This tool makes specific areas of the given stamp or seal transparent. It can remove the background and refine the edge transparency of a stamp so that it looks as if it was printed on your documents with a real rubber stamp. Typically, stamps have a white background or another shade of the paper used in the document. To remove the shade used in your stamp, click on it in the input window or select the color in the options using a color code or color picker palette. You can also adjust the sensitivity percentage of color removal by controlling how many similar shades will be included in the removal process. Setting it to 0% removes only one exact color, while 10-20% removes multiple related shades. You can improve the stamp's edges by making the pixels on the edges slightly transparent. To do this, specify the smoothing radius in the options, such as 1, 2, or 3 pixels. If the stamp itself contains white areas, and you only want to remove the white background surrounding the stamp, activate the "Match Pixels Outside" option. This will only edit the areas outside the stamp, between its outer border and the edges of the image. To ensure that transparency is applied to all right areas, enable the "Show Transparent Area" option, which displays transparent areas in black color and the rest in white color. Png-abulous!

In this example, we use our tool to remove the solid white background from a PNG stamp labeled "Top Secret". With the background removed, the stamp turns into a digital PNG stamp that can be used in various projects and documents as it's see-through. To do it, we set the "Transparency Color" option to "white" and the "Transparent Color Similarity Percentage" to "60%" to ensure that all similar white shades around the stamp are also made transparent.

In this example, we make the background around the St. Xavier High School's official seal transparent. As you can see, the white color here is used not only as the background around the seal but also inside the seal itself. To match only the white background around the seal, we enable the "Match Pixels Outside" option. Additionally, we set the color removal threshold to 30% and smooth the edges of the seal with a radius of 1 pixel. (Source: Wikipedia.)
In this example, we're working with a visa stamp from a German passport. When a traveler arrived in Munchen, this stamp was printed in her passport. Now we want to separate it from the passport's paper color. We can do it quickly by picking the passport page's color and setting the color similarity index to 22%, which matches lighter and darker passport page shades. We also make the pixels at the edges of the stamp slightly transparent to fully remove any leftover background. (Source: Wikipedia.)
