Online Image Colorize Tool

Each RGB channel uses source × (1 − p/100) + tint × p/100, rounded to an 8-bit channel value. For source RGB(100,150,200), tint #3B82F6 = RGB(59,130,246), and p = 50, the result is RGB(80,140,223). At 0%, decoded RGB is unchanged; at 100%, RGB becomes the selected color. Alpha is preserved at every ratio, so transparency and the outline defined by alpha remain even at 100%; original RGB detail does not. This applies one uniform tint, without selecting objects or reconstructing the colors of a black-and-white photograph.

Processing takes place in this browser. The limit is 25 MiB per file and 24 million decoded pixels. The output is PNG with the decoded image dimensions and a filename based on the source name. Browser decoding and PNG export can alter RGB values in partially transparent pixels; fully transparent RGB is not reliable image information. Metadata is not preserved, and an animated input is processed as a decoded frame. Keep the original file.
