It excels at removing accents (diacritics), transliterating non-Latin scripts (like Cyrillic or Greek) to ASCII, and standardizing text for database search indexing. Whether you are built search algorithms or cleaning up international user data, this tool ensures your text is consistent and machine-readable.

  • 2Select 'Remove Accents' to strip diacritics (e.g., 'é' -> 'e').
  • 3Select 'Transliterate' to convert non-Latin scripts to Latin characters.
  • 4The tool uses NFKD normalization and custom mapping tables.
  • 5Copy the normalized text instantly.

Frequently Asked Questions

Everything you need to know about using this tool effectively and securely.

Q.Does this translate languages?

No, this is a transliteration and normalization tool. It changes the *script* or *characters* to a standard form, but it does not translate the *meaning* (e.g., it won't change 'Gato' to 'Cat').
