Bring your black & white photos back to life. ColorBack uses on-device AI to add realistic, natural color to black and white photographs — old family photos, historical images, film scans, anything. One drop zone, one button, and a side-by-side before/after view. That's the whole app. Everything runs locally on your PC. Your photos never leave your machine — no uploads, no cloud, no account, no subscription. Just open the app, drop in a photo, and watch the color come back. HOW IT WORKS Drop or pick a black & white photo, press Colorize, and the built-in DDColor deep-learning model paints realistic colors directly onto your image. Compare before and after, then save the result as JPEG. WHO IT'S FOR Anyone restoring family albums, genealogy researchers, history enthusiasts, archivists, and anyone curious what their grandparents' world looked like in color. PRIVATE BY DESIGN 100% offline processing. No internet connection required after install. Your memories stay yours.
