OpenCC is an open-source C++ library and toolset for high-quality, deterministic conversion between Traditional Chinese, Simplified Chinese, Japanese Shinjitai, and regional wording across Mainland China, Taiwan, and Hong Kong. It uses decoupled, extensible dictionaries with phrase-level and variant-aware rules, and ships bindings for Python and Node.js plus CLI tools.

Use cases

• convert simplified Chinese text to traditional Chinese
• convert traditional Chinese to simplified with Taiwan or Hong Kong regional wording
• handle one-to-many simplified-to-traditional character mappings correctly
• convert Chinese text offline without LLMs
• customize Chinese conversion dictionaries for a project
• convert Japanese Shinjitai kanji to Chinese variants

When to choose

• you need predictable, auditable, dictionary-based Chinese conversion rather than machine translation
• you need phrase-level and regional vocabulary conversion (e.g. 鼠标/滑鼠) across Mainland, Taiwan, and Hong Kong conventions
• you need offline, fast conversion with bindings for C++, Python, or Node.js
• you want to extend or replace conversion dictionaries with your own rules

When to avoid

• you need translation between Chinese languages such as Mandarin and Cantonese
• you need general machine translation between Chinese and other languages
• you need fuzzy or context-based translation rather than deterministic rule-based conversion
