Does this tool send my text to a server?

No. All processing happens entirely in your browser using the JavaScript String.prototype.normalize() API. Your text never leaves your device.

Which characters are affected?

Any character that can be decomposed via Unicode NFD normalization followed by removal of combining diacritical marks (U+0300–U+036F). This covers most Latin-script accents: acute, grave, circumflex, umlaut, tilde, cedilla, macron, and more.

Will letters like "ß" or "æ" be converted?

Ligatures and characters without a base+diacritic decomposition (like ß or æ) are left unchanged, since they are not diacritically modified base letters.

Can I use this for generating URL slugs?

Yes. After stripping accents, additionally replace spaces with hyphens and remove any remaining non-ASCII characters to produce a valid ASCII slug.

Summary

Paste text with accented characters and instantly get a clean version with all diacritics stripped.

How it works

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
