How it works
Drag the temperature slider
Move it right to add warmth by boosting red and cutting blue per pixel, or left to cool the shot by boosting blue and cutting red.
Download the result
Every change re-renders from the original pixels, so you can fine-tune freely, then export the final image as a PNG file.
FAQ
Is my photo uploaded to a server?
No. The image is decoded and processed entirely in your browser using the Canvas API. Nothing is ever sent over the network.
How does the warm-cool slider work?
Sliding right boosts the red channel and reduces blue for a warmer look; sliding left boosts blue and reduces red for a cooler look, applied to every pixel of the original image.
Can I undo my changes?
Yes. Every adjustment is recalculated from the original unedited pixels, so moving the slider back to zero restores the source photo exactly.
