Hanko stamp maker
Make a red Japanese seal (hanko / inkan) with 1–4 characters, round or square, and download it as a transparent PNG or SVG, or stamp it straight onto a PDF.
The seal uses a Mincho font installed on your device. The SVG keeps the text as text, so it looks the same only where that font exists; the PNG and the stamped PDF are fixed images.
How it works
- Characters are set in a Mincho typeface and squeezed to fill the seal, the way carved seals are. Four-character seals read right column first.
- For PDFs, click the spot on the page where the seal goes. It is drawn with multiply blending, so the text underneath stays readable, like real ink.
- Everything is drawn in your browser; neither the seal nor the PDF is uploaded.
Questions
Is this a legally valid seal?
It is a picture of a seal, fine for internal approvals and documents where an image stamp is accepted. It is not a registered seal (実印) and not a digital signature.
The characters look wrong or show as boxes.
The seal uses a Mincho font installed on your device. Windows, macOS, iOS and Android include one; on some Linux systems install Noto Serif CJK.
