Make a Japanese square company seal (kakuin, also called shaban) from a company name and download it as a transparent PNG. Enter a company or shop name (such as a corporate name or trade name) and the characters are laid out on a square seal face instantly, with a live preview. Choose the typeface (serif/Mincho or sans/Gothic), color (vermilion, red, maroon or black), size (21–30 mm square), whether to show the square frame, and the output resolution (DPI) — these style choices are remembered next time, while the company name is never stored. Pick a vertical layout (the traditional square seal) or horizontal, and the characters are arranged into rows and columns automatically by length. The output is a transparent PNG, so you can drop it directly onto an invoice, quotation or delivery note you built in Excel, or onto a Word document or PDF — no scanning a physical stamp, no fiddling with shapes in a spreadsheet. The company name and the generated image are never uploaded or stored (only the style options are kept in your browser). Everything runs locally. Note that this creates the look of a seal image only; it does not register a seal or confer any legal validity.
