Colorize black & white photos
Old family photos, brought to life in color. Free, unlimited, never uploaded.
This tool does not work in Safari. Its WebAssembly engine stops partway through the AI model. Open this page in Chrome, Edge or Firefox — they all work, including on a Mac. On iPhone, install one of those browsers from the App Store: iOS Safari and every iOS browser share the same engine. (135 MB)
Drop black & white photos here or click to browse
The AI model downloads once (~135 MB), then everything runs on your device. Photos are never uploaded.
Your family photos should not live on someone else's server
Most photo colorizers upload your image, process it in the cloud, and sell you the result back through credits or subscriptions. QuietPix ships the neural network to your browser instead. Your grandparents' wedding photo never leaves your device. The tool stays free because your hardware does the work.
Under the hood this is DDColor, a research-grade colorization model. It predicts the color channels for your photo while keeping the original brightness untouched, so every detail of the source scan survives. Drop a whole folder of scans and download them one by one, in full resolution.
Frequently asked questions
How does AI colorization work?
A neural network (DDColor) looks at the shapes and textures in your black and white photo and predicts realistic colors for them. It runs entirely on your device, so your photos are never uploaded. Your original brightness and detail are kept pixel-perfect; only color is added.
Is it really free and unlimited?
Yes. The AI runs on your hardware, so we have no per-photo costs. No credits, no watermark, no signup, no daily cap.
Why is the first photo slower than the rest?
The AI model (~135 MB) downloads to your browser once. After that it is cached, and every photo is processed locally. On computers with a modern GPU each photo takes a few seconds.
Are the colors historically accurate?
The AI predicts plausible colors from what it learned, not documented ones. Skin, sky, foliage and common materials usually look right. A specific car or dress may get a believable color that differs from the real one.
What photos work best?
Clear scans and digital black and white photos work best. Very small, blurry or heavily damaged photos get weaker colors. For old prints, scan at 300 DPI or photograph them flat in good light first.
