This browser-based utility lets you add text to a digital stamp or seal and save the new updated stamp as a losless PNG image. It's especially useful for applying serial numbers, dates and times, personalized messages, or any other information that changes frequently on a predefined stamp design. For example, you can upload a ready-made stamp template and add any text you need, such as "APPROVED", "#12345", "2025-01-01", or even a multi-line message. To make sure the text looks neat on your stamp, you adjust the font size (character size in pixels) and line height (spacing between lines of text). You can also choose a text color that matches your stamp's design using the built-in color picker. Similarly, you can set a background color for the text area. If you want the text background to remain transparent, simply leave that field empty or enter the color name "transparent". Text can be styled using one of the built-in system fonts (like Monospace, Serif, Sans-Serif, Arial, Helvetica, Roboto, and more), or you can use a custom font. To use your own font, paste its URL into the text field and select the "Custom" font option. You can also apply bold or italic styling to the font if needed. To precisely position the text on your stamp image, use the options in the fourth column. Here you can adjust the horizontal and vertical offsets to move the text in any direction, and set the width and height to define the text area size. Alternatively, you can drag and resize the text area directly in the input editor with your mouse. Finally, use the text alignment option to position the text inside its container. You can left-align it, right-align it, or center it. If you don't yet have a stamp template and want to design one from scratch, use our Custom Stamp Maker tool. Png-abulous!

In this example, we add the serial number "0001" to a designated ID field in a digital PNG stamp template. Such stamps are often used for marking documents with serial numbers, adding tracking codes to shipping labels, or labeling registration IDs. Instead of creating a new stamp design each time, we upload an existing template with a blank space for the number and simply insert the needed number in this place. We center the number, use a bold Tahoma font at 65px, and keep the text color black to match the original stamp design.
In this example, we add an approval label to a blank seal template. The uploaded seal features an empty frame with empty space in the center, allowing us to insert any text label or message. Given the green color of the seal, which symbolizes approval, we insert the word "CONFIRMED" in the center. We match the text color to the seal's color and choose the bold "Impact" font with a size of 100 pixels. (Source: Freepik.)
In this example, we replace the existing text on a stamp. The original uploaded stamp contains the word "failed" in small, inconspicuous letters. To make the label clearer and more noticeable, we replace this text with an uppercase word "FAILED". To do it, we apply a bold style and increase the text size to 60 pixels. To make sure that the original stamp text is no longer visible, we add a white background fill to the text container. This white fill effectively covers the underlying text. Additionally, we use a unique custom font called Orbitron, which we load from a Google Fonts URL. (Source: Vecteezy.com.)
