The full-width/half-width converter switches freely between full-width and half-width characters: a full-width character occupies two standard character positions while a half-width character occupies one, showing the difference between them.
1, a full-width character takes 2 bytes, a half-width character 1 byte
2, Full-width means letters, digits and so on take up the same width as Chinese characters; half-width means ASCII-style characters
3, Letters, digits and characters typed when no Chinese input method is active are all half-width
This tool belongs to the “Text processing” category.
Your input is processed locally in the browser whenever possible. We do not store it.
Chinese is counted per character; English is reported both per character and per whitespace-separated word.
Bounded by the browser and the request size. Tens of thousands of characters are routine; split a whole book into chunks.
Many characters map one-to-many and need context. The tool uses common mappings — proof-read proper nouns.
