Why is Traditional to Simplified conversion described as lossy?

Several distinct Traditional characters were merged into a single Simplified character. For example 麵 (noodles) and 麪 both map to 面, which also already means face. Going from Traditional to Simplified therefore discards a distinction, and the reverse direction cannot always recover the original.

Is this a word-level or character-level conversion?

It is a character-by-character substitution using an OpenCC-derived reverse table. It does not rewrite regional vocabulary, so a Taiwan term may convert character-for-character rather than to the mainland equivalent word. Review specialised vocabulary afterwards for natural mainland phrasing.

Why are some characters left unchanged?

The two scripts share most characters, so only the characters that differ are substituted. Punctuation, digits and Latin text always pass through untouched, and the tool reports how many characters were actually changed.

Does my text stay private?

Yes. The reverse mapping table is embedded in the page and all conversion runs locally in your browser. No text is sent to a server, so the tool works offline once loaded and is safe for confidential documents.

Will the output always be correct mainland Chinese?

The character forms will be Simplified, but because conversion is character-level it may keep Taiwan-style word choices. For polished mainland text, proofread for vocabulary such as 軟體 to 软件 (software) after converting the script.

The Traditional to Simplified Chinese Converter rewrites Traditional text — as used in Taiwan, Hong Kong and Macau — into the Simplified characters standard in mainland China. Paste a passage and each differing character switches to its Simplified form while shared characters stay put, making it handy for localisation, study, subtitles and cross-strait communication.

How it works

The tool carries an embedded Traditional-to-Simplified table derived from the open-source OpenCC project. It scans your text one character at a time: characters present in the reverse table are replaced with their Simplified equivalent, and everything else is left intact. Since most characters are common to both scripts, only the few hundred that truly differ are changed, and a counter shows how many substitutions were made.

Notes and limitations

Traditional-to-Simplified conversion is inherently lossy in places because Simplified Chinese merged several originally distinct Traditional characters into one. For instance both 麵 (noodles) and the surname-era variant collapse onto 面, which also means face. When more than one Traditional character maps to the same Simplified one, this converter uses the most common mapping. The conversion is also character-level, so it does not automatically swap regional vocabulary — a Taiwan term like 軟體 becomes 軟体-style characters rather than the mainland word 软件. Proofread specialised vocabulary for natural mainland phrasing after converting. All processing happens locally in your browser, so nothing is uploaded and the tool works offline once loaded.
