  • Locale-sensitive rules are not applied — the browser default Unicode mapping is used.

Frequently Asked Questions

Why lowercase everything?

For consistent slugs, file names, CSS classes, tags and data normalization where casing must not vary.

Are numbers and symbols affected?

No — only letters change; digits, punctuation and whitespace pass through as-is.

Is my text stored?

Never. Conversion is a local string operation performed in your browser.
