Accent / Diacritic Remover

Summary

Instantly remove diacritical marks from any text. Converts accented letters like é, ü, ñ, ç, â into their plain ASCII equivalents using Unicode NFD normalization — all client-side, nothing uploaded.

How it works

1. The tool applies String.prototype.normalize("NFD") to decompose each accented character into its base letter plus a separate combining diacritic code point, then strips all combining characters in the Unicode range U+0300–U+036F using a regular expression.

Use cases

• Normalize user-submitted names or addresses for database storage.
• Prepare text for ASCII-only systems that cannot handle Unicode.
• Generate URL slugs from titles containing accented letters.
• Clean imported CSV data with mixed accent conventions.
