Hanko / Japanese seal generator — name to 朱印-style PNG
Type a name (1–4 Japanese characters) and generate a 朱印 (Japanese name-seal) style PNG with Canvas. Choose a round / square / oval shape, a font (mincho / gothic / round-gothic), and a color (vermilion / black / navy). Transparent PNG works as a placeholder signature for e-documents, a casual avatar, or a heading flourish. Four-character names use the traditional 田 layout (top-right → top-left → bottom-right → bottom-left). Note: this is a decorative image — it does not replace a real hanko for legal contracts. Everything is rendered in your browser.
How to use
Type a name in 1–4 Japanese characters (kanji / hiragana / katakana), pick a shape (round / square / oval), a font (mincho / gothic / round-gothic), and a color. The preview updates live; the output is a transparent PNG. Use it as a placeholder signature in e-documents, a casual avatar, a heading flourish on internal docs, or a hand-made 落款 (artist seal) graphic. 1 char goes in the center, 2 chars stack vertically, 3 chars stack as 3 rows, and 4 chars use the traditional 田 layout (top-right → top-left → bottom-right → bottom-left).
FAQ
- Can it replace a real hanko (Japanese registered seal)?
- No. This is a decorative image only — it has no legal force for registered seals (実印), banking seals (銀行印), or contract seals (契約印). E-signing services (CloudSign, etc.) rely on identity verification, not the seal image, so the picture is purely visual.
- What if I enter more than 4 characters?
- Only the first 4 are used (matching traditional seal conventions). For a full name, use just the surname or trim to 4 characters like 『surname + given-initial』.
- Can I pick a color other than vermilion?
- Presets cover vermilion, black, navy, and gold; the color picker accepts any HEX. Ink-black is good for documents; navy or gold suits a corporate logo feel.
- Can I get the calligraphic 篆書 (tensho) look of a real seal?
- Not from this tool — it uses standard web fonts. For an authentic tensho-style stamp, a paid stamp-maker service is the way.
- How do I get a higher-resolution image?
- The size slider goes 200–600 px. For Retina or print, pick 400 px or higher. Don't upscale the PNG after the fact — re-render at the size you need.
