This tool removes extra borders and padding around rubber stamps and seals. It also works with digital stamps in PNG format. When a stamp is scanned from a printed paper document, empty or unwanted space can appear around it, creating an uneven frame around it and making it harder to use digitally. The empty or unwanted space also increases the size of the PNG stamp. To make your stamp compact and neat, you can trim the border around it. Simply set the removal offsets for each side in the tool options: left-offset, right-offset, top-offset, and bottom-offset. The part of the stamp that remains after cropping is visually displayed in the input editor, where you can further adjust and fine-tune it via the interactive resizers. By default the tool works with square and rectangular stamps but if your stamp has a circular or oval shape, you can select the border removal mode that works along any circular path. Additionally, if you don't achieve perfect border removal on the first try, you can activate the function for a second pass. This option loads the output stamp as the input stamp when you press the repeat removal button and you can give it another go. Png-abulous!

In this example, we use our tool to clean up a digital stamp labeled "ACCESS DENIED". When it was exported from a graphic editor, the stamp ended up with excessive padding at the top and bottom and a lot of transparent vertical space. To eliminate these unnecessary artifacts from the file, we activate the vertical border removal mode and set the dimensions for the space to be removed above it to 208 pixels and space to be removed below it to 148 pixels.

In this example, we isolate the Bangkok, Thailand postal service seal from a scanned sheet of seals. To remove the unwanted parts of other seals and get a clean, usable Bangkok seal, we remove the borders on the left (242 pixels), right (218 pixels), top (189 pixels), and bottom (293 pixels). We use the rectangular cropping shape for this operation, which works great for the seal we're working with. (Source: Freepik.)
In this example, we refine a photo of a vintage Los Angeles stamp from 1958 by removing its outer background color. Since the stamp has an oval shape, we use the circular removal widget and carefully place it over the green contour of the stamp. After adjusting the widget boundaries to 94 pixels from the left, 132 pixels from the right, 136 pixels from the top, and 140 pixels from the bottom, we get a digital version of the oval stamp without the extra space around it.
