By default, the program assumes that the original signature is black. Once you paste a PNG signature into the input field, the program will change its color to the new one. If your signature is still opaque, you can make it transparent with our Transparent PNG Signature Maker tool.

The digital signature image file usually has a PNG format as it has a transparent background color, which makes it easy to use to sign electronic documents. Similarly, you can do the reverse operation and turn a colorful signature into a black-and-white signature. For example, if you have a black-and-white signature, you can turn it blue (as if it was drawn with a blue pen), red, green, or any other color. This browser-based utility recolors a digital signature.
