Half-width to Full-width
Features & Usage
Half-width to Full-width is an elegant online conversion tool built to instantaneously transform half-width alphanumeric, punctuation, and Japanese katakana characters (Hankaku) into their full-width counterparts (Zenkaku). This utility is indispensable for formatting official Japanese business documents, academic papers, and preparing text for legacy database fields or administrative web forms that strictly enforce full-width inputs. Its kana conversion engine ensures that compound half-width characters, including those with voiced and semi-voiced marks (such as ｶﾞ or ﾊﾟ), are accurately merged into single cohesive full-width symbols. The entire process runs strictly inside your local web browser, meaning your private drafts or proprietary files never touch our servers. Use this tool to easily normalize database exports and polish layout aesthetics.
