Why Remove Accents and Diacritics from Text?
Diacritical marks (accents like é, ñ, ü, ç, à) are essential for proper pronunciation in many languages, but they create compatibility issues in ASCII-only systems, URLs, email addresses, database keys, and search optimization. This free online diacritics remover instantly converts accented characters to their plain ASCII equivalents, making text compatible with older software, web systems, and international platforms that require English-only characters.
Whether you're creating URL-friendly slugs, preparing data for legacy databases, optimizing content for SEO, or ensuring compatibility with email systems, removing diacritics is essential. This tool works with all languages including French, Spanish, Portuguese, German, Italian, Polish, Czech, Vietnamese, and more—handling every Unicode combining diacritical mark defined in the specification.
Common Use Cases for Removing Accents
🔗URL Slugs & Web Development
Create clean, SEO-friendly URLs by removing accents from page titles, product names, and blog post slugs. URLs like "café-parisien" become "cafe-parisien" for better compatibility and SEO performance. Essential for international e-commerce sites, multilingual blogs, and content management systems. Combine with our Slugify tool for complete URL generation.
📧Email Addresses & Usernames
Many email systems and authentication platforms don't support accented characters in email addresses or usernames. Convert names like "José García" to "Jose Garcia" for account creation. Critical for user registration systems, CRM imports, and international customer databases where ASCII-only characters are required.
🔍SEO & Search Optimization
Improve search engine compatibility by normalizing accented keywords to plain ASCII. Search engines sometimes treat "café" and "cafe" as different terms—removing accents ensures your content ranks for both variations. Perfect for meta tags, alt text, and file names. Use Text Statistics to analyze keyword density after conversion.
💾Database Keys & Programming
Legacy databases, programming variables, and API endpoints often require ASCII-only characters. Convert accented names to plain text for database column names, JSON keys, function names, and file paths. Essential for internationalization (i18n) projects and cross-platform data exchange. Pair with Case Converter for camelCase or snake_case formatting.
How Diacritics Removal Works
This tool uses Unicode Normalization Form D (NFD) to decompose characters into their base letters and separate combining diacritical marks. For example, "é" (U+00E9) is decomposed into "e" (base letter) + "´" (combining acute accent, U+0301). The tool then removes all combining marks in the Unicode range U+0300 to U+036F, leaving only the base ASCII characters.
This method handles hundreds of accented characters including: à è ì ò ù (grave accents), á é í ó ú (acute accents), â ê î ô û (circumflex), ä ë ï ö ü (umlaut/diaeresis), ã õ ñ (tilde), ç (cedilla), ą ę (ogonek), ć ń ś ź (acute accent on consonants), and many more from European, Vietnamese, and other languages.
All processing happens locally in your browser with a 300ms debounce for optimal performance. Your text never leaves your device, ensuring complete privacy. After removing diacritics, consider using Remove Emojis or Trim Lines for additional text cleanup.

- •Database preparation: Combine with Remove Emojis and CSV Safe for complete data sanitization before database imports.
- •Batch processing: Process entire documents, contact lists, or product catalogs at once—the tool handles large text volumes efficiently with real-time preview.
- •Special characters: This tool specifically targets diacritical marks. For other character removal needs, use Find & Replace or Remove Commas.
