Frequently Asked Questions
How does the photo colorization work?
The tool analyzes the brightness of each pixel in your black & white photo and applies color tints based on luminance ranges. Different brightness levels receive different colors — shadows get cool tones, mid-tones get earthy or green hues, and highlights get warm or sky-blue tints, creating a natural-looking colorized result.
Is my image uploaded to a server?
No. All processing happens entirely on your device using your browser's Canvas API. Your images never leave your device — nothing is uploaded or stored anywhere.
What are the different style presets?
Natural uses earth tones, greens, and blues for realistic outdoor scenes. Warm emphasizes oranges, yellows, and warm browns. Cool applies blues, teals, and cool grays. Vintage creates desaturated warm tones reminiscent of old photographs. Sepia produces the classic brown-toned effect of aged photos.
Can I adjust the color intensity?
Yes. Use the intensity slider to control how much color is applied, from 0% (fully grayscale) to 100% (maximum colorization). A value around 60-80% typically produces the most natural results.
