Full-width to Half-width
Features & Usage
Full-width to Half-width is a secure, real-time converter designed to translate full-width Japanese characters (Zenkaku), including Latin letters, numbers, symbols, and katakana, into compact half-width characters (Hankaku). Essential for web developers writing code, software engineers normalizing source configuration files, database administrators cleansing user tables, and financial analysts preparing zip codes or phone numbers for rigid banking forms. The algorithm automatically downsizes wide English text while neatly splitting compound full-width katakana into single half-width equivalents. Because privacy is our priority, all conversion logic executes locally in your browser. This guarantees that confidential database strings or personal contact lists remain entirely private, avoiding any server-side logs.
