This tool adds a background to transparent digital stamps and seals. Electronic stamps often have a transparent background and use the PNG file format, making them easy to overlay on documents and images. However, in some situations, adding a background and converting them to non-transparent format is necessary. For example, when uploading a stamp to a website that doesn't support PNG transparency, you can add a white background and make it opaque without transparent pixels. Or, when printing documents, the stamp may blend into the paper, so a solid background ensures that the stamp is highly visible. Or, when copying a stamp to clipboard, the transparency may get replaced with black color. A background can also improve contrast, making the stamp more stand out on any document or website. Additionally, some programs do not support transparency at all, which can cause unexpected visual artifacts. This tool provides a simple way to add a background with just one option where you can enter the background color. You can specify the background color in several ways: by color name (e.g., "white" or "gray"), by hex code (e.g., "#F0FFFF" for azure), by RGB code (e.g., "rgb(255, 250, 240)" for floral white), or by RGBA code if you want a semi-transparent background (e.g., "rgba(255, 255, 0, 0.5)" for 50% translucent yellow). Additionally, you can simply select a color via the built-in color picker. If you need to remove the background from a stamp instead, you can use the Remove Stamp Background tool. Png-abulous!

In this example, we add a white background to the "ACCEPTED" stamp. This type of stamp is commonly used on invoices and approval forms to indicate that a request or transaction has been officially accepted. Adding a white background ensures that the stamp remains clearly visible regardless of the color or pattern of the underlying document. (Source: Vecteezy.com.)
In this example, we fill the background of an antique Fulton County Superior County seal with the parchment color. As this seal is very old and contains many intricate details, the parchment color is the right one for its background. A filled background preserves the clarity of the seal's complex design and also gives it an old look. (Source: Wikipedia.)
In this example, we convert a transparent "Coming Soon" stamp into a semi-transparent one by making by adding a lavander-colored background with 30% transparency. Coming soon stamps are often used in ads to promote upcoming events, so maintaining its eye-catching design is important. The 30% see-through lavender background complements the stamp's color scheme and helps it remains visible on any printed material. (Source: Freepik.)
