When to use them

Title case: mind the conventions

English title case capitalises most words in a title, but style guides differ: many keep short articles, conjunctions and prepositions ("a", "and", "of") in lower case unless they come first. The tool capitalises every word, so check those small words afterwards if you follow such a guide. Many other languages, including French and Spanish, capitalise only the first word and proper nouns; for them, sentence case is usually the right choice.

Capitals and readability

A long text in capitals is slower to read: you lose the word shapes that help recognise them. Online, it also comes across as shouting. Keep capitals for short headings, acronyms and warnings.

Privacy

The transformation happens entirely in your browser; the text is neither sent nor stored.

Frequently asked questions

Is the text sent anywhere?

No, the transformation happens entirely in your browser.

Are accents preserved?

Yes. Accented letters are converted correctly in both directions, for example "é" to "É".

Does sentence case handle proper nouns?

No: it capitalises the start of each sentence and lowers everything else. Read through afterwards to restore capitals on proper nouns.

Can I undo a transformation?

Use your device's Undo shortcut (Ctrl+Z or Cmd+Z) in the text field, or paste your original text again.
