Conversion changes writing systems. Translation changes language.
If a sentence is 我学习中文, a Traditional conversion can produce 我學習中文. An English translation would be "I study Chinese." Those are different products. ChineseDocConverter does the first job. It will not write the English sentence, and it will not write a Japanese or Korean sentence either.
People mix the two words because both start from a Chinese file, and because marketing pages sometimes say "translate to Traditional Chinese." In publishing, that phrase usually means: change the characters, maybe adjust a few regional words, and leave the meaning in Chinese. It does not mean hire a literary translator.
The same meaning, a different standard
Simplified and Traditional Chinese are two ways of writing Chinese, explained in Simplified vs Traditional Chinese. A converter's job is to move a text from one published standard to another so that a school, a government office or a phone can display the expected shapes.
The meaning of the sentence is supposed to stay put. 学习 and 學習 are the same word. 国 and 國 are the same word. The converter is closer to changing American color to British colour than it is to turning an English paragraph into French.
Even that analogy is slightly too kind. English spelling reform did not merge meet and meat into one spelling that later has to be split again. Chinese simplification did merge some characters. When a converter has to un-merge them, it is still doing character work, not translation, but it can pick the wrong character. That error looks like a wrong word. It is still not an English translation error.
Why the mix-up happens
Software stores Chinese as Unicode code points. Users see "Chinese" in a language menu. Product managers then ask for a "Chinese translation." Sometimes they need Simplified strings for mainland China. Sometimes they need Traditional strings for Taiwan. Sometimes they need an actual English UI.
Those are three requests:
- Keep Chinese, change the character standard. Use a converter.
- Keep Chinese, change regional wording. Use a converter with phrase tables, then a local editor.
- Change the language. Use a translator.
If you only needed (1) and you hired a full translation team, you spent money on meaning that was already finished. If you needed (3) and you ran OpenCC, you still have a Chinese page.
Search engines and app stores add to the confusion. A listing may ask for "Chinese (Simplified)" and "Chinese (Traditional)" as if they were languages. For catalog purposes they behave like locales. For the writer, they are still Chinese.
What a converter will not do
- It will not turn Chinese into English, Japanese, Korean, Vietnamese or any other language.
- It will not localize jokes, metaphors, legal disclaimers or marketing slogans.
- It will not decide whether a Mainland brand name should be rewritten for Taiwan advertising law or taste.
- It will not decide whether 后 should become 後 ("after") or stay 后 in a name without dictionary context.
- It will not add Pinyin. Pronunciation spelling is a different tool: the Pinyin converter.
- It will not fix a file whose characters are already destroyed by the wrong encoding.
Phrase-aware OpenCC types can swap some regional nouns. That is still a word-list operation. It is closer to a glossary than to a translator who asks what the reader fears, laughs at, or must sign.
When you need a translator instead
Hire a translator when the reader does not read Chinese, or when the Chinese must be rewritten for a new market even if the characters stay in the same family.
Examples:
- A contract that must be enforceable in English.
- A novel whose jokes depend on mainland internet slang.
- A Hong Kong Cantonese column that you want as Taiwan Mandarin prose, not merely Taiwan glyphs.
- A medical consent form that has to match local legal wording, not a character-for-character map.
In those jobs, running a converter first can still help the translator if they prefer to work from the target character set. It does not replace them.
A practical test
Take one sentence from your file and ask: "If every character were already in the target standard, would a native reader in that city accept the wording?"
- If the answer is yes, you needed conversion.
- If the answer is no, because the jokes, titles or legal terms are wrong for that city, you needed editing or translation on top of conversion.
- If the reader cannot read Chinese at all, you needed translation from the start.
Use the text converter when the language is already Chinese and only the character set should change. Use the document converter when that Chinese lives inside Word, Excel, PowerPoint or PDF.
Frequently asked questions
My client asked me to "translate this into Traditional Chinese." What should I do? Ask whether they want Taiwan or Hong Kong characters, and whether the wording can stay as written. Then convert and proofread. If they wanted English, that request was misnamed.
Can machine translation replace OpenCC? Machine translation may emit Traditional characters, but it is allowed to change meaning. A converter is supposed to preserve meaning. Do not use a translator when you only needed glyphs.
Does adding Pinyin count as translation? No. Pinyin is a pronunciation aid. The language remains Chinese.
If phrase tables change words, isn't that translation? It is glossary substitution. Translation includes meaning, tone, audience and legal effect. A phrase table does not carry those responsibilities.
