What is a transparent png signature maker?

learn more about this tool
This online browser program creates transparent PNG signatures. You can easily and quickly create a digital signature (also known as an "esignature") or a branded company stamp on a transparent background. In the input field, the program accepts an opaque image of a PNG signature, any picture from your phone or camera, or a digital scan of a signature written on paper. In the options, you can specify the paper color or the background color. This color can also be changed by clicking on any new color of the signature. You can also remove slightly similar color tones by increasing the color similarity percentage. Additionally, you can make the outline of the signature smooth by setting a positive smoothing radius in the "Refine Signature Outline" option. To make sure the correct areas of the signature are transparent, you can use the "Show Opacity Mask" option. Png-abulous!

William Shakespeare's Signature
This example creates a transparent digital signature from an opaque image of William Shakespeare's signature. It automatically finds all non-transparent colors and makes them transparent. In addition to the white non-transparent tones, it also includes all grayish shades that are 40% similar to the white color. The result is a crisp black see-through signature that can be imported into any Office document. (Source: Wikipedia.)

George W. Bush's Signature
In this example, we're working with a PNG version of George W. Bush's signature written on a gray background. We click the left corner of the PNG in the preview area to select the color code of the background and delete the selected color together with 5% similar color shades. Additionally, we smooth the pixels around the edges of the signature with a radius of 1 pixel. (Source: Wikipedia.)

Thomas Edison's Signature
In this example, we remove the paper background from Thomas Edison's signature. The paper has a light blue color and we find its RGBA color code by clicking on this color in the input. As this blue color has slight light and dark variations, we also match 10% of similar tones. To make the pixels along the edge of the signature sharp, we activate the "Refine Signature Outline" option. (Source: Wikipedia.)
