; deep-learning colorizers that guess real colours need model downloads of 100 MB or more, which this tool avoids.

How to Colorize Your Photos

1. Digitize: If you have a physical print, scan it or take a high-quality photo of it with your phone.
2. Open the Tool: Go to the AI Colorizer Page.
3. Upload: Drop your image file.
4. Colour it: Press Add colour. If you want the tint stronger or softer, adjust saturation afterwards in the HSL adjust tool.
5. Save: Download your restored masterpiece.

Preservation Tips

After colorizing, we recommend keeping both the original digital scan and the new color version. The tint is an artistic effect, not a recovery of the real colours, so preserving the historical original is important for archival purposes.
