This tool enhances the appearance and clarity of digital stamps and seals in PNG format. It allows you to convert faded, pixelated, or uneven stamps into sharp, clean, and uniform ones. The tool works only with digital stamps on a transparent background. If your stamp has a solid background color or parchment-like background texture, you can remove it using our Transparent Stamp Maker tool. Once your stamp is transparent, simply import it into this tool and adjust the settings below the import area to fine-tune and improve its design. If your stamp has inconsistent or faded colors, you can apply the "Uniform Stamp Color" setting. This setting replaces the original stamp's colors with a single, high-contrast shade. It's especially useful for scanned rubber stamps, where ink may have faded or spread unevenly across the design. You can select the new color using the built-in color palette or by entering a color's name or code. Digital stamps also often require thickness adjustments for better readability. The "Stamp Thickness" group of options allows you to increase the thickness of the stamp's borders, curves, and lines. Here you can specify the new stamp thickness in pixels to add extra definition to the design. Additionally, you can choose to expand only the outer borders of the stamp, keeping the internal details like loops in letters and decorative patterns intact inside the stamp. Low-resolution photos or scans of stamps may have faint, semi-transparent pixels along the edges or within the design, which can make them look messy. The "Delete Faint Pixels" option helps clean up all these unwanted semi-transparent areas. You can adjust the cleanup threshold by setting an alpha value between 0 and 255. All pixels with an alpha value equal to or lower than the specified threshold will be removed. Finally, to eliminate rough or pixelated edges, you can use the "Smooth Stamp Edges" options. It softens the edges of your stamp by making pixels within a specified radius semi-transparent, creating a smoother, more polished appearance. For example, setting a radius of 1 or 2 pixels can significantly improve the look of jagged edges. Additionally, a stamp with smooth edges will look great on any background as the edges will blend with the background's color. Png-abulous!

In this example, a store owner contacted us to recreate a high-quality stamp from an old, worn-out stamp he found on an old product label. He wanted to use this updated stamp for printing on his merchandise packaging. The original stamp looked faded, low-contrast, pixelated, and hard to read. To fix it up, we first applied the "Set Uniform Stamp Color" option and selected the vibrant color "rgb(229, 63, 90)" to give the stamp a consistent high-contrast shade. Then, we enabled the "Increase Stamp's Thickness" option and set the extra width to 1 pixel, making the stamp's edges more visible and sharper. As a result, we got a crisp high-quality stamp that can be used for printing. (Source: Freepik.)
In this example, we're restoring a rare scanned imprint of a historical seal from 1853 for a museum. The original seal has uneven colors and is barely visible, making it hard to appreciate its design. To enhance it, we first convert all pixels in the seal to a solid black color. This color conversion standardizes the seal's design and makes it look more consistent. Then, we also activate the semi-transparent pixel cleanup option, which removes all faint pixels around the edges, giving the seal a crisp, sharp appearance. (Source: Wikipedia.)
In this example, we improve the photo studio's official stamp that's printed on business cards by adding back its color and increasing the line thickness for better visibility. We set the stamp's color to a dark navy blue and add 4 extra pixels to all stamp's lines to make it stand out more clearly. We enable the option to match only outer pixels to prevent the color from filling in the small gaps inside the letters. Additionally, we refine the edges of the stamp with a radius of 1 pixel so that it can also be used digitally. (Source: Freepik.)
