Warm-cool temperature

The temperature slider shifts the image along the blue-orange axis: drag right to warm it up (more red, less blue), or left to cool it down. Centered means no change.

Green-magenta tint

The tint slider corrects the second white-balance axis — push toward magenta to neutralize a green cast from fluorescent light, or toward green to cancel a magenta cast.

How to adjust color temperature

1

Upload your image

Drag and drop or click to select a JPG, PNG, or WebP image.

2

Set the temperature

Drag the temperature slider right to warm the photo or left to cool it. The center is neutral, so the image is unchanged at rest.

Correct the tint

Use the tint slider to remove a green or magenta cast left by artificial lighting.

Download

Choose PNG to keep transparency or JPG for a smaller file, then download the balanced image.

Frequently asked questions

What does color temperature do to a photo?

Color temperature controls how warm (orange) or cool (blue) an image looks. Warming adds red and reduces blue, which makes a photo feel sunnier; cooling does the opposite. It's the main control for fixing white balance.

What is the tint slider for?

Tint adjusts the green-magenta axis of white balance. Fluorescent and mixed lighting often leave a green or magenta cast that the temperature slider alone can't fix — tint neutralizes it.

Is this color temperature tool free?

Yes — completely free and unlimited. No signup, no account, no watermark, and no daily limit.

Are my files uploaded to a server?

No. All adjustments happen in your browser on your device. Your image never leaves your computer, so it stays fully private.
