Tips
- Fullwidth characters are common in CJK contexts; halfwidth is standard ASCII. This tool converts letters, numbers, symbols, and spaces.
- Punctuation like commas, periods, colons, and brackets are normalized between fullwidth and halfwidth.
- If your text mixes both widths, choose the direction you need; the other characters remain unchanged.
