1Introduction
The full-width half-width converter tool can quickly convert full-width characters (such as ＡＢＣ１２３) to half-width characters (such as ABC123), or vice versa. Full-width characters occupy two bytes, half-width occupy one, and conversion is often needed in programming and data processing. The tool provides two conversion directions: full-width to half-width and half-width to full-width, selectable via the dropdown menu. You can also choose whether to convert punctuation. The converted text retains the original format, making it easy to copy and use directly. Runs locally, safe and reliable.
