About this tool
Warm up a cold photo or cool down one that is too yellow. The tool simulates changing the color of the light with a chromatic adaptation along the black-body curve, so whites shift naturally and the overall brightness stays the same.
The Tint slider corrects green or magenta casts, which are common under fluorescent and LED lighting.
- Works on your device. Nothing is uploaded.
- Free, with no sign-up and no watermark.
- No limits on file count or size beyond what your device can handle.
Questions and answers
What does the kelvin value mean?
It is the approximate light color the photo is shifted toward: lower numbers are warmer, like candlelight, and higher numbers are cooler, like shade on a sunny day.
How do I fix a yellow indoor photo?
Move Temperature to the left until white walls or paper look neutral, then use Tint if a green or pink cast remains.
