Create professional company stamps online — no design skills required. Choose between round stamps (common for official seals in China and East Asia) or square stamps (common for contract-specific seals). Customize the text, color, and style.

The stamp is exported as a transparent PNG file, which you can directly use as a signature image in any PDF signing tool, Word document, or image editor.
