About Seal Generator

Seal Generator is a browser-based tool for designing seals and stamps — official seals (gongzhang), hanko, dojang, and Western round company and notary stamps. You customize the text, fonts, colors, borders, center elements and effects, preview the result live, and export a transparent PNG, JPG or editable SVG.

It is built for one job done well: producing accurate, regional-correct seal artwork for samples, mockups, design and lawful personal use — instantly, in your browser.

Where generic stamp makers treat a "seal" as a red circle with text, we model the conventions that make a seal look right: GA 241 standard diameters, the golden-ratio five-point star, FangSong engraving fonts, curved main text, anti-counterfeit codes, oval invoice seals, and riding-seam (qifeng) seals.

For Japan we follow maru-in and kaku-in conventions in Mincho type; for Korea, beobin ingam and the Myeongjo style; for Taiwan and Western markets we adapt the layout and identifiers accordingly rather than forcing one region's rules onto another.

This cross-regional depth is the core of what we do.

Your seal is drawn entirely in your browser. The text you type, the seal you render, and the images you export never leave your device — nothing is uploaded to a server.

Share links contain only the parameters you choose to encode, so you stay in control of what you pass on. Payment verification and anonymous analytics are separate, clearly-disclosed services described in our Privacy Policy.

For businesses, legal teams and government users who cannot send seal content to a third party, local-only rendering is a deliberate, foundational choice — not an afterthought.

Seal Generator is intended for samples, demonstrations, internal review, visual design and lawful personal use. A generated seal image is not a verified electronic signature and is not a substitute for an authorized, legally compliant signing service.

Using the tool to forge seals, create fraudulent certificates or contracts, or produce legally binding documents without authorization is strictly prohibited. Used responsibly, the tool helps you visualize and design — not deceive.

The tool, templates and legal pages are available in English, Simplified Chinese, Traditional Chinese, Japanese and Korean, with region-appropriate templates and fonts for each market.
