Chinese Contract Seal Generator

Design a dedicated Chinese contract seal (合同专用章) — a round red seal whose bottom text marks it for contract use, so a company can authorize agreements without exposing its primary company seal.

About this seal

A contract seal is a special-purpose seal carrying the wording 合同专用章 ("dedicated contract seal"). Many Chinese companies use it instead of the main company seal for day-to-day agreements, limiting how often the primary seal is used. It keeps the round official format — company name on the top arc, a star or blank center, and an optional anti-counterfeit code.

Common uses

Signing commercial and supply contracts
Framework and purchasing agreements
Letters of intent and memoranda of understanding
Delegating contract authority to a department

How to create it

Open the template — the contract-seal layout with 合同专用章 is pre-applied.
Enter your registered company name on the top arc.
Keep or edit the 合同专用章 bottom text.
Set the diameter to the Ø40mm standard at 300 DPI.
Export a transparent PNG or SVG ready for your contract files.

Frequently asked questions

What is the difference between a company seal and a contract seal?

The company seal (公章) is the company's highest-authority seal; the contract seal (合同专用章) is a special-purpose seal used specifically for contracts, often to reduce reliance on the main seal.

Does a contract seal need an anti-counterfeit code?

It is optional. The editor lets you add a 13-digit security code along the bottom arc if your design uses one.
