This tool removes decorative borders surrounding stamps and seals. Many rubber and digital stamps have ornamental edges, such as double-line borders, wavy and spiky patterns, or dotted frames, which may not always be desirable. Borders can make a stamp look cluttered and oversized, while decorative elements and patterns can make it look informal, making it unsuitable for official documents. With this tool, you can precisely trim borders and other surrounding elements from the stamp, leaving only the core part of the stamp. To perform the trimming, adjust the border settings for each side of the stamp (left, right, top, and bottom). You can do it by specifying the number of pixels to remove in the options. You can also manually refine the crop area in the input preview by dragging the edges of the trimming area with your mouse. The tool supports the removal of borders from square, rectangular, circular, and oval stamps. For circular and oval stamps, a special mode allows you to remove the border along a curved path. If any part of the border remains after the first trim, you can use the repeated cleanup function. This feature loads the result of the first removal as the new input stamp, allowing you to make additional adjustments. Png-abulous!

In this example, we delete one of the borders surrounding a stamp labeled "LIMITED". Since the stamp has a rectangular shape, we enable the rectangular border removal mode and set the cropping area in the input editor by dragging it over the stamp. We carefully position the cutting line precisely between the two borders, which removes the thicker outer border, leaving the thinner inner border. (Source: Vecteezy.com.)
In this example, we remove the wavy border around a circular "ISO 9001" quality certification stamp in PNG format. To do it, we select the circle stamp shape in the options, measure the distance (in pixels) from the outer edge of the stamp to the inner part of the wavy border (which turns out to be 50 pixels), and cut off the wavy border. This operation produces the final stamp with a single continuous border as its outline. (Source: Freepik.)
In this example, we remove a curved text message that goes around a circular Christmas seal with a snowflake decoration. The text acts as an outer border as it fully encloses the seal, and to remove it, we trim 100 pixels from each side of the PNG using the circular trim mode. As a result, we get a simplified winter-themed seal without the outer text border. (Source: Freepik.)
