JPG to PNG Signature Converter

Online PNG Maker

World's simplest online JPG signature to PNG signature converter. Just import a photo or a scan of your signature in the JPG format in the editor on the left, select the background color, and you'll instantly get a signature in the PNG format without the background on the right. Free, quick, and very powerful. Created with love by team Browserling.

᠎᠎᠎          Tool Options

Signature Background Color

make transparent.
(Or click on the signature's
background in the input area).
Remove more background pixels
by increasing the color matching
threshold (25% by default).

Refine Signature Edges

Remove the noise pixels around
the digital signature edges.
Set the radius of pixels to
remove around the edges.

Transparent Signature Preview

of the pixels that will be made
transparent.

What Is a JPG to PNG Signature Converter?

This online browser program converts a JPEG signature to a PNG signature. The key feature of a PNG signature is its transparent background. Unlike the JPEG format, which is always opaque, the PNG format supports an alpha channel, which allows pixels to have transparency. A signature with a transparent background is called a digital signature as you can use it in PDF documents, Word documents, and services that require you to upload your signature. By default, this program detects and removes the white background and related paper-gray tones. If you have a background in a different color, then just click on the background in the input screen and the program will remove exactly this color. You can also expand the number of similar pixels that will be removed via the "Color Threshold" option and smooth the pixels around the signature edges via the "Signature Edge Smoothing" option. The smoothing is controlled by the pixel radius, which can be 1px, 2px, 3px, and so on. To see a high-contrast version of your digital signature, enable the "Preview Transparent Signature" option. You can download the final PNG signature via the Save-as button that is located below the output area. Png-abulous!


JPG to PNG Signature Converter Examples

George Washington's Signature

In this example, we convert the JPG version of George Washington's signature to a PNG signature. We delete the white background by entering "white" in the color option and increase the color threshold to 35% to get rid of all JPG artifacts. (Source: Wikipedia.)

Marilyn Monroe's Signature

In this example, we create Marilyn Monroe's digital signature. We upload a JPG photo of her signature and remove the paper background from it. As the photo has very high quality, we have to match just 8% of other paper colors (such as light gray). In addition, we refine the signature edges by smoothing the pixels around them within a one-pixel radius. (Source: Wikipedia.)

Vintage Stamp

This example turns an opaque JPG stamp into a transparent PNG stamp. Even though the background of the stamp is non-uniform (it has light and dark patches of brown color), the program still successfully removes all the background pixels and leaves only the stamp pixels. (Source: Pexels.)
