What does converting katakana to hiragana mean?

It replaces full-width katakana characters (like カタカナ) with their matching full-width hiragana (かたかな). Katakana and hiragana map cleanly onto each other in Unicode, so each character is converted to its hiragana counterpart exactly as it appears.

What happens to the long vowel mark ー?

The long vowel mark ー (U+30FC) is shared by both katakana and hiragana, so it is left unchanged. For example, コーヒー becomes こーひー.

Can it convert half-width katakana?

This tool converts full-width katakana (ア–ヶ) to hiragana. Half-width katakana (ｱ–ﾝ) is left as-is. If you have half-width kana, convert it to full-width katakana first with a full-width / half-width converter, then use this tool.
