Japanese Width Converter

About This Tool

Japanese text uses two character width formats: full-width (Zenkaku 全角) and half-width (Hankaku 半角). Many Japanese government forms, banking applications, and business documents strictly require one format or the other. This tool helps you instantly convert between these formats.

Examples

Common Use Cases

• Government forms requiring names in full-width katakana
• Banking forms requiring phone numbers in half-width
• Converting legacy data between different text encoding formats
• Standardizing text input for Japanese database systems
