This browser-based utility creates a black-and-white signature in PNG format. You can upload a digital signature of any color to the input and get back the same signature but now in black ink as the output. If the original signature has a transparent background, the program will keep its transparency and recolor only the opaque pixels of the signature. To recolor exactly the signature pixels (and not others), click on the signature when it's loaded in the input area. Alternatively, you can specify the original ink color in the options. If some pixels on the edges of the signature weren't turned black, increase the color detection threshold in the options. Additionally, instead of the black color, you can use any other color for the new signature. For example, you can create a grayscale signature if you enter "gray" as the output signature color. Png-abulous!

In this example, we convert Salvador Dali's blue signature into a black signature. As the original signature is blue, we enter the color "blue" in the options and get it back in black pixels. The background of the signature is transparent as both the input and the output are transparent. (Source: Wikipedia.)
In this example, we draw Pablo Picasso's digital signature in black-and-white tones. We determine the color of the original signature's ink by clicking on it in the input area. In addition to the green color, we convert an additional 20% of pixels of similar tones to black-and-white. As a result, we get a black signature on a white background. (Source: Wikipedia.)
In this example, we use a dark-slate-gray color as the new color instead of the default black color. We load Ernest Hemingway's signature written with a brown pen into the input and turn all the brown pixels plus 35% similar color shades around signature edges into gray color. (Source: Wikipedia.)
