Romaji Converter

Summary

Paste hiragana or katakana text and get the Hepburn romaji transliteration instantly in your browser.

How it works

1. Paste or type hiragana or katakana into the input box.
2. The tool maps each kana character to its Hepburn romaji equivalent.
3. Digraphs like きゃ (kya) and contracted sounds are handled automatically.
4. Long vowels in katakana (ー) are written with a macron or doubled vowel.
5. Non-kana characters (kanji, Latin, punctuation) pass through unchanged.
6. Click "Copy Romaji" to copy the result to your clipboard.
