IconVault's Trad/Simp Converter switches text between Simplified Chinese and Traditional Chinese in one click using a built-in common-character table. Paste a paragraph, pick the direction, and get the converted result with a copy button. It is free and runs fully in your browser, so nothing you paste ever leaves your device.

The converter covers frequent simplified/traditional character pairs such as 爱/愛, 国/國 and 学/學, which handles everyday text like product copy, subtitles and emails. Rare or variant characters that are not in the table pass through unchanged, so always proofread names and specialized terms before publishing. There is no sign-up and no server round trip.
