About Simplified ↔ Traditional Chinese
Mainland China and Singapore write Chinese with simplified characters, while Taiwan, Hong Kong and Macau keep the traditional forms. The words are largely the same, but a text written for one audience looks foreign to the other, so subtitles, product pages, letters and school material often need both versions.
Converting is not a one-to-one swap. Several traditional characters were merged into one simplified character, so the converter has to read the word around it: 干 is 乾 in 干净 (clean), 幹 in 干部 (cadre) and stays 干 in 干涉; 发 is 髮 in 头发 (hair) and 發 in 发展 (development). This tool uses OpenCC, the open-source converter whose dictionaries of characters and phrases resolve these cases.
Traditional Chinese is not uniform either. Taiwan writes 裡 and 著 where Hong Kong writes 裏 and 着, and Hong Kong prefers 台灣 to 臺灣. Pick Taiwan, Hong Kong or the standard OpenCC forms for the output. With Taiwan vocabulary on, words that differ between the mainland and Taiwan are swapped too: 软件 becomes 軟體, 信息 becomes 資訊, 打印机 becomes 印表機 and 出租车 becomes 計程車, and the reverse direction turns them back.
Word documents keep their formatting while their text is converted, and subtitle and plain-text files work as well.
The dictionaries download once, the first time you convert (about 450 KB for simplified to traditional, 50 KB for the reverse), and then work offline. Rare names and new slang can still come out with the wrong variant, so proofread anything that will be published.
