This tool allows you to create a custom digital number stamp in PNG format. A digital number stamp (also known as a numbering stamp, numeric stamp, or serial stamp) is a PNG image that looks like a real stamp and includes digits, numbers, codes, and other numerical data. Most common uses of this stamp are creating sequential serial numbers, service codes, and invoice identifiers. It may also sometimes include additional letters and special characters. The tool offers flexible customization settings for both the appearance and content of the number stamp. You can start by selecting the desired shape of your number stamp. You can choose from classic stamp forms like "Plain Circle", "Plain Oval", or "Plain Rectangle", or go for stylized forms such as "Rectangle with Ticket-shape Corners" or "Circle with Parallel Lines". To create a stamp without a visible border, you can select the "Plain Number" option. Each stamp design requires the main stamp number and, optionally, an auxiliary stamp number. Both principal and auxiliary numbers may include letters and special characters. For example, the main number of an invoice stamp may contain the letters "INV", the current year, and the sequential number of the invoice, separated by dashes, and may look like "INV-2025-0074". The auxiliary line for this stamp may say "Invoice #". If you don't enter any numbers and only leave letters, then you'll get a plain text stamp. For example, you may write "Two thousand twenty-five" to create a stamp that spells out the current year. You can set the size of the main number in the options and the program will determine the size of the auxiliary number automatically. You can separately choose the font and its style (regular, bold, italic, bold and italic together) for both the main and auxiliary labels. To do this, select a font from the provided list of fonts or activate the "Custom Font URL" mode and upload your own font by providing a URL. You can set the dimensions of your numeric stamp in pixels by using the "Stamp Width" and "Stamp Height" options. Note that for circular and oval shapes, the height is automatically calculated based on the width. You can also add padding around the stamp to avoid the imprint of the stamp being at the very edges of the stamp design, which may lead to printing defects. You can control the border thickness and shape, which can be made wavy, spiked, or decorated with star patterns, and its thickness can be set in pixels. You can also add a auxiliary border to the stamp and specify its thickness in pixels. To make the stamp more visually interesting and attractive, you can add auxiliary elements such as stars and lines. If you want a more pronounced design, you can enable the background fill option, which will paint all empty areas in the stamp in a solid color and will make the number and the auxiliary elements transparent. Each element of the stamp – the border, text, auxiliary elements (stars and lines), and background – can have its own color. You can also reduce the overall opacity to create a watermark stamp. It will be semi-transparent so if it's printed on a document, it will not hide the contents. For a worn or vintage stamp appearance, you can lower the ink density option. At 100%, the ink is solid but at lower values you'll get missing ink spots. Additionally, you can adjust the rotation of the stamp so that it is always applied to electronic documents at a specific angle. Png-abulous!

In this example, we design a simple stamp with a serial number, commonly used for tracking products, marking sequential documents, and counting inventory. It has a circular shape with an inner banner in the middle, showing the first number "0001". It also includes an auxiliary imprint below it, with a text label "SERIAL NO.". The outer edge has a thck, spiky border that's 30 pixels wide, and there's a smaller auxiliary inner border that's 10 pixels wide. The whole stamp is painted in dark blue color, the number and text uses bold Verdana font, and the ink density is set to "65%".
This example generates a seal made to label physical or digital documents with a unique archive code. This type of numbering helps efficiently organize and locate files within storage systems. The seal's design has a solid, filled rectangle shape with a wavy border and a bold label that says "ARCHIVED". The seal is green in color, slightly turned to the left (by 8 degrees), and has a subtle 10% transparency (opacity is set to 90%).
In this example, we create a stamp used for numbering pages in an old book. The stamp has a historic style with Roman numerals, a borderless layout, and short decorative corner marks made of stars. The primary imprint "PAGE I OF C" shows the page number, where the Roman letter "I" stands for page 1 and "C" stands for page 100. We load a custom font called "Prata" and generate 100 such stamps in total to individually number each page in the book.
