How to Colorize a Photo Online
This tool adds color to black and white photos or restores faded, washed-out colors entirely inside your browser — the image never leaves your device, so it stays completely private. Just drag and drop a JPG, PNG or WebP file into the area above and choose between two modes. Colorize B&W Photo converts the picture to grayscale and tints it with the color you pick, mapping dark pixels to dark shades and bright pixels to light shades of that tone — a classic duotone effect that brings old portraits and scanned family photos back to life. Boost Colors increases the saturation of dull or faded images so they look vivid again. The preview updates instantly while you drag the strength slider, so you can fine-tune the result before downloading it as a high-quality PNG. No signup, no watermark, no file size limits.
