Half-width to Full-width
Convert half-width letters, digits, and common punctuation to full-width. Useful when preparing Japanese copy that needs even visual spacing, or when half-width alphanumerics should match full-width layout.
How to use
- Conversion covers half-width alphanumerics and common symbols, leaving Chinese characters and kana unchanged.
- Full-width characters take more room, so check tables and buttons for text overflow after conversion.
FAQ
Is full-width suitable everywhere?
No. URLs, code, and email addresses normally need half-width characters and may stop working after conversion. Check that the target environment accepts full-width characters before publishing.
Why did some symbols stay the same?
Not every half-width symbol has a commonly used full-width counterpart, so unlisted ones remain as they are. Check the punctuation afterwards and adjust by hand to avoid mixing styles.
