How does it remove the accents?

It uses Unicode NFD normalization to split each letter from its combining accent mark, then removes the marks, leaving the base letter.

Why do some letters stay unchanged?

Letters such as ł, ø and ß have no decomposed accent in Unicode, so they are left as-is rather than incorrectly mapped.

What is Unicode NFD normalization?

NFD (Normalization Form Decomposition) splits a precomposed accented character like é into its base letter e plus a separate combining accent mark. Once decomposed, the standalone marks can be removed, leaving the base letter.

Does it change the meaning of words?

It can. In many languages accents change meaning or pronunciation, so the stripped text is best used for slugs, identifiers, and matching — not as a correct spelling. Use it where ASCII compatibility matters more than orthography.

Does it handle uppercase and special letters?

Uppercase accented letters (À, É, Ñ) are stripped the same way to A, E, N. Letters with no decomposed form, such as ł, ø, and ß, are left unchanged so they are not mapped incorrectly.

Can I use this for creating URL slugs?

Yes. Removing diacritics is a common first step in slug generation, turning "Crème Brûlée" into "Creme Brulee" before lowercasing and replacing spaces with hyphens.

Q: Is my text private?

Yes. All processing happens in your browser and nothing is transmitted to any server.

Convert accented characters to their plain base letters — café → cafe, naïve → naive, résumé → resume. It is handy for URL slugs, file names, search keys, usernames, and any system that only accepts plain ASCII.

How it works

The tool applies Unicode NFD normalization to your text. NFD decomposes each precomposed accented character into its base letter followed by one or more separate “combining” diacritical marks — so é becomes e + ´. The tool then removes every combining mark (the Unicode range U+0300–U+036F), leaving just the base letters. Characters that have no decomposed form in Unicode, such as ł, ø, and ß, are left as-is rather than guessed at, so nothing is mapped incorrectly. Everything runs locally in your browser.
