Options
Per-channel multiplication
Each slider multiplies the corresponding channel by a percentage (0–200%). At 100% the channel is unchanged; below 100% suppresses it; above 100% boosts it — with automatic clamping to the 0–255 range.
100% private
Your image is processed entirely in your browser using the Canvas API — nothing is ever uploaded to a server.

Frequently asked questions
What does the RGB channel mixer do?
It multiplies the value of each color channel (red, green, or blue) in every pixel by the chosen percentage. Boosting a channel shifts the whole image toward that hue; cutting a channel pushes toward its complementary color.
Is the RGB tool free?
Yes — completely free and unlimited. No signup, no account, no watermark, no daily limit.
Are my files uploaded to a server?
No. The channel mixing happens entirely in your browser on your device. Your image never leaves your computer, so it stays fully private.
How is this different from hue rotate?
Hue rotation shifts all colors around the color wheel uniformly. RGB mixing boosts or suppresses individual channel intensities, which lets you create color casts, cross-process effects, and targeted channel corrections.
